We study the mid-egress eclipse timing data gathered for the cataclysmic binary HU Aquarii during the years 1993-2014. The (O-C) residuals were previously...
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - IV. Helium content and relative age of multiple stellar populations within NGC 6352
In this paper, we combine Wide Field Camera3/UVIS F275W, F336W, and F438W data from the `UV Legacy Survey of Galactic Globular Clusters: Shedding Light on Their...

The Hubble Space Telescope UV Legacy Survey of Galactic globular clusters - IX. The Atlas of multiple stellar populations
We use high-precision photometry of red-giant-branch (RGB) stars in 57 Galactic globular clusters (GCs), mostly from the `Hubble Space Telescope (HST) UV Legacy...
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - XVII. Public Catalogue Release
In this paper, we present the astrophotometric catalogues of 56 globular clusters and one open cluster. Astrometry and photometry are mainly based on images...
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. VIII. Preliminary Public Catalog Release
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GO-13297) has been specifically designed to complement the existing F606W and...
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XV. The Dynamical Clock: Reading Cluster Dynamical Evolution from the Segregation Level of Blue Straggler Stars
The parameter A +, defined as the area enclosed between the cumulative radial distribution of blue straggler stars (BSSs) and that of a reference population, is...
The Hα environment of T Tauri resolved by speckle interferometry.
T Tauri, the prototype of a class of low-mass pre-main sequence stars, was observed with the 3.6m Canada-France-Hawaii telescope (CFHT) and the CP40 photon...
The IACOB project . III. New observational clues to understand macroturbulent broadening in massive O- and B-type stars
Context. The term macroturbulent broadening is commonly used to refer to a certain type of non-rotational broadening affecting the spectral line profiles of O-...
