The Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields including Galactic studies...

Through the observational study of stellar pulsations, the internal structure of stars can be probed and theoretical models can be tested. The main sequence γ...

KIC 6761539 is one of many fast rotating γ Doradus - δ Scuti hybrid pulsators. A search for possible regularities in the frequency spectrum is performed and a...

The age of a star cannot be measured but only inferred from observational quantities related to age. A wellknown stellar age greatly impacts our understanding...

Several kiloparsec-scale X-ray jets have now been discovered with the Chandra X-ray Observatory, extending up to ~50 kpc (projected distance) from the active...

We present a kinematic analysis of the double-barred early-type galaxy NGC 357. The radial velocity and velocity dispersion profiles along both the nuclear bar...

Poster presented at the conference "Galactic bars: driving and decoding galaxy evolution", 3-7 july 2023 in Granada.

Field OB stars are a crucial probe of star formation in extreme conditions. Properties of massive stars formed in relative isolation can distinguish between...

The luminosity function is not only crucial to know stellar density distribution in space, and thus to know the structure of the Galaxy, but it allows the...
