The life cycle of stars and their planets from the high energy perspective
Lia Corrales, Keivan G. Stassun, Tim Cunningham +19
One of the key research themes identified by the Astro2020 decadal survey is Worlds and Suns in Context. The Advanced X-ray Imaging Satellite (AXIS) is a proposed NASA APEX mission…
Quiet, but not silent: Uncovering quiescent state properties of two transient High Mass X-ray binaries
Gayathri Raman, Varun, Pragati Pradhan +1
We present the first set of broadband spectral and timing studies of two transient X-ray pulsars, MXB 0656-072 and MAXI J1409-619 using NuSTAR observations conducted during quiesce…
Stable Coronal X-Ray Emission Over Twenty Years of XZ Tau
Steven M. Silverberg, Hans Moritz Guenther, Pragati Pradhan +3
XZ Tau AB is a frequently observed binary YSO in the Taurus Molecular Cloud; XZ Tau B has been classified as an EXOr object. We present new Chandra/HETG-ACIS-S observations of XZ T…
Survey of X-rays from Massive Stars Observed at High Spectral Resolution with Chandra
Pragati Pradhan, David P. Huenemoerder, Richard Ignace +2
Identifying trends between observational data and the range of physical parameters of massive stars is a critical step to the still-elusive full understanding of the source, struct…
The RS Oph outburst of 2021 monitored in X-rays with NICER
Marina Orio, Keith Gendreau, Morgan Giese +19
The 2021 outburst of the symbiotic recurrent nova RS Oph was monitored with the Neutron Star Interior Composition Explorer Mission (NICER) in the 0.2-12 keV range from day one afte…
Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415
Pragati Pradhan, Carlo Ferrigno, Biswajit Paul +11
Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object ca…
