The High Energy X-ray Probe (HEX-P): A New Window into Neutron Star Accretion
R. M. Ludlam, C. Malacaria, E. Sokolova-Lapa +15
Accreting neutron stars (NSs) represent a unique laboratory for probing the physics of accretion in the presence of strong magnetic fields ( G). Additionally, the ma…
Constraining the evolution of the unstable accretion disk in SMC X-1 with NICER
McKinley C. Brumback, Georgios Vasilopoulos, Joel B. Coley +2
Neutron star high mass X-ray binaries with superorbital modulations in luminosity host warped inner accretion disks that occult the neutron star during precession. In SMC X-1, the…
An Extreme Black Hole in the Recurrent X-ray Transient XTE J2012+381
Paul A. Draghis, Jon M. Miller, McKinley C. Brumback +3
The black hole candidate XTE J2012+381 underwent an outburst at the end of 2022. We analyzed 105 NICER observations and 2 NuSTAR observations of the source during the outburst. The…
Monitoring observations of SMC X-1's excursions (MOOSE)-II: A new excursion accompanies spin-up acceleration
Chin-Ping Hu, Kristen C. Dage, William I. Clarkson +11
SMC X-1 is a high-mass X-ray binary showing superorbital modulation with an unstable period. Previous monitoring shows three excursion events in 1996--1998, 2005--2007, and 2014--2…
Revealing the spectral state transition of the Clocked Burster, GS 1826-238 with NuSTAR StrayCats
S. B. Yun, B. W. Grefenstette, R. M. Ludlam +4
We present the long term analysis of GS 1826-238, a neutron star X-ray binary known as the "Clocked Burster", using data from NuSTAR StrayCats. StrayCats, a catalogue of NuSTAR str…
