Multiple populations along the asymptotic giant branch of the globular cluster M 4
C. Lardo, M. Salaris, A. Savino +3
Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with…
Statistical errors and systematic biases in the calibration of the convective core overshooting with eclipsing binaries. A case study: TZ Fornacis
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
We attempt to constrain the initial helium abundance, the age and the efficiency of the convective core overshooting of the binary system TZ Fornacis. Our main aim is in pointing o…
Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld
E. Pian, L. Tomasella, E. Cappellaro +37
Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed th…
Gaia data release 1, the photometric data
F. van Leeuwen, D. W. Evans, F. De Angeli +91
Context. This paper presents an overview of the photometric data that are part of the first Gaia data release. Aims. The principles of the processing and the main characteristics o…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. VIII. Preliminary Public Catalog Release
M. Soto, A. Bellini, J. Anderson +14
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GO-13297) has been specifically designed to complement the existing F606W and F814W observations of…
Ne and Na ejecta from intermediate-mass stars: The impact of the new LUNA rate for Ne(p,)Na
A. Slemer, P. Marigo, D. Piatti +36
We investigate the impact of the new LUNA rate for the nuclear reaction NeNa on the chemical ejecta of intermediate-mass stars, with particular focus on the ther…
