X-ray emission mechanisms in accreting white dwarfs

K. L. Page, A. W. Shaw

In this chapter we consider the processes which can lead to X-ray emission from different types of cataclysmic variable stars (CVs). CVs are semi-detached, binary star systems wher…

High resolution X-ray spectroscopy of V4641 Sgr during its 2020 outburst

A. W. Shaw, J. M. Miller, V. Grinberg +7

We observed the Galactic black hole X-ray binary V4641 Sgr with the high resolution transmission gratings on Chandra during the source's 2020 outburst. Over two epochs of Chandra g…

Magnetically-gated accretion model: application to short bursts in the intermediate polar V1223 Sgr

J. -M. Hameury, J. -P. Lasota, A. W. Shaw

Some intermediate polars show outbursts that are much shorter than those observed in normal dwarf novae, and whose origin has remained unelucidated for a long time. We examine here…

Hitting a New Low: The Unique 28 h Cessation of Accretion in the TESS Light Curve of YY Dra (DO Dra)

Katherine L. Hill, Colin Littlefield, Peter Garnavich +6

We present the Transiting Exoplanet Surveying Satellite (TESS) light curve of the intermediate polar YY Draconis (YY Dra, also known as DO Dra). The power spectrum indicates that w…

Investigating the low-flux states in six Intermediate Polars

Ava E. Covington, Aarran W. Shaw, Koji Mukai +30

We present optical photometry of six intermediate polars that exhibit transitions to a low-flux state. For four of these systems, DW Cnc, V515 And, V1223 Sgr and RX J2133.7+5107, w…

Classifying IGR J18007-4146 as an intermediate polar using XMM and NuSTAR

Benjamin M. Coughenour, John A. Tomsick, Aarran W. Shaw +5

Many new and unidentified Galactic sources have recently been revealed by ongoing hard X-ray surveys. A significant fraction of these have been shown to be the type of accreting wh…
