Sunrise is a solar telescope with an aperture of 1 m, and is dedicated for spectropolarimetric measurements in the visible and the near UV. The total wavelength...
High-resolution Spectroscopy of Faint Stars with Transiting Planets
We present a series of studies based on high-resolution UVES/VLT spectroscopy of several faint stars for which a transit by a giant planet has been detected...
We use UVES spectroscopy of PB 6 to study the variation of its physical conditions as a function of position including: temperature, density, chemical...
High-resolution transmission spectroscopic studies of hot and ultra-hot Jupiters.
Hot and ultra-hot Jupiters, gas-giant planets with short orbital period, and hot, extended atmospheres, are most suitable objects in order to study the chemical...
The rapidly variable Seyfert 1 galaxy NGC 4151 will be the subject of an intensive monitoring campaign with IUE, Rosat, GRO, ASCA and ground-based telescopes in...
