Giant Eruptions and Pre-Supernova Evolution (SN impostors, LBVs, hypergiants and "red" transients)
Organizers -- Davidson, Humphreys, Langer
Morning Invited Plenary Review Talks -- (9:00 a.m. - 12:30 p.m. with break)
  • LBVs- Their Variability and Formation of Nebulae -- Kerstin Weis
  • Giant Eruptions(Impostors) -- Schuyler Van Dyk
  • Origin of the Instability: Surface -- Jorick Vink
  • Origin of the Instability:Interior -- David Arnett
Topics for the afternoon discussion -- (2:00 - 5:30 p.m. with break)

1. What is the Progenitor Class of Evolved Stars -- of LBVs, of Giant Eruptions as a Function of Mass, Relations to RSGs, AGBs?
    • Nolan Walborn -- LBVs
    • Armin Rest -- eta Car
    • Mansi Kasliwal -- Red Transients
      • Do high mass loss episodes occur in Pop III?
        • Dominik Bomans -- Transients at Low Metallicity
      2. Recovery from a Giant Eruption -- The Survivors
        • Kris Davidson -- eta Car from 1890 - Present
        • Chris Kochanek -- Dust in Massive Transients
        How does a giant eruption affect future evolution?

      3. Surface vs. Interior Instabilities (in different mass ranges)
        Surface -- the Eddington limit in its various forms (opacity, rotation, the bi-stability jump) and the LBV/S Dor instability strip
        • Joyce Guzik -- Origin of LBV Instability
        • Noam Soker -- Accretion Onto a Companion
        Can giant eruptions be explained by surface instabilities?

        Interior -- What kind of instabilities occur, can they explain giant eruptions?

        • Josh Shiode--Wave-Driven Mass Loss, a Mechanism for Late-stage Stellar Eruptions

        What physics is or still needs to be included in the codes?
      Poster viewing -- (5:30 - 6:30pm) and Happy Hour

    Supernovae and Hypernovae -- their progenitors and progeny (Types II's, Ib and Ic, Type IIn's, super luminous SN, and the origin of GRBs)
    Organizers -- Heger, Smartt, Woosley, Arnett
    Morning Invited Plenary Review talks -- (9:00am - 12:00pm)

      • Jill Gerke -- A Search for Failed SNe

      3. What is the role of the pulsational pair instability?

      • Ken Chen -- Supernovae from the Most Massive Stars

      4. What is the role of pre-terminal interior instabilities?

      • Jeremiah Murphy -- Explosion Conditions and the Effects of Multi-dimensional Instabilities

      Are these related to the non-terminal giant eruptions (see Day 1)?

      What physics is or still needs to be included in the codes?

      • Ugalde -- 12C research
    Conference Dinner on the University of Minnesota Showboat (6:30 -9:30 p.m.) with a surprise after dinner speaker on "world domination."
