  • Radial velocities of HBHA 4705-03

    Results of photometric and spectroscopic studies for the new eclipsing cataclysmic variable star HBHA 4705-03 with an orbital period of 0.1718 days are presented.
  • Gaia/IPHAS catalogue of Ha-excess sources

    We present a catalogue of point-like H{alpha}-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and...
  • DW Cnc H{alpha} and HeI RV curves

    We present extensive radial velocity observations of the intermediate polar DW Cnc during its 2018-2019 low state. We show that the 86 min signal associated with the orbital...
  • Wide astrometric companions with Gaia DR2

    Evolution of close binaries often proceeds through the common envelope stage. The physics of the envelope ejection (CEE) is not yet understood, and several mechanisms were...
  • Disentangling cataclysmic variables in Gaia DR2

    Cataclysmic Variables (CVs) are interacting binaries consisting of at least three components that control their colour and magnitude. Using Gaia we here investigate the...
  • Study of spiral density waves in CVs

    Spiral density waves are thought to be excited in the accretion discs of accreting compact objects, including cataclysmic variable stars (CVs). Observational evidence has been...
  • Outburst catalogue of cataclysmic variables

    The Outburst Catalogue contains a wide variety of observational properties for 722 dwarf nova-type (DN) cataclysmic variables (CVs) and 309 CVs of other types from the Catalina...
  • H{alpha} velocity curves of IM Eri

    We report photometric detections of orbital and superorbital signals, and negative orbital sidebands, in the light curves of the nova-like cataclysmic variables AQ Mensae and IM...
  • Hidden population of AM CVns in the SDSS

    We present the latest results from a spectroscopic survey designed to uncover the hidden population of AM Canum Venaticorum (AM CVn) binaries in the photometric database of the...
  • Census of blue stars in SDSS DR8

    We present a census of the 12060 spectra of blue objects ((g-r)0<-0.25) in the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8). As part of the data release, all of the...
  • Collinder 261 Chandra sources & optical counterparts

    We present the first X-ray study of Collinder 261 (Cr261), which at an age of 7Gyr is one of the oldest open clusters known in the Galaxy. Our observation with the Chandra X-Ray...
  • Photometry of polar CV* 1RXS J173006.4+033813

    We report the discovery of 1RXS J173006.4+033813, a polar cataclysmic variable with a period of 120.21 minutes. The white dwarf primary has a magnetic field of B=42^+6^-5_MG and...
  • ChaMPlane deep galactic bulge survey. I.

    We have carried out a deep X-ray and optical survey with Chandra and HST of low-extinction regions in the Galactic bulge. Here we present the results of a search for...
  • 2006-2016 CCD photometry of V723 Cassiopeia

    We present photometric data of the classical nova, V723 Cas (Nova Cas 1995), over a span of 10 years (2006 through 2016) taken with the 0.9 m telescope at Lowell Observatory,...
  • A VLA survey of magnetic CVs. I. The data

    The Jansky Very Large Array was used to observe 121 magnetic cataclysmic variables (MCVs). We report radio detections of 18 stars. Thirteen are new radio sources, increasing the...
  • Radial velocities of 29 cataclysmic variables

    We report follow-up spectroscopy of 29 cataclysmic variables from the Sloan Digital Sky Survey (SDSS), 22 of which were discovered by SDSS and seven of which are previously...
  • Spectroscopy and photometry of CV candidates

    The Catalina Real Time Survey (CRTS) has found over 500 cataclysmic variable (CV) candidates, most of which were previously unknown. We report here on follow-up spectroscopy of...
  • H{alpha} radial velocities of AM Her

    We present observations in the red region of the spectrum of the magnetic cataclysmic variable prototype AM Her during its 2005 low state. We confirm the unexpected structure of...
  • Quiescent CV TUVO-21acq SALT spectrum

    We present the discovery of TUVO-21acq, a new transient which we detected in the UV using data from the UVOT aboard Swift. We detected two separate outbursts and used the UVOT...
  • AT 2018bwo light curves

    Luminous red novae (LRNe) are astrophysical transients associated with the partial ejection of a binary system's common envelope (CE) shortly before its merger. Here we present...
