Title: Stars and Compact Objects in AGN Disks: From Stellar Evolution to Transients
Abstract: The disks of Active Galactic Nuclei (AGNs) have emerged as intriguing environments for the evolution of stars and the compact objects they leave behind. The extreme densities of these disks, combined with gravitational and hydrodynamic torques exerted by the gas, can drive evolutionary pathways for main-sequence stars and compact objects that differ substantially from those in typical galactic environments. Well-known transient phenomena, such as long and short gamma-ray bursts, may acquire distinctive properties when they occur within AGN disks, while new channels for transient and compact-object formation may also emerge. In particular, processes such as the accretion-induced collapse of neutron stars into black holes may occur frequently in these environments. I will discuss how the unique physical conditions of AGN disks can reshape stellar evolution and compact object demographics, and explore their implications for the transient and gravitational wave universe.
