The updated BaSTI stellar evolution models and isochrones: II. alpha-enhanced calculations
A. Pietrinferni, S. L. Hidalgo, S. Cassisi +7
This is the second paper of a series devoted to present an updated release of the BaSTI ( a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the…
Stellar population astrophysics (SPA) with the TNG -- The Arcturus Lab
C. Fanelli, L. Origlia, E. Oliva +4
Context. High-resolution spectroscopy in the near-infrared (NIR) is a powerful tool for characterising the physical and chemical properties of cool-star atmospheres. The current ge…
The Gaia-ESO Survey: an extremely Li-rich giant in the globular cluster NGC 1261
N. Sanna, E. Franciosini, E. Pancino +16
Lithium rich stars in globular clusters are rare. In fact, only 14 have been found so far, in different evolutionary phases from dwarfs to giants. Different mechanisms have been pr…
Gaia DR2 colour-temperature relations based on infrared flux method results
A. Mucciarelli, M. Bellazzini
The ESA/Gaia mission is providing accurate and precise all-sky photometry. We combined effective temperatures derived, for a sample of dwarf and giant stars, by Gonzalez Hernandez…
Facing the problems on the determination of stellar temperatures and gravities: Galactic globular clusters
A. Mucciarelli, P. Bonifacio
We analysed red giant branch stars in 16 Galactic globular clusters, computing their atmospheric parameters both from the photometry and from excitation and ionisation balances. Th…
Lithium abundances in globular clusters
N. Sanna, E. Franciosini, E. Pancino +1
Lithium is created during the Big Bang nucleosynthesis and it is destroyed in stellar interiors at relatively low temperatures. However, it should be preserved in the stellar envel…
How stellar rotation shapes the colour magnitude diagram of the massive intermediate-age star cluster NGC 1846
Sebastian Kamann, Nate Bastian, Seth Gossage +19
We present a detailed study of stellar rotation in the massive 1.5 Gyr old cluster NGC 1846 in the Large Magellanic Cloud. Similar to other clusters at this age, NGC 1846 shows an…
