Formation Channels of Magnetars

Magnetars are neutron stars (NSs) with strong magnetic fields and are associated with various high-energy astrophysical phenomena. However, their formation channels remain an open question. In this work, we explore potential magnetar formation channels and quantify their contributions using population synthesis simulations, considering both single-star and isolated binary system evolution. By varying model parameters, we compare the effects of various evolution processes on magnetar formation. Additionally, we study the delay times and kick velocities across all formation channels and analyze the orbital properties and companion types of surviving magnetar binaries.
