New Observations of Close Eclipsing Binary Systems with δ Scuti Pulsations

摘要

In this paper we present the detection of δ Scuti-type pulsations in three close eclipsing binary systems (EV Ori, FO Ori, X Tri) as part of a photometric observing campaign of fourteen such systems. These observations were done as part of an ongoing effort to find such objects as they are of great value for checking theoretical models of stellar characteristics against empirically determined parameters.
