Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
On the 12C/13C isotopic ratio at the dawn of chemical evolution
P. Molaro, D. S. Aguado, E. Caffau +21
The known Mega and Hyper Metal-Poor (MMP-HMP) stars with [Fe/H]<-6.0 and <-5.0, respectively, likely belong to the CEMP-no class, i.e. carbon-enhanced stars with low or absent seco…
The pristine nature of SMSS 16051443 revealed by ESPRESSO
D. S. Aguado, E. Caffau, P. Molaro +20
SMSS J160540.18144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H]=-6.2, which was first reported with the SkyMapper tele…
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…
Accretion and Outflows in Young Stars with CUBES
J. M. Alcalá, G. Cupani, C. J. Evans +2
The science case on studies of accretion and outflows in low-mass (1.5 ) young stellar objects (YSOs) with the new CUBES instrument is presented. We show the need for…
Chemical Composition of a Palomar 12 Blue Straggler
L. Pasquini, P. Bonifacio, L. Pulone +5
With the equivalent area of a 16m telescope, ESPRESSO in 4UT mode allows to inaugurate high resolution spectroscopy for solar-type stars belonging to extragalactic globular cluster…
