Description
In this talk, we will discuss our efforts in numerically modelling viscous effects in neutron stars (NSs) using the recently proposed first-order dissipative hydrodynamics framework by Bemfica, Disconzi, Noronha and Kovtun (known as the BDNK framework). We first demonstrate that under a simplified set up, stable evolutions of spherically symmetric NSs can be achieved in 1+1 spacetime, from which we can compare the predictions of the viscous theory with the perfect fluid model. We then discuss our progress in generalising our setup to 3+1 spacetimes.
