Accretion onto compact objects, such as black holes and neutron stars, is a fundamental process in astrophysics, powering some of the most luminous objects in the universe. In X-ray binaries, the accretion of matter from a companion star onto the compact object leads to the emission of intense X-ray radiation. While the general framework of accretion is well understood, there exist peculiar and enigmatic fast flaring activities exhibited by different types of X-ray binaries, which challenge our current understanding of these systems.
In this seminar, I will delve into the diverse flaring behaviors observed in various X-ray binaries, highlighting their extreme properties. I will then discuss the possible mechanisms that have been proposed to explain these events. By exploring them, we can gain insights into the underlying physics of accretion and the behavior of matter in extreme environments.
Finally, I will outline the future prospects for studying these enigmatic events, including the potential for new discoveries with upcoming X-ray missions.
