Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars

Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6

The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…

An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi

Yi Yang, Xudong Wen, Lifan Wang +18

The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…

s-process Enriched Post-AGB Star J003643.94-723722.1 in the SMC with an Extreme C/O Ratio and the First Precise Detection of Lead

Meghna Menon, Devika Kamath, Maksym Mohorian +6

Post-asymptotic giant branch (post-AGB) stars are exquisite tracers of s-process nucleosynthesis via their surface abundances. We present a comprehensive analysis of J003643.947…

The true nature of HE0057-5959, the most metal-poor Li-rich star

A. Mucciarelli, P. Bonifacio, L. Monaco +2

The Li-rich stars are a class of rare objects with A(Li) higher than that of other stars in the same evolutionary stage. Their origin is still debated and valuable routes are the C…

Cepheids as distance indicators and stellar tracers

G. Bono, V. F. Braga, A. Pietrinferni

We review the phenomenology of classical Cepheids (CCs), Anomalous Cepheids (ACs) and type II Cepheids (TIICs) in the Milky Way (MW) and in the Magellanic Clouds (MCs). We also exa…

Accurate mass-radius ratios for Hyades white dwarfs

L. Pasquini, A. F. Pala, M. Salaris +4

We use the ESPRESSO spectrograph at the Very Large Telescope to measure velocity shifts and gravitational redshifts of eight bona fide Hyades white dwarfs, with an accuracy better…
