We propose to carry out full-synthesis (12-h) HI ATCA observations of 8 bright Blue Compact Dwarf Galaxies (BCDGs), for which we have already got interesting results. Some are apparently isolated, others belong to galaxy groups. We want to estimate the distribution of the HI in each BCDG and its surrounding, looking for independent HI clouds or

We obtained very deep and high spatial resolution near-infrared images of the Orion Trapezium Cluster using the Multi-Conjugate Adaptive Optics Demonstrator (MAD) instrument at the VLT. The goal of these observations has been to search for objects at the very low-mass end of the IMF down to the planetary-mass regime. Three fields in the innermost

The interaction pulsation/mass loss takes different aspects. Pulsations can trigger mass loss as in LBVs and Miras; on the other hand, mass loss can modify the driving conditions within the stars. But the most spectacular aspect is the effect on stellar models which, in turn, opens a royal way to asteroseismology to test physical conditions inside

In ATel #1815 we erroneously associated the globular cluster M31GC J004234+405709 (Bol 117) with object s1-1 from Williams et al. (2006, ApJ 643, 356). Bol 117 is not associated with any previously catalogued X-ray source, so the Chandra observation we report on in ATel #1815 is the first recorded detection of X-ray activity from Bol 117. The

Context: In the past few years, a new class of high mass X-ray binaries (HMXRB) has been claimed to exist, the supergiant fast X-ray transients (SFXT). These are X-ray binary systems with a compact companion orbiting a supergiant star which show very short and bright outbursts in a series of activity periods overimposed on longer quiescent periods
