  • Evolution and CNO yields of Z = 10-5 stars and possible effects on carbon-enhanced metal-poor production 

    Gil Pons, Pilar; Doherty, Carolyn L.; Lau, Herbert B.; Campbell, Simon W; Suda, Takuma; Guilani, Shervin Mansouri; Gutiérrez Cabello, Jordi; Lattanzio, John C. (2013-09)
    Article
    Open Access
    Aims. 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 ...
  • 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)
    Conference lecture
    Open Access
    Super 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 

    Doherty, Carolyn L.; Lattanzio, John C.; Angelou, George; Campbell, Simon W; Church, Ross; Constantino, Thomas; Cristallo, Sergio; Gil Pons, Pilar; Karakas, Amanda; Lugaro, Maria; Stancliffe, Richard (Cambridge University Press, 2016)
    Conference lecture
    Open Access
    The 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 ...
  • 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
    Open Access
    Getting 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 ...
  • Super-AGB stars and their role as electron capture supernova progenitors 

    Doherty, Carolyn L.; Gil Pons, Pilar; Siess, Lionel; Lattanzio, John C. (2017-11-23)
    Article
    Open Access
    We review the lives, deaths and nucleosynthetic signatures of intermediate-mass stars in the range ˜6–12 M¿, which form super-AGB stars near the end of their lives. The critical mass boundaries both between different types ...
  • Super and massive AGB stars - III. nucleosynthesis in metal-poor and very metal-poor stars - Z = 0.001 and 0.0001 

    Doherty, Carolyn L.; Gil Pons, Pilar; Lau, Herbert B.; Lattanzio, John C.; Siess, Lionel; Campbell, Simon W (2014-05)
    Article
    Open Access
    We present a new grid of stellar models and nucleosynthetic yields for super-AGB stars with metallicities Z = 0.001 and 0.0001, applicable for use within galactic chemical evolution models. Contrary to more metal-rich stars ...
  • Super- and massive AGB stars - IV. Final fates initial-to-final mass relation 

    Doherty, Carolyn L.; Gil Pons, Pilar; Siess, Lionel; Lattanzio, John C.; Lau, Herbert B. (2015-01-21)
    Article
    Open Access
    We explore the final fates of massive intermediate-mass stars by computing detailed stellar models from the zero-age main sequence until near the end of the thermally pulsing phase. These super-asymptotic giant branch ...
