IR spectroscopy of pre-cataclysmic binaries
C. Tappert, B. T. Gaensicke, R. E. Mennickent
We have taken near-infrared (JHK) spectroscopic data of a sample of pre-CVs, in order to examine them for signatures of nuclear evolution. Here we present preliminary results for t…
The Characteristics of Magnetic CVs in the Period Gap
G. Tovmassian, S. Zharikov, R. Mennickent +1
We have observed several magnetic cataclysmic variables located in the range between 2 and 3 hours, known as the period gap. This work was prompted by the recent discovery of RX J1…
Light Curve Analysis of Be Star Candidates in the Small Magellanic Cloud
R. E. Mennickent, G. Pietrzynski, W. Gieren
The recent discovery, based on a search of public OGLE data, of Be star candidates in the Small Magellanic Cloud showing spectacular photometric variations (Mennickent et al. 2002)…
Identification of the donor in GRS 1915+105
J. Greiner, M. J. McCaughrean, J. G. Cuby +2
We report on the results of medium-resolution spectroscopy of GRS 1915+105 in the H and K band using the 8m VLT at ESO. We clearly identify absorption bandheads from CO12 and CO13.…
