No Period Change in Two Long-Period AM CVn Binaries

Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25

Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…

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 DBL Survey I: discovery of 34 double-lined double white dwarf binaries

James Munday, Ingrid Pelisoli, P. E. Tremblay +8

We present the first discoveries of the double-lined double white dwarf (DBL) survey that targets over-luminous sources with respect to the canonical white dwarf cooling sequence a…

ASASSN-14dx: A cataclysmic variable harbouring a massive pulsating white dwarf

Pasi Hakala, Ingrid Pelisoli, Boris T. Gaensicke +5

We present the results of our study of ASASSN-14dx, a previously known but poorly characterised cataclysmic variable (CV). The source was observed as part of an ongoing high-time-r…

Follow-up on three poorly studied AM CVn stars

Amornrat Aungwerojwit, Boris T. Gaensicke, E. Breedt +12

We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV1440, and SDSSJ183131.63+420220.2. Analysing time-series photometry…

Cataclysmic variables from Sloan Digital Sky Survey -- V (2020-2023) identified using machine learning

Keith Inight, Boris T. Gänsicke, Axel Schwope +16

SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of 504 cataclysmic variables (CVs) and CV candida…
