Analysis of Pulsating Components in the Eclipsing Binary Systems LT Herculis, RZ Microscopii, LY Puppis,V632 Scorpii, and V638 Scorpii

摘要

Eclipsing binary stars are especially valuable for studies of stellar evolution. If pulsating components are also present then the stellar interior can be studied using asteroseismology techniques. We present photometric data and the analysis of the δ Scuti pulsations that we have discovered in five eclipsing binary systems. The systems are: LT Herculis, RZ Microscopii, LY Puppis, V632 Scorpii,and V638 Scorpii. The dominant pulsation frequencies range from 13 to 29 cycles per day with semi-amplitudes of 4 to 20 millimagnitudes.
