Theoretical Analysis of the RX J0209.6−7427 X-Ray Spectrum during a Giant Outburst

The Astrophysical Journal Letters
We model the spectral formation occurring in the binary X-ray pulsar (XRP) RX J0209.6−7427 during the 2019 super-Eddington outburst. Using a theoretical model previously developed by the authors, we are able to produce spectra that closely resemble the ...

From Feast to Famine: A Systematic Study of Accretion onto Oblique Pulsars with 3D GRMHD Simulations

The Astrophysical Journal Letters
Disk-fed accretion onto neutron stars can power a wide range of astrophysical sources ranging from X-ray binaries, to accretion-powered millisecond pulsars, ultraluminous X-ray sources, and gamma-ray bursts.

Detection of the Optical Counterpart of the Transient ULX NGC 300 ULX-1: A Nascent Black Hole-neutron Star Binary?

The Astrophysical Journal
The endpoints of massive star evolution are poorly known, especially those in interacting binary systems containing compact objects, such as neutron stars or black holes (BHs).
