A Multiwavelength View of $\rho$ Oph II: Disentangling the Variability of the Multi-Star Component C

We present a multiwavelength analysis of the star $\rho$ Oph C, covering X-ray, optical, near-infrared, and radio observations to test for the presence of interferometrically-detected cool star companions. The X-ray observations from Chandra, XMM-Newton, and NuSTAR show flare-like events lasting minutes or days in time...

Direct spectroscopic observation of matter falling onto a compact stellar object

GX 301–2 is an accreting x-ray pulsar with a massive hypergiant companion WRAY 977, embedded within a dense circumstellar environment. We report on detected redshifted hydrogen- and helium-like iron lines, together with transitions from lower ionization states, observed with XRISM/Resolve during an x-ray flare. Notably...
