Evidence for Solar-like Oscillations in Arcturus (Alpha Boo)
Alon Retter, Timothy R. Bedding, Derek Buzasi +1
Observations of the red giant Arcturus (Alpha Boo) obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a baseline of 19 successive days in 20…
Detection of negative superhumps in a LMXRB -- an end to the long debate on the nature of V1405 Aql (X1916-053)
A. Retter, Y. Chou, T. Bedding
Two similar periodicities (3001 and 3028 s) are known from the X-ray and optical light curves of V1405 Aql, a low mass X-ray Binary (LMXRB). Two competing models have been offered…
Does TV Col Have the longest Recorded Positive Superhumps?
A. Retter, C. Hellier, T. Augusteijn +1
Re-examination of extensive photometric data of TV Col reveals evidence for a permanent positive superhump. Its period (6.4 h) is 16 percent longer than the orbital period and obey…
The transition phase in Nova Muscae 1998, the dust formation in classical novae and a possible link to intermediate polar systems
A. Retter, W. Liller, G. Garradd
We present results of continuous CCD photometry of Nova Muscae 1998 during 17 nights obtained mainly during the transition phase in the light curve of the young nova. We discovered…
New evolutionary scenarios for short orbital period CVs
A. Retter, T. Naylor
We suggest new evolutionary scenarios for non-magnetic short orbital period CVs. The first model is the analogy of the `hibernation scenario' or the `modern hibernation scenario'.…
Novae Crossing the Thermal Stability Line
A. Retter, T. Naylor, E. M. Leibowitz
A method, based on the disc instability model, for testing the thermal stability of Cataclysmic Variables (CVs), is presented. It is shown that the border line between thermal stab…
