X-ray transients

X-ray transients are astronomical objects or events that produce sudden, intense bursts of X-ray radiation, which then fade away over time. They often involve compact objects like neutron stars or black holes that pull in material from a companion star. This process creates hot, energetic conditions that emit X-rays. When the accretion rate (material falling onto the compact object) varies, the X-ray brightness can change dramatically, causing transient (short-lived) outbursts. These events help scientists study extreme physics and the behavior of matter under intense gravity.
