Extragalactic Large-Scale Structures behind the Southern Milky Way. IV. Redshifts Obtained with MEFOS
Patrick A. Woudt, Renee C. Kraan-Korteweg, Veronique Cayatte +2
Abbreviated: As part of our efforts to unveil extragalactic large-scale structures behind the southern Milky Way, we here present redshifts for 764 galaxies in the Hydra/Antlia, Cr…
SDSS J161033.64-010223.3: A second Cataclysmic Variable with a Non-radially Pulsating Primary
Patrick A. Woudt, Brian Warner
We find from high speed photometry of the Sloan Digital Survey cataclysmic variable candidate SDSS J161033.64-010223.3 that it has a double humped modulation, which is probably orb…
AM CVn stars in the UCT CCD CV survey
Patrick A. Woudt, Brian Warner
High speed photometry of the helium-transferring binary ES Cet - taken over a two-year period (2001 October - 2003 October) - shows a very stable photometric period of 620.211437 +…
Accretion in Cataclysmic Variable stars
Brian Warner, Patrick A. Woudt
We consider accretion onto the white dwarfs in cataclysmic variables in relation to nova eruptions, dwarf nova outbursts, hibernation and non-radial oscillations.
Pulsating White Dwarfs in Cataclysmic Variables: The Marriage of ZZ Cet and Dwarf Nova
Brian Warner, Patrick A. Woudt
There are now four dwarf novae known with white dwarf primaries that show large amplitude non-radial oscillations of the kind seen in ZZ Cet stars. We compare the properties of the…
The new AM CVn star in Hydra
Patrick A. Woudt, Brian Warner
High speed photometry of the new AM CVn star in Hya (previously known as SN2003aw), spectroscopically identified by Chornock & Filippenko, shows it to have a superhump period of 20…
