Modelling telluric line spectra in the optical and infrared with an application to VLT/X-Shooter spectra
N. Rudolf, H. M. Günther, P. C. Schneider +1
Earth's atmosphere imprints a large number of telluric absorption and emission lines on astronomical spectra, especially in the near infrared, that need to be removed before analys…
X-raying circumstellar material around young stars
P. C. Schneider, H. M. Günther
Young stars are surrounded by copious amounts of circumstellar material. Its composition, in particular its gas-to-dust ratio, is an important parameter. However, measuring this ra…
The nature of the 2014-2015 dim state of RW Aur revealed by X-ray, optical, and NIR observations
P. C. Schneider, H. M. Günther, J. Robrade +7
The binary system RW Aur consists of two classical T~Tauri stars (CTTSs). The primary recently underwent its second observed major dimming event (mag). We present new,…
X-ray to NIR emission from AA Tauri during the dim state - Occultation of the inner disk and gas-to-dust ratio of the absorber
P. C. Schneider, K. France, H. M. Günther +5
AA Tau is a well-studied, nearby classical T Tauri star, which is viewed almost edge-on. A warp in its inner disk periodically eclipses the central star, causing a clear modulation…
YSOVAR: Mid-Infrared Variability in NGC 1333
L. M. Rebull, J. R. Stauffer, A. M. Cody +17
As part of the Young Stellar Object VARiability (YSOVAR) program, we monitored NGC 1333 for ~35 days at 3.6 and 4.5 um using the Spitzer Space Telescope. We report here on the mid-…
YSOVAR: Mid-infrared Variability Among YSOs in the Star Formation Region GGD 12-15
Scott J. Wolk, H. Moritz Günther, Katja Poppenhaeger +9
We present an IR-monitoring survey with the Space Telescope of the star forming region GGD 12-15. Over 1000 objects were monitored including about 350 objects within the…
YSOVAR: mid-infrared variability of young stellar objects and their disks in the cluster IRAS 20050+2720
K. Poppenhaeger, A. M. Cody, K. R. Covey +12
We present a time-variability study of young stellar objects in the cluster IRAS 20050+2720, performed at 3.6 and 4.5 micron with the Spitzer Space Telescope; this study is part of…
