The solar photospheric silicon abundance according to CO5BOLD: Investigating line broadening, magnetic fields, and model effects
S. A. Deshmukh, H. -G. Ludwig, A. Kučinskas +5
In this work, we present a photospheric solar silicon abundance derived using CO5BOLD model atmospheres and the LINFOR3D spectral synthesis code. Previous works have differed in th…

G. Cescutti, P. Bonifacio, E. Caffau +20
In recent years, Galactic archaeology has become a particularly vibrant field of astronomy, with its main focus set on the oldest stars of our Galaxy. In most cases, these stars ha…
Chemically Peculiar Stars in the Open Cluster Stock 2
Laia Casamiquela, Marwan Gebran, Marcel Agüeros +2
The recently re-discovered open cluster Stock 2, located roughly 375 pc away and about 400 Myr old, has the potential to be an exciting new testbed for our understanding of stellar…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
The Gaia-ESO Survey: Lithium measurements and new curves of growth
E. Franciosini, S. Randich, P. de Laverny +37
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that was carried out using the multi-object FLAMES spectrograph at the Very Large Telescope. The survey provides ac…
7Be detection in the 2021 outburst of RS Oph
P. Molaro, L. Izzo, P. Selvelli +7
The recurrent nova RS Oph underwent a new outburst on August 8, 2021, reaching a visible brightness of V = 4.8 mag. Observations of the 2021 outburst made with the high resolution…
