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

Sean J. Gunderson, Walter W. Golay, Jackson Codd +8

We present a multiwavelength analysis of the star Oph C, covering X-ray, optical, near-infrared, and radio observations to test for the presence of interferometrically-detected…

Chandra/HETG and NuSTAR Observations of V750 Ara, a Cas-type Star

David P. Huenemoerder, Sean J. Gunderson, Richard Ignace +6

We present 197 ks HETG and 95 ks NuSTAR spectra of the Cas-type object V750 Ara. The high-resolution X-ray spectra show that the target is similar to other objects of this cla…

X-ray Polarimetry of Accreting White Dwarfs: A Case Study of EX Hydrae

Sean J. Gunderson, Swati Ravi, Herman L. Marshall +5

We present the first first X-ray polarization measurements of a white dwarf, the intermediate polar EX Hya. We measured significant polarization only in the 2 -- 3 keV energy band…

A Multiwavelength View of Oph I: Resolving the X-ray Source Between A and B

Sean J. Gunderson, Jackson Codd, Walter W. Golay +12

We present a multiwavelength analysis of the central stellar pair of Oph, components A and B. Using recent high-resolution \textit{Chandra X-ray Observatory} observations, we d…

Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years

Noel D. Richardson, Micaela Henson, Emma P. Lieb +23

Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is ca…

Chandra HETG X-ray Spectra and Variability of Aqr, a Cas-type Be star

David P. Huenemoerder, Pragati Pradhan, Claude R. Canizares +7

High-resolution X-ray spectra of Aqr, a Cas-type star, obtained with the Chandra/HETG grating spectrometer, revealed emission lines of H-like ions of Mg, Si, S, and Fe, a…
