Star Formation Histories of Ultra-Faint Dwarf Galaxies: environmental differences between Magellanic and non-Magellanic satellites?
Elena Sacchi, Hannah Richstein, Nitya Kallivayalil +18
We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Trian…
The HST large programme on omega Centauri -- IV. catalogue of two external fields
M. Scalco, A. Bellini, L. R. Bedin +10
In the fourth paper of this series, we present -- and publicly release -- the state-of-the-art catalogue and atlases for the two remaining parallel fields observed with the Hubble…
A new photometric and dynamical study of the eclipsing binary star HW Virginis
S. B. Brown-Sevilla, V. Nascimbeni, L. Borsato +12
A growing number of eclipsing binary systems of the "HW Vir" kind (i. e., composed by a subdwarf-B/O primary star and an M dwarf secondary) show variations in their orbital period,…
A PSF-based Approach to TESS High quality data Of Stellar clusters (PATHOS) -- IV. Candidate exoplanets around stars in open clusters: frequency and age-planetary radius distribution
D. Nardiello, M. Deleuil, G. Mantovan +7
The knowledge of the ages of stars hosting exoplanets allows us to obtain an overview on the evolution of exoplanets and understand the mechanisms affecting their life. The measure…
Hunting for intermediate-mass black holes in globular clusters: an astrometric study of NGC 6441
Maximilian Häberle, Mattia Libralato, Andrea Bellini +6
We present an astrometric study of the proper motions (PMs) in the core of the globular cluster NGC 6441. The core of this cluster has a high density and observations with current…
