Are most detected tidal disruption events partial?

Megha Sharma, Daniel J. Price, Alexander Heger +1

During a tidal disruption event (TDE), a star loses mass due to the tidal gravitational forces of the black hole. In a partial tidal disruption event, a stellar remnant is left beh…

A benchmark for binary star interaction with a supermassive black hole in general relativity

Megha Sharma, Alexander Heger, Daniel J. Price +4

Most galaxies have supermassive black holes (SMBH) at their centres, surrounded by stars with binary systems also present in this environment. We use two schemes - post-Newtonian (…

The deci-Hz gravitational wave signal from the collapse of rotating very massive stars

Bailey Sykes, Jade Powell, Bernhard Müller +1

We calculate the gravitational wave signal from the collapse of a rotating 300 star at the upper end of the pair-instability regime. The large-scale asymmetries that deve…

Crust composition and the Shallow Heat Source in KS 1731-260

R. Jain, E. F. Brown, H. Schatz +11

The presence of a strong shallow heat source of unknown origin in accreting neutron star crusts has been inferred by analyzing X-ray observations of their cooling in quiescence. We…

Convection and the Core -mode in Proto-Compact Stars -- A detailed analysis

Pia Jakobus, Bernhard Mueller, Alexander Heger

We present a detailed analysis of the dynamics of proto-compact star (PCS) convection and the core -mode in core-collapse supernovae based on general relativistic 2D and…
