Oxygen isotopic ratio in open cluster RGB stars: A new method for accurate mass and age estimations
O. Straniero, C. Abia, I. Domínguez +1
Determining precise and homogeneous absolute ages of open clusters (OCs) remains a challenge in stellar astrophysics, mainly due to parameter degeneracies in photometric methods an…
The host galaxies of 2003fg-like type Ia supernovae
Lluís Galbany, Chris Ashall, Jing Lu +19
SN~2003fg-like events are a peculiar type Ia supernova (SN~Ia) subtype characterized by broader light curves, higher near-infrared luminosities, and stronger carbon absorptions at…
Tracing the s-Process: Spectroscopic Insights into Chemical Abundances in O- and C-rich Evolved Stars
Sophie Van Eck, Carlos Abia, Inma Dominguez
Oxygen and carbon-rich AGB stars - and objects directly polluted by them - are excellent laboratories to investigate the nucleosynthesis and mixing processes occurring during the l…
The carbon star mystery: forty years later
Oscar Straniero, Carlos Abia, Inmaculata Dominguez
In 1981 Icko Iben Jr published a paper entitled 'The carbon star mystery: why do the low mass ones become such, and where have all the high mass ones gone?', where he discussed the…
Chandrasekhar-mass white dwarfs are the progenitors of a small fraction of Type Ia supernovae according to nucleosythesis constraints
Eduardo Bravo, Luciano Piersanti, Stéphane Blondin +3
The precise progenitor system of type Ia supernovae (SNe Ia), whether it is a white dwarf (WD) close to the Chandrasekhar limit or substantially less massive, has been a matter of…
The RGB tip of galactic globular clusters and the revision of the bound of the axion-electron coupling
O. Straniero, C. Pallanca, E. Dalessandro +5
By combining Hubble Space Telescope (HST) and ground based optical and near-infrared photometric samples, we derive the RGB tip absolute magnitude of 22 galactic globular clusters…
