Article
Accés obertAims. Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these stars. Methods. Using ... -
Explosion of white dwarfs harboring hybrid CONe cores
Bravo Guil, Eduardo; Gil Pons, Pilar; Gutiérrez Cabello, Jordi; Doherty, Carolyn L. (EDP Sciences, 2016-04-12)
Article
Accés obertRecently, it has been found that off-center carbon burning in a subset of intermediate-mass stars does not propagate all the way to the center, resulting in a class of hybrid CONe cores. The implications of a significant ... -
Hiding in plain sight - red supergiant imposters? Super-AGB stars
Doherty, Carolyn L.; Gil Pons, Pilar; Lattanzio, John C.; Siess, Lionel (Cambridge University Press, 2015)
Comunicació de congrés
Accés obertSuper Asymptotic Giant Branch (Super-AGB) stars reside in the mass range ˜ 6.5-10 M¿ and bridge the divide between low/intermediate-mass and massive stars. They are characterised by off-centre carbon ignition prior to a ... -
Monash Chemical Yields Project (Mon¿ey) - Element production in low- and intermediate-mass stars of metallicities Z = 0 to 0.04

Accés obertThe Mon¿ey project will provide a large and homogeneous set of stellar yields for the low- and intermediate- mass stars and has applications particularly to galactic chemical evolution modelling. We describe our detailed ... -
Nucleosynthetic yields of Z=1e-5 intermediate-mass stars
Gil Pons, Pilar; Doherty, Carolyn L.; Gutiérrez Cabello, Jordi; Campbell, Simon W; Siess, Lionel; Lattanzio, John C. (EDP Sciences, 2020-10-23)
Article
Accés obertAbridged: Observed abundances of extremely metal-poor (EMP) stars in the Halo hold clues for the understanding of the ancient universe. Interpreting these clues requires theoretical stellar models at the low-Z regime. We ... -
Primordial to extremely metal-poor AGB and Super-AGB stars: White dwarf or supernova progenitors?
Gil Pons, Pilar; Doherty, Carolyn L.; Gutiérrez Cabello, Jordi; Siess, Lionel; Wattana Campbell, Simon; Lau, Herbert B.; Lattanzio, John C. (2018-11-29)
Article
Accés obertGetting a better understanding of the evolution and nucleosynthetic yields of the most metal-poor stars ( Z ¿ 10 ¿5 ) is critical because they are part of the big picture of the history of the primitive universe. Yet many ... -
