The X-ray and optical emission of the intermediate polar Swift J0614.0+1709
Nikita Rawat, Domitilla De Martino, David A. H. Buckley +5
We present the first detailed X-ray and optical study of the intermediate polar Swift J0614.0+1709 based on a pointed XMM-Newton observation complemented by long-term optical photo…
On the frequency-dependent time lags of the intermediate polar V709 Cas
Zackery A. Irving, Noel Castro Segura, Diego Altamirano +9
Cataclysmic variables (CVs) are binary systems in which a white dwarf (WD) primary accretes material from a late-type secondary, typically via a disc. To date, only six CVs, all of…
phoptic -- a Python package for reducing astronomical images
Zackery A. Irving, Noel Castro Segura, Diego Altamirano +6
Publicly-available photometry pipelines make astronomical data reduction accessible to non-experts, reduce the margin for human error, and enable reproducible reduction. In many ca…
A Catalogue of Orbital Periods of Cataclysmic Variables and Candidates from TESS Observations
Meryem K. Dağ, Simone Scaringi, Kieran O'Brien +21
We present a systematic analysis of 2544 cataclysmic variable systems and related candidates observed by the Transiting Exoplanet Survey Satellite (TESS), with the aim of compiling…
DW Cnc: a micronova with a negative superhump and a flickering spin
M. Veresvarska, S. Scaringi, C. Littlefield +15
Magnetic accreting white dwarfs in cataclysmic variables have been known to show bursts driven by different physical mechanisms; however, the burst occurrence is much rarer than in…
X-Ray, UV, and Optical Observations of Proxima Centauri's Stellar Cycle
B. J. Wargelin, S. H. Saar, Z. A. Irving +3
Proxima Cen (GJ 551; dM5.5e) is one of only about a dozen fully convective stars known to have a stellar cycle, and the only one to have long-term X-ray monitoring. A previous anal…
Discovery of Persistent Quasi-Periodic Oscillations in Accreting White Dwarfs: A New Link to X-ray Binaries
M. Veresvarska, S. Scaringi, C. Knigge +8
Almost all accreting black hole and neutron star X-ray binary systems (XRBs) exhibit prominent brightness variations on a few characteristic time-scales and their harmonics. These…
Stellar Cycles in Fully Convective Stars and a New Interpretation of Dynamo Evolution
Zackery A. Irving, Steven H. Saar, Bradford J. Wargelin +1
An dynamo, combining shear and cyclonic convection in the tachocline, is believed to generate the solar cycle. However, this model cannot explain cycles in fast rotators (with…
