Open clusters (OCs) are crucial for studying the formation and evolution of the Galactic disc. The lack of a large number of OCs analysed homogeneously hampers...

We examine the light curves of over 2700 stars observed in long cadence by the Kepler spacecraft as part of the Guest Observer program. Most of these stars are...

Dwarf irregular (dIr) galaxies are frequent targets of young stellar populations research. But less attention has been devoted to their intermediate-age and old...

The paper presents CCD photometry for stars in three fields centered on the old open cluster NGC 188 and in four fields on the intermediate-age cluster NGC 7789...

The Near Infrared Spectrograph and Photometer (NISP) is one of the instruments on board the EUCLID mission. The focal plane array (FPA) consists of 16 HAWAII...

Of the thousands of exoplanets known, only three disintegrating planets have been identified. These disintegrating planets appear to have tails of dusty...

During the post-AGB phase the dust shell detaches from the central star and dust temperatures varies between 100 and 200 K. In order to study the onset of photo...
