Abstract

In 2007, Antipin, Sokolovsky, and Ignatieva discovered the first eclipsing binary with a Type II Cepheid component in our Galaxy, ASAS182612. We present the analysis of ASAS182612’s pulse and orbital periods from 2007 to 2014 using B, V, R, and I filters. The pulsation and orbital periods were found to be 4.1622 ± .0003 days and 51.366 ± .025 days, respectively. The angular acceleration of the pulse period was determined to be 1.1E-6 ± 1E-7 rad/day².
