A Survey of Eclipsing Binary Stars in the Eastern Spiral Arm of M31
Ian Todd, Don Pollacco, Ian Skillen +3
Results of an archival survey are presented using B-band imaging of the eastern spiral arm of M31. Focusing on the eclipsing binary star population, a matched-filter technique has…
Identification of 13 DB + dM and 2 DC + dM binaries from the Sloan Digital Sky Survey
E. J. M. van den Besselaar, G. H. A. Roelofs, G. A. Nelemans +2
We present the identification of 13 DB + dM binaries and 2 DC + dM binaries from the Sloan Digital Sky Survey (SDSS). Before the SDSS only 2 DB + dM binaries and 1 DC + dM binary w…
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…
First stars VI - Abundances of C, N, O, Li, and mixing in extremely metal-poor giants. Galactic evolution of the light elements
M. Spite, R. Cayrel, B. Plez +11
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances in 35 extremely metal-poor halo giants (22 stars have [Fe/H]<-3.0) usi…
