The Gaia grid of spectro-photometric standard stars
Nicoletta Sanna, Elena Pancino, Giuseppe Altavilla +2
We describe the preliminary results of a ground-based observing campaign aimed at building a grid of approximately 200 spectro-photometric standard stars (SPSS), with an internal $…
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…
HIRES, the high-resolution spectrograph for the ELT
Alessandro Marconi, Manuel Abreu, Vardan Adibekyan +99
HIRES will be the high-resolution spectrograph of the European Extremely Large Telescope at optical and near-infrared wavelengths. It consists of three fibre-fed spectrographs prov…
The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity
S. Randich, L. Pasquini, E. Franciosini +20
Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li…
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…
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…
