Extremely red stellar objects revealed by IPHAS
N. J. Wright, R. Greimel, M. J. Barlow +13
We present photometric analysis and follow-up spectroscopy for a population of extremely red stellar objects extracted from the point-source catalogue of the INT Photometric H-Alph…
Newly Discovered Cataclysmic Variables from the INT/WFC Photometric H alpha Survey of the Northern Galactic Plane
A. R. Witham, C. Knigge, A. Aungwerojwit +7
We report the discovery of 11 new cataclysmic variable (CV) candidates by the Isaac Newton Telescope (INT) Photometric H alpha Survey of the northern Galactic plane (IPHAS). Three…
HST/FGS Parallaxes of AM CVn Stars and Astrophysical Consequences
G. H. A. Roelofs, P. J. Groot, G. F. Benedict +5
We present absolute parallaxes and relative proper motions for five AM CVn stars, which we obtained using the Fine Guidance Sensors on board the Hubble Space Telescope. Our paralla…
DE CVn: A bright, eclipsing red dwarf - white dwarf binary
E. J. M. van den Besselaar, R. Greimel, L. Morales-Rueda +10
Close white dwarf - red dwarf binaries must have gone through a common-envelope phase during their evolution. DE CVn is a detached white dwarf - red dwarf binary with a relatively…
Kinematics of the ultra-compact helium accretor AM Canum Venaticorum
G. H. A. Roelofs, P. J. Groot, G. Nelemans +2
We report on the results from a five-night campaign of high-speed spectroscopy of the 17-minute binary AM Canum Venaticorum, obtained with the 4.2-m William Herschel Telescope on L…
GEMINI spectroscopy of the ultra-compact binary candidate V407 Vul
D. Steeghs, T. R. Marsh, S. C. C. Barros +5
We present time-resolved spectroscopy of the optical counterpart to the proposed ultra-compact binary system V407 Vul (=RX J1914.4+2456). Our Gemini spectra resolve the 9.48 minute…
