This communication presents a family of spectrographs designed for the European Solar Telescope. They can operate in four different configurations: a long slit...

Comparisons of visible/NIR and FIR/submm data are investigated on several spatial scales in and around the OMC-1, OMC-2 and OMC-3 star-forming regions in Orion...

Light curves for sixty WASP-12 b's transits observed in 2010-2012 are given. Data were collected with 0.5-2.6-m telescopes located in thirteen observatories...

We conducted two multi-site campaigns for two previously poorly-studied rapidly oscillating Ap (roAp) stars, HD122970 and HD99563. In January-June 1998, we...

Results from a new multi-wavelength evolutionary synthesis model including the γ-ray line emission from various radioactive isotopes (26Al, 60Fe) are presented...

Since its discovery in 1992, the superluminal X-ray transient GRS 1915+105 has been extensively observed in an attempt to understand its behaviour. We present...
