A plethora of new R Coronae Borealis stars discovered from a dedicated spectroscopic follow-up survey
P. Tisserand, G. C. Clayton, M. S. Bessell +7
It is increasingly suspected that the rare R Coronae Borealis (RCB) stars - hydrogen-deficient and carbon-rich supergiant stars - are the products of mergers of CO/He white-dwarf b…
NSV 1907 - A new eclipsing, nova-like cataclysmic variable
Stefan Hümmerich, Rainer Gröbel, Franz-Josef Hambsch +6
NSV 1907, formerly listed as an irregular variable in variability catalogues, was classified as an Algol-type eclipsing binary in the Catalina Surveys Periodic Variable Star Catalo…
Cataclysmic Variables from the Catalina Real-time Transient Survey
A. J. Drake, B. T. Gaensicke, S. G. Djorgovski +10
We present 855 cataclysmic variable candidates detected by the Catalina Real-time Transient Survey (CRTS) of which at least 137 have been spectroscopically confirmed and 705 are ne…
A new bright eclipsing hot subdwarf binary from the ASAS and SuperWASP surveys
V. Schaffenroth, S. Geier, H. Drechsel +5
We report the discovery of a bright (V=11.6 mag) eclipsing hot subdwarf binary of spectral type B with a late main sequence companion from the All Sky Automated Survey (ASAS 102322…
V1820 Orionis : an RR Lyrae star with strong and irregular Blazhko effect
Pierre de Ponthiere, Franz-Josef Hambsch, Tom Krajci +2
The Blazhko effect in V1820 Orionis and its period were reported for the first time by Wils et al. (2006) from a data analysis of the Northern Sky Variability Survey. The results o…
New light curves and ephemeris for the close eclipsing binary V963 PER
Andrew P. Odell, Patrick Wils, Clarissa Dirks +4
We have obtained CCD photometry in 2010-11 of V963 Per (=GSC3355 0394), which is a recently identified close binary star with unequal eclipse depths. The seven new eclipse timings…
