| 2 | Radio stars observed in the LAMOST spectral survey显示文摘Radio stars have attracted astronomers' attention for several decades. To better understand the physics behind stellar radio emissions, it is important to study their optical behaviors. The LAMOST survey provides a large database for researching stellar spectroscopic properties of radio stars. In this work, we concentrate on their spectroscopic properties and infer physical properties from their spectra,such as stellar activity and variability. We mined big data from the LAMOST spectral survey Data Release 2(DR2), published on 2016 June 30, by cross-matching them with radio stars from FIRST and other surveys. We obtained 783 good stellar spectra with high signal to noise ratio for 659 stars. The criteria for selection were positional coincidence within 1.5′′and LAMOST objects classified as stars.We calculated the equivalent widths(EWs) of the Ca II H&K, Hδ, Hγ, Hβ, Hα and Ca II IRT lines by integrating the line profiles. Using the EWs of the Hα line, we detected 147 active stellar spectra of 89 objects having emissions above the Hα continuum. There were also 36 objects with repeated spectra,28 of which showed chromospheric activity variability. Furthermore, we found 14 radio stars emitting noticeably in the Ca II IRT lines. The low value of the EW8542/EW8498 ratio for these 14 radio stars possibly alludes to chromospheric plage regions. | Li-Yun Zhang Qiang Yue Hong-Peng Lu Xian-Ming L.Han Yong Zhang Jian-Rong Shi Yue-Fei Wang Yong-Hui Hou Zi-Huang Cao | 2017 | Research in Astronomy and Astrophysics2017，17，10： | 1 |

| 4 | STCF conceptual design report (Volume 1): Physics & detector显示文摘The superτ-charm facility(STCF)is an electron–positron collider proposed by the Chinese particle physics community.It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5×1035 cm–2·s–1 or higher.The STCF will produce a data sample about a factor of 100 larger than that of the presentτ-charm factory—the BEPCII,providing a unique platform for exploring the asymmetry of matter-antimatter(charge-parity violation),in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions,as well as searching for exotic hadrons and physics beyond the Standard Model.The STCF project in China is under development with an extensive R&D program.This document presents the physics opportunities at the STCF,describes conceptual designs of the STCF detector system,and discusses future plans for detector R&D and physics case studies. | M.Achasov X.C.Ai L.P.An R.Aliberti Q.An X.Z.Bai Y.Bai O.Bakina A.Barnyakov V.Blinov V.Bobrovnikov D.Bodrov A.Bogomyagkov A.Bondar I.Boyko Z.H.Bu F.M.Cai H.Cai J.J.Cao Q.H.Cao X.Cao Z.Cao Q.Chang K.T.Chao D.Y.Chen H.Chen H.X.Chen J.F.Chen K.Chen L.L.Chen P.Chen S.L.Chen S.M.Chen S.Chen S.P.Chen W.Chen X.Chen X.F.Chen X.R.Chen Y.Chen Y.Q.Chen H.Y.Cheng J.Cheng S.Cheng T.G.Cheng J.P.Dai L.Y.Dai X.C.Dai D.Dedovich A.Denig I.Denisenko J.M.Dias D.Z.Ding L.Y.Dong W.H.Dong V.Druzhinin D.S.Du Y.J.Du Z.G.Du L.M.Duan D.Epifanov Y.L.Fan S.S.Fang Z.J.Fang G.Fedotovich C.Q.Feng X.Feng Y.T.Feng J.L.Fu J.Gao Y.N.Gao P.S.Ge C.Q.Geng L.S.Geng A.Gilman L.Gong T.Gong B.Gou W.Gradl J.L.Gu A.Guevara L.C.Gui A.Q.Guo F.K.Guo J.C.Guo J.Guo Y.P.Guo Z.H.Guo A.Guskov K.L.Han L.Han M.Han X.Q.Hao J.B.He S.Q.He X.G.He Y.L.He Z.B.He Z.X.Heng B.L.Hou T.J.Hou Y.R.Hou C.Y.Hu H.M.Hu K.Hu R.J.Hu W.H.Hu X.H.Hu Y.C.Hu J.Hua G.S.Huang J.S.Huang M.Huang Q.Y.Huang W.Q.Huang X.T.Huang X.J.Huang Y.B.Huang Y.S.Huang N.Hüsken V.Ivanov Q.P.Ji J.J.Jia S.Jia Z.K.Jia H.B.Jiang J.Jiang S.Z.Jiang J.B.Jiao Z.Jiao H.J.Jing X.L.Kang X.S.Kang B.C.Ke M.Kenzie A.Khoukaz I.Koop E.Kravchenko A.Kuzmin Y.Lei E.Levichev C.H.Li C.Li D.Y.Li F.Li G.Li G.Li H.B.Li H.Li H.N.Li H.J.Li H.L.Li J.M.Li J.Li L.Li L.Li L.Y.Li N.Li P.R.Li R.H.Li S.Li T.Li W.J.Li X.Li X.H.Li X.Q.Li X.H.Li Y.Li Y.Y.Li Z.J.Li H.Liang J.H.Liang Y.T.Liang G.R.Liao L.Z.Liao Y.Liao C.X.Lin D.X.Lin X.S.Lin B.J.Liu C.W.Liu D.Liu F.Liu G.M.Liu H.B.Liu J.Liu J.J.Liu J.B.Liu K.Liu K.Y.Liu K.Liu L.Liu Q.Liu S.B.Liu T.Liu X.Liu Y.W.Liu Y.Liu Y.L.Liu Z.Q.Liu Z.Y.Liu Z.W.Liu I.Logashenko Y.Long C.G.Lu J.X.Lu N.Lu Q.F.Lü Y.Lu Y.Lu Z.Lu P.Lukin F.J.Luo T.Luo X.F.Luo Y.H.Luo H.J.Lyu X.R.Lyu J.P.Ma P.Ma Y.Ma Y.M.Ma F.Maas S.Malde D.Matvienko Z.X.Meng R.Mitchell A.Nefediev Y.Nefedov S.L.Olsen Q.Ouyang P.Pakhlov G.Pakhlova X.Pan Y.Pan E.Passemar Y.P.Pei H.P.Peng L.Peng X.Y.Peng X.J.Peng K.Peters S.Pivovarov E.Pyata B.B.Qi Y.Q.Qi W.B.Qian Y.Qian C.F.Qiao J.J.Qin J.J.Qin L.Q.Qin X.S.Qin T.L.Qiu J.Rademacker C.F.Redmer H.Y.Sang M.Saur W.Shan X.Y.Shan L.L.Shang M.Shao L.Shekhtman C.P.Shen J.M.Shen Z.T.Shen H.C.Shi X.D.Shi B.Shwartz A.Sokolov J.J.Song W.M.Song Y.Song Y.X.Song A.Sukharev J.F.Sun L.Sun X.M.Sun Y.J.Sun Z.P.Sun J.Tang S.S.Tang Z.B.Tang C.H.Tian J.S.Tian Y.Tian Y.Tikhonov K.Todyshev T.Uglov V.Vorobyev B.D.Wan B.L.Wang B.Wang D.Y.Wang G.Y.Wang G.L.Wang H.L.Wang J.Wang J.H.Wang J.C.Wang M.L.Wang R.Wang R.Wang S.B.Wang W.Wang W.P.Wang X.C.Wang X.D.Wang X.L.Wang X.L.Wang X.P.Wang X.F.Wang Y.D.Wang Y.P.Wang Y.Q.Wang Y.L.Wang Y.G.Wang Z.Y.Wang Z.Y.Wang Z.L.Wang Z.G.Wang D.H.Wei X.L.Wei X.M.Wei Q.G.Wen X.J.Wen G.Wilkinson B.Wu J.J.Wu L.Wu P.Wu T.W.Wu Y.S.Wu L.Xia T.Xiang C.W.Xiao D.Xiao M.Xiao K.P.Xie Y.H.Xie Y.Xing Z.Z.Xing X.N.Xiong F.R.Xu J.Xu L.L.Xu Q.N.Xu X.C.Xu X.P.Xu Y.C.Xu Y.P.Xu Y.Xu Z.Z.Xu D.W.Xuan F.F.Xue L.Yan M.J.Yan W.B.Yan W.C.Yan X.S.Yan B.F.Yang C.Yang H.J.Yang H.R.Yang H.T.Yang J.F.Yang S.L.Yang Y.D.Yang Y.H.Yang Y.S.Yang Y.L.Yang Z.W.Yang Z.Y.Yang D.L.Yao H.Yin X.H.Yin N.Yokozaki S.Y.You Z.Y.You C.X.Yu F.S.Yu G.L.Yu H.L.Yu J.S.Yu J.Q.Yu L.Yuan X.B.Yuan Z.Y.Yuan Y.F.Yue M.Zeng S.Zeng A.L.Zhang B.W.Zhang G.Y.Zhang G.Q.Zhang H.J.Zhang H.B.Zhang J.Y.Zhang J.L.Zhang J.Zhang L.Zhang L.M.Zhang Q.A.Zhang R.Zhang S.L.Zhang T.Zhang X.Zhang Y.Zhang Y.J.Zhang Y.X.Zhang Y.T.Zhang Y.F.Zhang Y.C.Zhang Y.Zhang Y.Zhang Y.M.Zhang Y.L.Zhang Z.H.Zhang Z.Y.Zhang Z.Y.Zhang H.Y.Zhao J.Zhao L.Zhao M.G.Zhao Q.Zhao R.G.Zhao R.P.Zhao Y.X.Zhao Z.G.Zhao Z.X.Zhao A.Zhemchugov B.Zheng L.Zheng Q.B.Zheng R.Zheng Y.H.Zheng X.H.Zhong H.J.Zhou H.Q.Zhou H.Zhou S.H.Zhou X.Zhou X.K.Zhou X.P.Zhou X.R.Zhou Y.L.Zhou Y.Zhou Y.X.Zhou Z.Y.Zhou J.Y.Zhu K.Zhu R.D.Zhu R.L.Zhu S.H.Zhu Y.C.Zhu Z.A.Zhu V.Zhukova V.Zhulanov B.S.Zou Y.B.Zuo | 2024 | Frontiers of physics2024，19，1： | 0 |
| 5 | Engineering properties of the Bukit Timah Granitic residual soil in Singapore显示文摘Extensive site investigations were conducted prior to the construction of a Mass Rapid Transit project in Singapore that was predominantly in the Bukit Timah Granite(BTG)formation residual soil.This paper evaluates the engineering properties of the BTG formation residual soil based on data from 208 site investigation boreholes from four different sites.Based on the results from 2481 conventional laboratory tests and 1192 in-situ tests,this paper summarizes the engineering properties of the highly variable BTG residual soil,including conventional composition analysis,index and hydraulic properties,and strength and deformation parameters required for geotechnical analysis and design.Based on these results,the BTG formation is found to be quite heterogeneous.As the degree of weathering decreases with depth from the top of the formation,the BTG residual soil becomes sandier,with reduced silt and clay fractions.The coefficient of permeability and the compression index of the BTG residual soil vary significantly.In addition,the empirical equations relating the shear strength(index)to the standard penetration test(SPT)-N,as well as the equations and charts for determining stiffness,are proposed.These findings,together with the proposed equations or charts,can be used for design guidance of similar projects related to granitic residual soils in Singapore. | W.G.Zhang R.H.Zhang L.Han A.T.C.Goh | 2019 | Underground Space2019，4，2： | 0 |
| 6 | Orbital parameters and period variation studies of the short-period eclipsing binaries FG Sct, VZ Lib and VZ Psc显示文摘We present eight sets of new light curves for binaries FG Sct,VZ Lib and VZ Psc,which are all contact eclipsing binaries with short orbital periods.We carried out our observations from 2016 to 2017 using the 60-cm telescope administered by National Astronomical Observatories,Chinese Academy of Sciences,the Holcomb Observatory at Butler University and the SARA-CT telescope in Chile.We firstly determined the orbital parameters of FG Sct using the O-C method and obtained photometric solutions utilizing the updated W-D program.We also studied its period variation and discovered that its orbital period is decreasing at a rate of 6.39(±0.24)×10^-8 d yr-1,which was likely caused by mass transfer from the primary component to the secondary component or angular momentum interchange between the two components via magnetic interactions.For VZ Lib and VZ Psc,we simultaneously analyzed their BV RI light curves in conjunction with the published radial velocities.In order to obtain the orbital parameters of VZ Lib,we also analyzed its period variation and revised cyclic change,which could be attributed to either the light-time effect due to a tertiary companion or magnetic activity cycle mechanism.We derived the periods of the tertiary component of VZ Lib to be 48.7(±0.1) yr or magnetic cycle to be 46.9(±1.9) yr.Strong emission lines at Ca II H+K,Hα,Hβ,Hγ and Ca II IRT were detected in the LAMOST spectra of VZ Psc,which imply chromospheric activities in this binary system. | Qiang Yue Li-Yun Zhang Xian-Ming L.Han Hong-Peng Lu Liu Long Yan Yan | 2019 | Research in Astronomy and Astrophysics2019，19，7： | 0 |
| 7 | Light curve inversion of asteroid(585)Bilkis with Lommel-Seeliger ellipsoid method显示文摘The basic physical parameters of asteroids, such as spin parameters, shape and scattering parameters, can provide us with information on the formation and evolution of both the asteroids themselves and the entire solar system. In a majority of asteroids, the disk-integrated photometry measurement constitutes the primary source of the above knowledge. In the present paper, newly observed photometric data and existing data on(585) Bilkis are analyzed based on a Lommel-Seeliger ellipsoid model. With a Markov chain Monte Carlo(MCMC) method, we have determined the spin parameters(period, pole orientation)and shape(b/a, c/a) of(585) Bilkis and their uncertainties. As a result, we obtained a rotational period of 8.5738209 h with an uncertainty of 9×10-7h, and derived a pole of(136.46?, 29.0?) in the ecliptic frame of J2000.0 with uncertainties of 0.67?and 1.1?in longitude and latitude respectively. We also derived triaxial ratios b/a and c/a of(585) Bilkis as 0.736 and 0.70 with uncertainties of 0.003 and 0.03 respectively. | Ao Wang Xiao-Bin Wang Karri Muinonen Xianming L.Han Yi-Bo Wang | 2016 | Research in Astronomy and Astrophysics2016，16，12： | 0 |
