Long suspected on theoretical grounds and supported by tantalising observational evidence, the connection between supernovae and gamma-ray bursts was definitely...

Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show...

Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

The Kepler spacecraft is providing photometric time series with micromagnitude precision for thousands of variable stars. The continuous time-series of...

All the elements from carbon to uranium present in the Solar System were produced by hundreds to thousands of stars belonging to different stellar generations...

Luminous Blue Variables (LBVs) are massive stars caught in a post-main sequence phase, during which they are losing a significant amount of mass. Given the...

Massive stars lose mass through powerful, radiatively driven stellar winds. Building on the original "CAK" model for steady, spherical winds driven by line...

The current databases of empirical star spectra for modelling single-aged stellar populations (SSPs) generally do not chemically characterize their stars...

In this work we have tried to verify what types of bulges are the descendants and the precursors of the bulges with blue colors observed at intermediate z...
