The IPHAS Catalogue of Halpha Emission Line Sources in the Northern Galactic Plane
A. R. Witham, C. Knigge, J. E. Drew +5
We present a catalogue of point-source Halpha emission line objects selected from the INT/WFC Photometric H Survey of the Northern Galactic Plane (IPHAS). The catalogue covers t…
Initial Data Release from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
E. A. Gonzalez-Solares, N. A. Walton, R. Greimel +47
The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in H-alpha, r' and i' filters, with the Wide Field Camera (WFC)…
The long-period AM CVn star SDSS J155252.48+320150.9
G. H. A. Roelofs, P. J. Groot, D. Steeghs +2
The Sloan Digital Sky Survey has been instrumental in obtaining a homogeneous sample of the rare AM CVn stars: mass-transferring binary white dwarfs. As part of a campaign of spect…
The population of AM CVn stars from the Sloan Digital Sky Survey
G. H. A. Roelofs, G. Nelemans, P. J. Groot
The AM Canum Venaticorum stars are rare interacting white dwarf binaries, whose formation and evolution are still poorly known. The Sloan Digital Sky Survey provides, for the first…
An evolutionary study of the pulsating subdwarf B eclipsing binary PG1336-018 (NY Vir)
H. Hu, G. Nelemans, R. Østensen +3
The formation of subdwarf B (sdB) stars is not well understood within the current framework of stellar single and binary evolution. In this study, we focus on the formation and evo…
On the orbital periods of the AM CVn stars HP Librae and V803 Centauri
G. H. A. Roelofs, P. J. Groot, G. Nelemans +2
We analyse high-time-resolution spectroscopy of the AM CVn stars HP Librae and V803 Centauri, taken with the New Technology Telescope (NTT) and the Very Large Telescope (VLT) of th…
