Stellar wind signatures in sdB stars?
U. Heber, P. F. L. Maxted, T. R. Marsh +2
Subdwarf B (sdB) stars form the blue end of the horizonal branch (EHB). Their peculiar atmospheric abundance patterns are due to diffusion processes. However, diffusion models fail…
A 6.3-h superhump in the cataclysmic variable TV Columbae: the longest yet seen
A. Retter, C. Hellier, T. Augusteijn +5
We present results from a two week multi-longitude photometric campaign on TV Col held in 2001 January. The data confirm the presence of a permanent positive superhump found in re-…
Understanding the LMXB X2127+119 in M15
Zach Ioannou, L. van Zyl, T. Naylor +4
We present HST UV observations of the high-inclination low mass X-ray binary AC211 (X2127+119), which is located in the globular cluster M15 (NGC 7078). We have discovered a CIV P…
Simultaneous Optical and X-ray Observations of Flares and Rotational Modulation on the RS CVn Binary HR 1099 (V711 Tau) from the MUSICOS 1998 Campaign
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of the H, H, He {\sc i} D, Na {\sc i} D,D doublet and the Ca {\sc ii} H & K lines for the RS CVn system…
Infrared stellar populations in the central parts of the Milky Way galaxy
Jacco Th. van Loon, G. F. Gilmore, A. Omont +7
Near- and mid-IR survey data from DENIS and ISOGAL are used to investigate the structure and formation history of the inner 10 degree (1.4 kpc) of the Milky Way galaxy. Synthetic b…
New subdwarf B star periods
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +1
Subdwarf B (sdB) stars are thought to be helium burning stars with low mass hydrogen envelopes. Several evolutionary paths have been proposed to explain the formation of these syst…
