Unveiling the birth and evolution of the HII region Sh2-173
S. Cichowolski, G. A. Romero, M. E. Ortega +2
Based on a multiwavelength study, the ISM around the HII region Sh2-173 has been analyzed. The ionized region is clearly detected in the optical and in the radio continuum images.…
Post Common Envelope Binaries from SDSS. V: Four eclipsing white dwarf main sequence binaries
S. Pyrzas, B. T. Gänsicke, T. R. Marsh +7
We identify SDSS011009.09+132616.1, SDSS030308.35+005444.1, SDSS143547.87+373338.5 and SDSS154846.00+405728.8 as four eclipsing white dwarf plus main sequence (WDMS) binaries from…
A New Window of Exploration in the Mass Spectrum: Strong Lensing by Galaxy Groups in the SL2S
M. Limousin, R. Cabanac, R. Gavazzi +21
The existence of strong lensing systems with Einstein radii (Re) covering the full mass spectrum, from ~1-2" (produced by galaxy scale dark matter haloes) to >10" (produced by gala…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Direct evidence of a sub-stellar companion around CT Cha
T. O. B. Schmidt, R. Neuhäuser, A. Seifahrt +5
In our ongoing search for close and faint companions around T Tauri stars, we found a very faint (Ks=14.9mag, Ks_0=14.4mag) object, just ~2.67" northwest of the Chamaeleon star-for…
Post Common Envelope Binaries from SDSS - III. Seven new orbital periods
A. Rebassa-Mansergas, B. T. Gaensicke, M. R. Schreiber +11
We present follow-up spectroscopy and photometry of 11 post common envelope binary (PCEB) candidates identified from multiple Sloan Digital Sky Survey (SDSS) spectroscopy in an ear…
