Unveiling extremely veiled T Tauri stars
G. F. Gahm, F. M. Walter, H. C. Stempels +2
Photospheric absorption lines in classical T Tauri stars (CTTS) are weak compared to normal stars. This so-called veiling is normally identified with an excess continuous emission…
Early spectral evolution of Nova Sgr 2004 (V5114 Sgr)
A. Ederoclite, E. Mason, M. Della Valle +15
We present optical and near-infrared spectral evolution of the Galactic nova V5114 Sgr (2004) during few months after the outburst. We use multi-band photometry and line intensitie…
Search for young stars among ROSAT All-Sky Survey X-ray sources in and around the R CrA dark cloud
Ralph Neuhaeuser, Fred M. Walter, Elvira Covino +6
We present the ROSAT All-Sky Survey data in a 126 deg^2 area in and around the CrA star forming region. With low-resolution spectroscopy of unidentified ROSAT sources we could find…
X-Ray Sources in Regions of Star Formation. VI. The R CrA Association as Viewed by EINSTEIN
F. M. Walter, F. J. Vrba, S. J. Wolk +2
We report on optical identifications of X-ray sources in the vicinity of the R~CrA association. We identify 11 low-mass pre-main-sequence stars as counterparts of 9 X-ray sources.…
