Rapid bursts of magnetically gated accretion in the intermediate polar V1025 Cen
Colin Littlefield, Jean-Pierre Lasota, Jean-Marie Hameury +5
Magnetically gated accretion has emerged as a proposed mechanism for producing extremely short, repetitive bursts of accretion onto magnetized white dwarfs in intermediate polars (…
Searching for Diamagnetic Blob Accretion in the 74 day K2 Observation of V2400 Ophiuchi
Andrew Langford, Colin Littlefield, Peter Garnavich +3
Since its discovery in 1995, V2400 Ophiuchi (V2400 Oph) has stood apart from most known intermediate polar cataclysmic variables due to its proposed magnetic field strength (9-27 M…
An accreting white dwarf displaying fast transitional mode switching
S. Scaringi, D. de Martino, D. H. Buckley +6
Accreting white dwarfs are often found in close binary systems with orbital periods ranging from tens of minutes to several hours. In most cases, the accretion process is relativel…
Spectroscopy of the Proposed White Dwarf Pulsar ASASSN-V J205543.90+240033.5
R. Mark Wagner, Peter Garnavich, John R. Thorstensen +2
We obtained spectra of ASASSN-V J205543.90+240033.5 (J2055), a system that shows photometric variations similar to the white dwarf (WD) pulsar AR Scorpii (Kato et al. arXiv:2109.03…
Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070
Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49
How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…
Quasi-periodic oscillations in the TESS light curve of TX Col, a diskless intermediate polar on the precipice of forming an accretion disk
Colin Littlefield, Simone Scaringi, Peter Garnavich +4
One of the fundamental properties of an intermediate polar is the dynamical nature of the accretion flow as it encounters the white dwarf's magnetosphere. Many works have presumed…
Exploring the tilted accretion disc of AQ Men with TESS
Krystian Ilkiewicz, Simone Scaringi, James M. C. Court +8
AQ Men is a nova-like variable which is presumed to have a tilted, precessing accretion disc. Grazing eclipses in this system have been speculated to be useful in exploring the geo…
Confirmation of a Second Propeller: A High-Inclination Twin of AE~Aquarii
Peter Garnavich, Colin Littlefield, R. M. Wagner +4
For decades, AE Aquarii (AE Aqr) has been the only cataclysmic variable star known to contain a magnetic propeller: a persistent outflow whose expulsion from the binary is powered…
