Impact of spin on the accretion disk response to a Type I X-ray burst

Accretion disks of neutron stars can be heavily irradiated by Type I X-ray bursts, which significantly alter the disk structure. Previous work simulated the time-dependent impact of the burst on the disk for a nonspinning neutron star. Here, we study the impact of spin on the burst-disk interaction through relativistic, hydrodynamic simulations. With the code Cosmos++, we run two-dimensional time-dependent simulations featuring a thin accretion disk, a burst with a peak luminosity of 10³⁸ erg s^-1, and a prograde spin with a spin parameter of a = 0.2. Our work shows how the spin affects the response of the disk to the burst.
