We present here the results of the second multisite campaign of the STEPHI (STEllar PHotometry International) network. This three weeks rapid photometry...

We present near-infrared (JKs) time series data of the Large Magellanic Cloud (LMC) cluster Reticulum. The observing strategy and data reduction (DAOPHOTII...

Synthetic horizontal branch (HB) stars in globular clusters, when computed on the basis of HB evolutionary tracks and pulsation theory constraints, furnish the...

The ZZ Ceti stars form a class of variable white dwarfs: the hydrogen dominated atmosphere ones, which do pulsate in an instability strip in the effective...

Old-aged stellar distance indicators are present in all Galactic structures (halo, bulge, disk) and in galaxies of all Hubble types and, thus, are immensely...

Spectrograms of the variable star 48 Librae, taken near the last expected minimum, have been examined for irregularities of the shell line profiles. The...

We present V-band CCD photometry, UBVRI photopolarimetry, and near simultaneous JHK photometry of 3C 345 during a renewed outburst in spring of 1992, which...

The authors present simultaneous UBVRI and infrared JHKL light curves of the short-period RS CVn system ER Vul, and study both the mean level and depths of...

The Delta Scuti variable 63 Her was observed during 21 nights at two observatories (Observatorio del Teide, Tenerife Island, Spain and Observatorio Astronomico...
