The orbital ephemeris of the classical nova RR Pictoris: presence of a third body?
N. Vogt, M. R. Schreiber, F. -J. Hambsch +4
The ex-nova RR Pic presents a periodic hump in its light curve which is considered to refer to its orbital period. Analyzing all available epochs of these hump maxima in the litera…
Life after eruption - III. Orbital periods of the old novae V365 Car, AR Cir, V972 Oph, HS Pup, V909 Sgr, V373 Sct and CN Vel
C. Tappert, L. Schmidtobreick, N. Vogt +1
We present time-series photometric and spectroscopic data for seven old novae. They are used to derive the orbital period for the systems V365 Car (5.35 h), AR Cir (5.14 h), V972 O…
Transits and starspots in the WASP-19 planetary system
Jeremy Tregloan-Reed, John Southworth, C. Tappert
We have developed a new model for analysing light curves of planetary transits when there are starspots on the stellar disc. Because the parameter space contains a profusion of loc…
Discovery of Halpha satellite emission in a low state of the SW Sextantis star BB Doradus
L. Schmidtobreick, P. Rodriguez-Gil, K. S. Long +3
BB Dor was observed during its low state state in 2009. Signatures of both binary components are revealed in the average optical spectrum; no signature of accretion is observed. Na…
Post-common-envelope binaries from SDSS. XIII: Mass dependencies of the orbital period distribution
M. Zorotovic, M. R. Schreiber, B. T. Gänsicke +11
Post-common-envelope binaries (PCEBs) consisting of a white dwarf (WD) and a main-sequence secondary star are ideal systems to constrain models of common-envelope (CE) evolution. U…
Search for brown-dwarf like secondaries in cataclysmic variables II
R. E. Mennickent, M. P. Diaz, C. Tappert
We have examined VTL/ISAAC 1-2.5 $\umu$m spectroscopy of a sample of short orbital period cataclysmic variables which are candidates for harboring substellar companions. We provide…
