1Laser produced electromagnetic pulses: generation, detection and mitigation显示文摘This paper provides an up-to-date review of the problems related to the generation,detection and mitigation of strong electromagnetic pulses created in the interaction of high-power,high-energy laser pulses with different types of solid targets.It includes new experimental data obtained independently at several international laboratories.The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produce.The major emphasis is put on the GHz frequency domain,which is the most damaging for electronics and may have important applications.The physics of electromagnetic emissions in other spectral domains,in particular THz and MHz,is also discussed.The theoretical models and numerical simulations are compared with the results of experimental measurements,with special attention to the methodology of measurements and complementary diagnostics.Understanding the underlying physical processes is the basis for developing techniques to mitigate the electromagnetic threat and to harness electromagnetic emissions,which may have promising applications.Fabrizio Consoli Vladimir TTikhonchuk Matthieu Bardon Philip Bradford David CCarroll Jakub Cikhardt Mattia Cipriani Robert JClarke Thomas ECowan Colin NDanson Riccardo De Angelis Massimo De Marco Jean-Luc Dubois Bertr Etchessahar Alejro Laso Garcia David IHillier Ales Honsa Weiman Jiang Viliam Kmetik Josef Krása Yutong Li FredériéLubrano Paul McKenna Josefine Metzkes-Ng Alexre Poyé Irene Prencipe Piotr Ra¸czka Rol ASmith Roman Vrana Nigel CWoolsey Egle Zemaityte Yihang Zhang Zhe Zhang Bernhard Zielbauer David Neely 2020High Power Laser Science and Engineering2020,8,2:3

11On the central symmetry of the circumstellar envelope of RS Cnc显示文摘We present a phenomenological study of CO(1–0) and CO(2–1) emission from the circumstellar envelope(CSE) of the Asymptotic Giant Branch(AGB) star RS Cnc. It reveals departures from central symmetry that turn out to be efficient tools for the exploration of some of the properties of the CSE. We use a wind model including a bipolar flow with a typical wind velocity of ~8 km s-1that decreases to~2 km s-1near the equator. This wind model is used to describe Doppler velocity spectral maps obtained by merging data collected at the IRAM Plateau de Bure Interferometer and Pico Veleta single dish radio telescope. Parameters describing the wind morphology and kinematics are obtained, together with the radial dependence of the gas temperature in the domain of the CSE probed by the CO observations.Significant north-south central asymmetries are revealed by the analysis, which we quantify using a simple phenomenological description. The origin of such asymmetries is unclear.Pham Tuyet Nhung Do Thi Hoai Jan Martin Winters Pierre Darriulat Eric Grard Thibaut Le Bertre 2015Research in Astronomy and Astrophysics2015,15,5:0
12ALMA observations of the circumstellar envelope around EP Aqr显示文摘Atacama Large Millimetre/sub-millimetre Array(ALMA) observations of CO(1–0) and CO(2–1) emissions from the circumstellar envelope of the asymptotic giant branch(AGB) star EP Aqr have been made with four times better spatial resolution than previously available. They are analysed with emphasis on the de-projection in space of the effective emissivity and flux of matter using as input a prescribed configuration of the velocity field, assumed to be radial. The data are found to display an intrinsic axisymmetry with respect to an axis making a small angle with respect to the line of sight. A broad range of wind configurations, from prolate(bipolar) to oblate(equatorial) has been studied and found to be accompanied by significant equatorial emission. Qualitatively, the effective emissivity is enhanced near the equator to produce the central narrow component observed in the Doppler velocity spectra and its dependence on star latitude generally follows that of the wind velocity with the exception of an omni-present depression near the poles. In particular, large equatorial expansion velocities produce a flared disc or a ring of effective emissivity and mass loss. The effect on the determination of the orientation of the star axis of radial velocity gradients, and possibly competing rotation and expansion in the equatorial disc, is discussed. In general,the flux of matter is found to reach a broad maximum at distances of the order of 500 AU from the star.Arguments are given that may be used to favour one wind velocity distribution over another. As a result of the improved quality of the data, a deeper understanding of the constraints imposed on morphology and kinematics has been obtained.Pham Thi Tuyet Nhung Do Thi Hoai Pham Tuan-Anh Thibaut Le Bertre Pierre Darriulat Pham Ngoc Diep Nguyen Thi Phuong Nguyen Thi Thao Jan Martin Winters 2019Research in Astronomy and Astrophysics2019,19,3:0
13HⅠ emission from the red giant Y CVn with the VLA and FAST显示文摘Imaging studies with the Very Large Array(VLA) have revealed H I emission associated with the extended circumstellar shells of red giants. We analyze the spectral map obtained on Y CVn, a J-type carbon star on the Asymptotic Giant Branch. The H I line profiles can be interpreted with a model of a detached shell resulting from the interaction of a stellar outflow with the local interstellar medium.We reproduce the spectral map by introducing a distortion along a direction corresponding to the star's motion in space. We then use this fitting to simulate observations expected from the Five-hundred-meter Aperture Spherical radio Telescope(FAST), and discuss its potential for improving our description of the outer regions of circumstellar shells.Do T.Hoai Pham T.Nhung Lynn D.Matthews Eric Grard Thibaut Le Bertre 2017Research in Astronomy and Astrophysics2017,17,7:0
