  • Nebular spectra of pair-ins... Nebular spectra of pair-instability supernovae
    Jerkstrand, A; Smartt, S. J; Heger, A Monthly notices of the Royal Astronomical Society, 01/2016, Volume: 455, Issue: 3
    Journal Article
    Peer reviewed
    Open access

    If very massive stars (M ≳ 100 M⊙) can form and avoid too strong mass-loss during their evolution, they are predicted to explode as pair-instability supernovae (PISNe). One critical test for ...

    Journal Article
    Peer reviewed
    Open access

    ABSTRACT This work examines the relationships between the properties (flux ratios, full width at half-maximum velocities) of the O i λλ6300, 6364, Ca ii λλ7291, 7323, and the Ca ii near-infrared ...

  • The progenitor mass of the ... The progenitor mass of the Type IIP supernova SN 2004et from late-time spectral modeling
    Jerkstrand, A.; Fransson, C.; Maguire, K. ... Astronomy and astrophysics (Berlin), 10/2012, Volume: 546
    Journal Article
    Peer reviewed
    Open access

    SN 2004et is one of the nearest and best-observed Type IIP supernovae, with a progenitor detection as well as good photometric and spectroscopic observational coverage well into the nebular phase. ...

  • LONG-DURATION SUPERLUMINOUS... LONG-DURATION SUPERLUMINOUS SUPERNOVAE AT LATE TIMES
    Jerkstrand, A.; Smartt, S. J.; Inserra, C. ... The Astrophysical journal, 01/2017, Volume: 835, Issue: 1
    Journal Article
    Peer reviewed
    Open access

    ABSTRACT Nebular-phase observations and spectral models of Type Ic superluminous supernovae (SLSNe) are presented. LSQ14an and SN 2015bn both display late-time spectra similar to galaxy-subtracted ...

  • Carbon monoxide formation a... Carbon monoxide formation and cooling in supernovae
    Liljegren, S.; Jerkstrand, A.; Grumer, J. Astronomy and astrophysics (Berlin), 10/2020, Volume: 642
    Journal Article
    Peer reviewed
    Open access

    Context. The inclusion of molecular physics is an important piece that tends to be missing from the puzzle when modeling the spectra of supernovae (SNe). Molecules have both a direct impact on the ...

  • Emission line models for th... Emission line models for the lowest mass core-collapse supernovae – I. Case study of a 9 M⊙ one-dimensional neutrino-driven explosion
    Jerkstrand, A; Ertl, T; Janka, H-T ... Monthly notices of the Royal Astronomical Society, 03/2018, Volume: 475, Issue: 1
    Journal Article
    Peer reviewed
    Open access

    Abstract A large fraction of core-collapse supernovae (CCSNe), 30–50 per cent, are expected to originate from the low-mass end of progenitors with MZAMS = 8–12 M⊙. However, degeneracy effects make ...
