Title: GRS 1915, Cause of Heartbeat Variation
Caption: This sequence of four illustrations shows the black hole in GRS 1915 and the inner part of the disk surrounding it. The first three illustrations show material in the inner disk being pushed away from the black hole by radiation pressure. The disk gets increasingly brighter and hotter in these three illustrations until it disintegrates, as shown in the fourth illustration. The inner part of the disk then refills from material farther away from the black hole and the cycle begins again.
