| Title: | Investigation Of The Photometric and Spectroscopic Variations In Be/X-Ray Binaries |
| Abstract: | In this work we present the results of approximately 6 years (2005-2011) monitoring of several Be stars in Be/X-ray binary systems. The photometric data, obtained by Robotic Optical Transient Experiment (ROTSE IIId), state that Be stars show mainly three different types of variations; i) a long-term variation with a time scale of 3-5 years, ii) a mid-term variation lasting weeks or months, iii) a short term variation occurred in days or hours. Using the archival RXTE/ASM observations, the analogies of the X-ray and the optical light-curves are investigated. We also present the optical spectroscopic observations of these systems, taken with the Russian Turkish 1.5 m Telescope (RTT150), to point out whether any correlation exists with the optical brightness variations. |
