CCD Photometry Using Multiple Comparison Stars [PDF]
Journal of Astronomy and Space Sciences, 2004 The accuracy of CCD observations obtained at the Korean 1.8 m telescope has been studied. Seventeen comparison stars in the vicinity of the cataclysmic variable BG CMi have been measured.

VLA Observations of the AE Aqr-type Cataclysmic Variable LAMOST J024048.51+195226.9 [PDF]
Astronomical Journal, 2021 AE Aqr was until recently the only known magnetic cataclysmic variable (MCV) containing a rapidly spinning (33.08 s) white dwarf (WD). Its radio emission is believed to be a superposition of synchrotron-emitting plasmoids, because it has a positive ...

VY Sculptoris stars as magnetic cataclysmic variables [PDF]
Astronomy & Astrophysics, 2002 AbstractWe show that VY Scl stars must be magnetized in order to account for the absence of outbursts during their low and intermediate states. Absence of outbursts during low states requires only rather low magnetic moments but in systems in which the drops and rises of luminosity are slower than it takes for the accretion disc to adjust viscously to ...

IM Normae: The Death Spiral of a Cataclysmic Variable? [PDF]
Astrophysical Journal, 2020 We present a study of the orbital light curves of the recurrent nova IM Normae since its 2002 outburst. The broad “eclipses” recur with a 2.46 hr period, which increases on a timescale of 1.28(16) × 106 yr.

ASAS J071404+7004.3 -- a close, bright nova-like cataclysmic variable with gusty winds [PDF]
, 2021 Despite being bright ($V=12$) and nearby ($d=212$ pc) ASAS J071404+7004.3 has only recently been identified as a nova-like cataclysmic variable. We present time-resolved optical spectroscopy obtained at the Isaac Newton Telescope together with $\textit ...

An Evenly Spaced LSST Cadence for Rapidly Variable Stars
The Astrophysical Journal Supplement Series, 2023 Stars exhibit a bewildering variety of rapidly variable behaviors ranging from explosive magnetic flares to stochastically changing accretion to periodic pulsations or rotation.

Accretion in Cataclysmic Variable Stars [PDF]
, 2005 We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.

CCD-PHOTOMETRY OF CATACLYSMIC VARIABLE ES DRA IN 2001
Odessa Astronomical Publications, 2017 On the base of our 34-day photometry of ES Dra we found its ∼ 20 d light variations with amplitude of 1m.6 and suggest this star could belong to the nova-like subclass of cataclysmic variable stars.
