The Close Binary Central Star of the Planetary Nebula PHR J1602-4127
Abstract
We are undertaking a search for binary central stars in planetary nebulae by detecting variations in brightness indicative of a binary companion. By modeling discovered binary star systems, the resulting parameters will give insight into how the binary central star interacts with its surrounding nebula. Here we announce the discovery of a close binary central star in the Planetary Nebula PHR J1602-4127. The central binary is an irradiated system with a cool companion and an orbital period of 0.29592 days. We have B, V, and R light curves from the SARA-South Telescope and orbit-resolved spectra obtained with the Gemini-South telescope. Using a binary star modeling program we have found possible parameter sets for physical values of this binary central star.
