Revised Light Elements of 78 Southern Eclipsing Binary Systems

摘要

Since 2011, members of Variable Stars South have undertaken intensive time series observations and analysis of eclipsing binary systems, most of which are south of declination -40°. Many of them have not been observed in detail since their discovery 50 to 80 years ago. New or revised light elements are presented here for 60 systems and revised O-C values for a further 18 systems. A pulsating component has been discovered in four of the binary systems:RZ Mic, V632 Sco, V638 Sco, and LT Her.
