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…
COPAS: Compact Objects and the Physics of Accretion Survey I. Accreting Binaries with P < 83 Minutes
Wendy Mendoza, Liliana Rivera Sandoval, Jan Kára +9
We present the first results from the Compact Objects and the Physics of Accretion Survey (COPAS), a high-cadence photometric survey focused on the detection of accreting white dwa…
The Long-Period Radio Transient and Cataclysmic Variable ASKAP J1745-5051: Evidence for a 15,000 K White Dwarf and a Sub-Stellar Donor
Christian Knigge, Simone Scaringi, Noel Castro Segura +2
Long-period transients (LPTs) are radio sources that exhibit polarized periodic radio bursts on time-scales of minutes to hours. At least some LPTs are associated with white dwarfs…
The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149
M. Imbrogno, M. Veresvarska, Y. L. Wang +8
Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…
Multi-wavelength outburst activity from EP J174942.2-384834: a very faint X-ray transient discovered by Einstein Probe
F. Coti Zelati, A. Marino, Y. L. Wang +27
We report the discovery and multi-wavelength characterization of the Galactic transient EP J174942.2384834, first detected by the Einstein Probe during a faint X-ray outburst in…
A Systematic Search for Optical Outbursts in IPs Using ASAS-SN
Jake Mendelsohn, Simone Scaringi, Martina Veresvarska +1
Cataclysmic variables can show rapid increases in optical flux. Intermediate polars (IPs), a subset with strong magnetic fields that disrupt the inner accretion disc, have been tho…
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…
The Inner and Outer Shock Layers of Bow Shocks in Cataclysmic Variables
Krystian Ilkiewicz, Christian Knigge, Simone Scaringi +3
Bow shocks around cataclysmic variables (CVs) have traditionally been identified with a single bright optical arc. This feature has been interpreted as the bow shock formed by the…
A persistent bow shock in a diskless magnetised accreting white dwarf
Krystian Ilkiewicz, Simone Scaringi, Domitilla de Martino +9
Stellar bow shocks are formed when an outflow interacts with the interstellar medium. In white dwarfs accreting from a binary companion, outflows are associated with either strong…
The optical photometric and spectroscopic periodicities of the cataclysmic variable SRGt 062340.2-265751
J. Brink, D. A. H. Buckley, M. Veresvarska +10
We report on optical spectroscopic and photometric follow-up observations of the eROSITA discovered transient SRGt 062340.2-265751 and show that it displays the characteristics of…
