The pristine nature of SMSS 1605 $-$ 1443 revealed by ESPRESSO

D. S. Aguado, E. Caffau, P. Molaro +20

SMSS J160540.18 $-$ 144323.1 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 0107 $-$ 5240 and other CEMP-no stars with $[Fe/H] \leq - 4.5$

D. Aguado, P. Molaro, E. Caffau +22

HE 0107 $-$ 5240 is a hyper metal-poor star with $[Fe/H] = - 5.39$ . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…

A stellar test of the physics of unification

J. P. P. Vieira, C. J. A. P. Martins, M. J. P. F. G. Monteiro

We discuss the feasibility of using solar-type main-sequence stars as probes of fundamental physics and unification. We use a simple polytropic stellar structure model and study it…
