Visible photometry of the RS CVn system AR Lac is presented. We find some interesting features in the light curves. Also a possible oscillation with period 1.05...

Analysis of bulges to redshifts of up to z=1 have provided ambiguous results as to whether bulges as a class are old structures akin to elliptical galaxies or...

At 04:08:54 UT on 2007 October 25, the Burst Alert Telescope on-board Swift detected GRB 071025 and performed a rapid slew to the GRB location, beginning...

The decay of a sunspot region was studied using high resolution white-light pictures. The photometric and geometric parameters of a light-bridge showing...

An increasing number of observations over the last years have shown the existence of distinct sub-populations in many (maybe all) globular clusters and...
