| Abstract: | We present the results of a suite of numerical simulations to study partial tidal disruption events (TDEs) of white dwarfs (WDs) in off-equatorial planes in
intermediate mass spinning (Kerr) black hole backgrounds. We carry out this analysis for both parabolic and eccentric WD orbits and also
take into account possible initial WD spins. Our objective here is to quantify the differences in variables like the mass of the self-bound core,
the peak fallback rate of debris and gravitational wave signature in off-equatorial orbits compared to equatorial ones. The analysis is carried out using a hybrid
numerical scheme, one which involves integrating the exact Kerr geodesics while adopting a Newtonian formalism for the stellar
fluid dynamics, justified by our choice of simulation parameters. We find that the physics of TDEs in off-equatorial orbits
present several interesting and novel features due to black hole spin, which in some cases enhances when coupled with the rotation
of the WD. However, numerical values of observable quantities in TDEs involving off-equatorial orbits cannot possibly distinguish between such orbits
from equatorial ones. We further comment on the genericness of our results and argue that these should extend to a general TDE scenario involving
a spinning BH. |
