SDSS J124058.03-015919.2: A new AM CVn star with a 37-minute orbital period
G. H. A. Roelofs, P. J. Groot, T. R. Marsh +3
We present high time resolution VLT spectroscopy of SDSS J124058.03-015919.2, a new helium-transferring binary star identified in the Sloan Digital Sky Survey. We measure an orbita…
Photometric Variability in the Faint Sky Variability Survey
L. Morales-Rueda, P. J. Groot, T. Augusteijn +3
The Faint Sky Variability Survey (FSVS) is aimed at finding photometric and/or astrometric variable objects between 16th and 24th mag on time-scales between tens of minutes and yea…
SDSS J1240-01: A New AM CVn Candidate from the Sloan Digital Sky Survey
G. Roelofs, P. Groot, D. Steeghs +1
We report on the discovery of a new AM CVn candidate from the Sloan Digital Sky Survey, Data Release 1. Our first spectroscopic follow-up in the optical is presented and discussed…
A search for the optical and near-infrared counterpart of the accreting millisecond X-ray pulsar XTE J1751-305
P. G. Jonker, G. Nelemans, Z. Wang +14
We have obtained optical and near-infrared images of the field of the accreting millisecond X-ray pulsar XTE J1751-305. There are no stars in the 0.7'' error circle (0.7'' is the o…
The Faint Sky Variability Survey I: An Overview
P. J. Groot, P. M. Vreeswijk, M. E. Everett +1
The Faint Sky Variability Survey is aimed at finding variable objects in the brightness range between 17th and 25th magnitude on timescales between tens of minutes and years with p…
