We report on the discovery of 15 new weak-line T Tauri stars (wTTS) south of the Taurus molecular clouds based on the large database produced by the ROSAT All...
Weather Research and Forecasting prevision model as a tool to search for the best sites for astronomy: application to La Palma, Canary Islands
We present a study of the spatial variation of forecast conditions at La Palma, Canary Islands. Previsions are obtained with the Weather Research and...
WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
We present a detailed study of the large-scale shock front in Stephan's Quintet, a by-product of past and ongoing interactions. Using integral-field...
WEAVE-StePS: A stellar population survey using WEAVE at WHT
Context. The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys...
WeCAPP - Wendelstein Calar Alto pixellensing project I. Tracing dark and bright matter in M 31
We present WeCAPP, a long term monitoring project searching for microlensing events towards M 31. Since 1997 the bulge of M 31 was monitored in two different...
Weighing stars from birth to death: mass determination methods across the HRD
The mass of a star is the most fundamental parameter for its structure, evolution, and final fate. It is particularly important for any kind of stellar...
Welcome to the Twilight Zone: The Mid-infrared Properties of Post-starburst Galaxies
We investigate the optical and Wide-field Survey Explorer (WISE) colors of “E+A” identified post-starburst galaxies, including a deep analysis of 190 post...
