X-Ray Flares/Bursts from GRS 1915+105 and the Two Component Accretion Flow
We present results of our analysis of a set of RXTE/PCA observations of X-ray flares/bursts with burst cycle ranging from 30 to 1300 s from the Galactic X-ray transient source GRS 1915+105 during last four years. These flares/bursts can be classified into four types: 1) regular bursts with short burst phase of ∼ 20 s (R1), 2) regular bursts with short quiescent phase of ∼ 20 s (R2), 3) long regular bursts (R3) with burst cycle ≥ 1000 s, and 4) irregular bursts (IR). For all the observed bursts, the duration of the quiescent phase is inversely proportional to the square of the QPO frequency (2–10 Hz).
