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…
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…
