We have carried out a spectroscopic study of asteroid 65 Cybele in the 2 - 4 μm and 5 - 14 μm regions, using NASA's IRTF and Spitzer Space Telescope...

A population of small main-belt asteroid pairs (MBAs) residing on very similar heliocentric orbits have been found and studied recently (Vokrouhlicky and...

We use asteroid differential photometry gathered in the past decades together with the Gaia stellar catalogue (as photometric standards) to obtain relative...

The growing volume of astronomical data produced by telescopic facilities presents significant challenges and extraordinary opportunities for the scientific...

The global parameters of the Pleiades cluster are derived from the comparison of observed and computed frequencies of six multi-periodic delta Scuti stars. The...

The age of a star cannot be measured but only inferred from observational quantities related to age. For stars in the red-giant phase, classical methods such as...

The region of the hot end of the main-sequence is hosting pulsating stars of different types and flavours. Pulsations are not only observed for Slowly pulsating...
