Modern observations of Hubble's first-discovered Cepheid in M31
M. Templeton, A. Henden, W. Goff +9
We present a modern ephemeris and modern light curve of the first-discovered Cepheid variable in M31, Edwin Hubble's M31-V1. Observers of the American Association of Variable Star…
Extensive Photometry of V1838 Aql during the 2013 Superoutburst
J. EchevarrÃa, E. de Miguel, J. V. Hernández Santisteban +15
We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A c…
Accretion-disc precession in UX Ursae Majoris
E. de Miguel, J. Patterson, D. Cejudo +25
We report the results of a long campaign of time-series photometry on the nova-like variable UX Ursae Majoris during 2015. It spanned 150 nights, with ~1800 hours of coverage on 12…
The helium-rich cataclysmic variable SBSS 1108+574
P. J. Carter, D. Steeghs, E. de Miguel +12
We present time-resolved spectroscopy and photometry of the dwarf nova SBSS 1108+574, obtained during the 2012 outburst. Its quiescent spectrum is unusually rich in helium, showing…
The intermediate polar cataclysmic variable GK Persei 120 years after the nova explosion: a first dynamical mass study
A. Ãlvarez-Hernández, M. A. P. Torres, P. RodrÃguez-Gil +15
We present a complete dynamical study of the intermediate polar and dwarf nova cataclysmic variable GK Per (Nova Persei 1901) based on a multi-site optical spectroscopy and -ban…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
