Optical and Near-Infrared Spectroscopy of the L Subdwarf SDSS J125637.13-022452.4
Adam J. Burgasser, Soeren Witte, Christiane Helling +3
Red optical and near-infrared spectroscopy are presented for SDSS J125637.13-022452.4, one of only four L subdwarfs reported to date. These data confirm the low-temperature, metal-…
Observation and modelling of dusty, low gravity L, and M dwarfs
Andreas Seifahrt, Christiane Helling, Adam J. Burgasser +6
Observational facilities allow now the detection of optical and IR spectra of young M- and L-dwarfs. This enables empirical comparisons with old M- and L- dwarfs, and detailed stud…
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…
