Behavior of long term interval of state a in GRS 1915+105

We analyzed X-ray light curves of a unique black hole binary in our Galaxy, GRS 1915+105. We used Rossi X-ray Timing Explorer (RXTE) data between 2007-2008 observations, during which GRS 1915+105 was mostly in its low intensity state. We obtained a total of 93 data with various variability patterns....

Description
Summary:We analyzed X-ray light curves of a unique black hole binary in our Galaxy, GRS 1915+105. We used Rossi X-ray Timing Explorer (RXTE) data between 2007-2008 observations, during which GRS 1915+105 was mostly in its low intensity state. We obtained a total of 93 data with various variability patterns. In this work, we only focused on those data (45 observation data) with low intensity (less than 10,000 counts/s) and without complex variability patterns, known as State A. Previous studies on state A were limited to those occur sporadically due to the lack of observation data since, most of the time, GRS 1915+105 stays at high intensity state. We aimed to study the behavior of long term interval of state A in GRS 1915+105. Similar to the previous studies, we used color-color diagram for our analysis after correcting for the background. We also considered the absorption effect of the interstellar medium which is dominant below 10 keV. In general, the obtained results are in good agreement with the previous studies. However, there are some data that show different behavior which need further studies.
