Description
Neutron stars represent one of the most diverse and dynamic populations in high-energy astrophysics, manifesting as radio pulsars, millisecond pulsars, magnetars, X-ray binaries, and other exotic subclasses. In recent years, time-domain surveys have revealed unexpected connections between these classes and some of the most energetic transients in the Universe, including fast radio bursts (FRBs), gamma-ray bursts (GRBs), and certain supernovae (SNe). This talk provides a comprehensive overview of the “neutron star zoo,” emphasizing the importance and distributions of physical parameters such as magnetic field, spin, age, and environment that drive their observational phenomenology. I will review how different neutron star classes emerge from similar evolutionary pathways and how they can transition between states. Special focus will be placed on observational and theoretical links between young magnetars and core-collapse SNe, between compact object formation and GRBs, and between magnetar bursts and FRBs.
