Context. Spatially resolved maps of stellar populations and nebular emission are key tools for understanding the physical properties and evolutionary stages of...

Context. The relative abundance of the dust grain types in the interstellar medium is directly linked to physical quantities that trace the evolution of...

Gamma-ray bursts (GRBs) have been proposed as a tool for studying star formation in the Universe, so it is crucial to investigate whether their host galaxies...

We use the Spitzer Wide-area InfraRed Extragalactic Legacy Survey (SWIRE) to explore the specific star formation activity of galaxies and their evolution near...

A new technique to perform speckle interferometric measurements at J, H, K, L and M wavelengths is described. The time-averaged spatial frequency power spectrum...

Spectroscopy of asteroids can be diagnostic of their surface composition and other properties such as internal structure. The European Space Agency's Gaia...

We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE...

Aims:We present an analysis of high resolution spectra in the J band of five ultra cool dwarfs from M6 to L0. Methods: We make use of a new ab initio water...

Context. Barium stars are peculiar red giants characterized by an overabundance of the elements synthesized in the slow neutron-capture nucleosynthesis (s...
