Stellar population astrophysics (SPA) with the TNG. Revisiting the metallicity of Praesepe (M44)
Valentina D'Orazi, Ernesto Oliva, Angela Bragaglia +8
Open clusters exquisitely track the Galactic disc chemical properties and its time evolution; a substantial number of studies and large spectroscopic surveys focus mostly on the ch…
The GALAH Survey: Temporal Chemical Enrichment of the Galactic Disk
Jane Lin, Martin Asplund, Yuan-Sen Ting +22
We present isochrone ages and initial bulk metallicities (, by accounting for diffusion) of 163,722 stars from the GALAH Data Release 2, mainly composed of main…
What is a globular cluster? An observational perspective
Raffaele Gratton, Angela Bragaglia, Eugenio Carretta +3
Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters of stars, they exhibit signs of some chemical evolution. At least for this reason, the…
VLT/SPHERE exploration of the young multiplanetary system PDS70
D. Mesa, M. Keppler, F. Cantalloube +51
Context. PDS 70 is a young (5.4 Myr), nearby (~113 pc) star hosting a known transition disk with a large gap. Recent observations with SPHERE and NACO in the near-infrared (NIR) al…
Investigating the nature of the extended structure around the Herbig star RCrA using integral field and high-resolution spectroscopy
E. Rigliaco, R. Gratton, D. Mesa +24
We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
Stellar population astrophysics (SPA) with the TNG. Characterization of the young open cluster ASCC 123
A. Frasca, J. Alonso-Santiago, G. Catanzaro +10
Star clusters are key to understand the stellar and Galactic evolution. ASCC 123 is a little-studied, nearby and very sparse open cluster. We performed the first high-resolution sp…
