  bibo_abstract:
  - 'Recent observations have found a growing number of hypervelocity stars with speeds
    of ≈1500 − 2500 km s−1 that could have only been produced through thermonuclear
    supernovae in white dwarf binaries. Most of the observed hypervelocity runaways
    in this class display a surprising inflated structure: their current radii are
    roughly an order of magnitude greater than they would have been as white dwarfs
    filling their Roche lobe. While many simulations exist studying the dynamical
    phase leading to supernova detonation in these systems, no detailed calculations
    of the long-term structure of the runaways have yet been performed. We used an
    existing AREPO hydrodynamical simulation of a supernova in a white dwarf binary
    as a starting point for the evolution of these stars with the one-dimensional
    stellar evolution code MESA. We show that the supernova shock is not energetic
    enough to inflate the white dwarf over timescales longer than a few thousand years,
    significantly shorter than the 105 − 6 year lifetimes inferred for observed hypervelocity
    runaways. Although they experience a shock from a supernova less than ≈0.02 R⊙
    away, our models do not experience significant interior heating, and all contract
    back to radii of around 0.01 R⊙ within about 104 years. Explaining the observed
    inflated states requires either an additional source of significant heating or
    some other physics that is not yet accounted for in the subsequent evolution.@eng'
