We report on a rapid fading of GX 339-4 to its lowest ever observed X-ray flux level. In response to the recent report of the start of an outburst of GX 339-4...
The rapid fading of V1647 Orionis: the sudden end of a FUor-type eruption?
The young eruptive star V1647 Ori started a rapid fading in October 2005 and now is only 1 mag above the pre-outburst level. Colour changes indicate that the...
The Rapid Growth of the Fingertips of Preplanetary Nebula CRL618
HST images taken over a time span of 11 years show that the tips of its bright optical fingers have proper motions exceeding 1". At the presumed distance of 0.9...
The rare decay $t o c gamma$ in the General 2HDM type III
We consider the branching ratio for the process $t o c gamma$ in the context of the General Two Higgs Doublet Model type III. We find that taking into account...
The asymptotic giant branch (AGB) is formed by low- and intermediate-mass stars (0.8 M_{⊙} M 8 M_{⊙}) in their last nuclear-burning phase, when they develop...
The European Solar Telescope (EST) will be equipped with a MCAO system to provide an excellent correction within one arcminute field of view (FOV). A prototype...
