The distribution of warm molecular gas (1000-3000 K), traced by the near-IR H2 2.12 μm line, has been imaged with a resolution

The SuperWASP cameras are wide-field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the Sutherland Station of the South African Astronomical Observatory. Each instrument has a field of view of some 482 deg2 with an angular scale of 13.7" pixel-1, and is capable of delivering

The Balmer lines of four A Ia-supergiants (spectral type A0 to A3) and fourteen B Ia and Ib-supergiants (spectral type B0 to B3) in the solar neighbourhood are analyzed by means of NLTE unified model atmospheres to determine the properties of their stellar winds, in particular their wind momenta. As in previous work for O-stars (Puls et al. cite

The analysis of the X-ray data for a sample of 51 LINER nuclei with available X-ray Chandra imaging is reported. Our aim was to investigate the physical mechanisms which power LINER nuclear activity. The use of multiwavelenght information at radio, UV, optical HST and X-ray lead us to conclude that at least 60% of the LINERs are hosting a low

We observe Eris, one of the largest trans-Neptunian objects, in the 300 - 2480 nm range with X-Shooter, the first second-generation instrument for the ESOVery Large Telescope, and compare the newly obtained spectra with those available in the literature. The large spectra coverage and high resolving power ( / ' 5000) of X-Shooter allow us to study
