	1	Photometric and Spectroscopic Study of Two Low Mass Ratio Contact Binary Systems:CRTS J225828.7-121122 and CRTSJ030053.5+230139显示文摘The study reports photometric and spectroscopic observations of two recently recognized contact binary systems.Both systems show total eclipses and analysis of the light curves indicates both have very low mass ratios of less than 0.3.We derive absolute parameters from color and distance based calibrations and show that,although both have low mass ratios,they are likely to be in a stable orbit and unlikely to merge.In other respects,both systems have characteristics similar to other contact binaries with the secondary larger and brighter than their main sequence counterparts and we also find that the secondary is considerably denser than the primary in both systems.

	2	Photometric analysis of two extreme low mass ratio contact binary systems显示文摘Multi-band photometry and light curve analysis for two newly recognized contact binary systems,TYC 6995-813-1 and NSVS 13602901,are presented.Both were found to be of extreme low mass ratios 0.11 and 0.17,respectively.The secondary components of both systems show evidence of considerable evolution with elevated densities as well as both luminosity and radii well above their main sequence counterparts.Even in the absence of significant spot activity,at least one of the systems,TYC 6995-813-1,displays features of magnetic and chromospheric activity.TYC 6995-813-1 is also determined to be a potential merger candidate with its current separation near the theoretical instability separation.
