    • 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 ...
    • 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
      Open Access
      Abridged: 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
      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 ...
    • Production of short-lived radioactive nuclei in super asymptotic giant branch star 

      Doherty, Carolyn L.; Lugaro, M.; Lau, H.; Siess, Lionel; Lattanzio, John; Gil Pons, Pilar (2012-08-08)
      Article
      Open Access
    • Production of short-lived radioactive nuclei in Super Asymptotic Giant Branch stars 

      Doherty, Carolyn L.; Lugaro, M.; Lau, H. H. B.; Siess, Lionel; Lattanzio, John; Gil Pons, Pilar (2012)
      Conference report

    • 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 asymptotic giant branch stars. I - Evolution code comparison 

      Doherty, Carolyn L.; Siess, Lionel; Lattanzio, John; Gil Pons, Pilar (2010-01-01)
      Article
      Restricted access - publisher's policy
      We present an extensive set of detailed stellar models in the mass range 7.7–10.5M over the metallicity range Z = 10−5–0.02. These models were produced using the Monash University version of the Mount Stromlo Stellar ...
    • 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 ...
    • 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 ...
