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…
A hot Jupiter transiting a mid-K dwarf found in the pre-OmegaCam Transit Survey
J. Koppenhoefer, R. P. Saglia, L. Fossati +13
We describe the pre-OmegaTranS project, a deep survey for transiting extra-solar planets in the Carina region of the Galactic Disk. In 2006-2008 we observed a single dense stellar…
A photometric study of the nova-like variable TT Arietis with the MOST satellite
N. Vogt, A. -N. Chené, A. F. J. Moffat +7
Variability on all time scales between seconds and decades is typical for cataclysmic variables (CVs). One of the brightest and best studied CVs is TT Ari, a nova-like variable whi…
New companions in the stellar systems of DI Cha, Sz 22, CHXR 32, and Cha Halpha 5 in the Cha I star-forming region
T. O. B. Schmidt, N. Vogt, R. Neuhäuser +2
The star-forming regions in Chamaeleon (Cha) are among the nearest (distance ~165 pc) and youngest (age ~2 Myrs) conglomerates of recently formed stars and among the ideal targets…
The hunt for old novae
C. Tappert, N. Vogt, L. Schmidtobreick +1
We inform on the progress of our on-going project to identify and classify old classical novae, using deep UBVR photometry and subsequent spectroscopy for a proper candidate confir…
