  bibo_abstract:
  - "The explosion of a white dwarf (WD) in a close binary can launch a surviving
    runaway star at\r\nvelocities of ≳ 1000 km s−1\r\n. Such runaways provide a direct
    probe of thermonuclear supernovae (SNe)\r\nin double-degenerate binaries. Several
    candidate runaways are known, but their evolutionary states\r\nand the demographics
    of the broader population are uncertain. To enable robust population inference,\r\nwe
    carry out a systematic survey for hypervelocity runaways with a simple selection
    function, selecting\r\ncandidates based on large Gaia-inferred tangential velocities
    and blue colors. We classify 100% of the\r\nresulting 92 candidates using a combination
    of spectroscopic follow-up and archival data. The search\r\nyields ten suspected
    D6\r\nstars and three LP 40-365 stars. Three D6\r\nstars are new discoveries,
    including\r\ntwo hot (Teff ≳ 50,000 K) objects and one cool (Teff ≈ 7,000 K) object.
    We forward-model our survey\r\nunder several proposed D6\r\nstar evolutionary
    models, coupling each to a Galactic model and the survey\r\nselection function.
    No single model reproduces the observed diversity of D6\r\nstars, which likely
    reflects\r\na range of remnant masses, ages, and heating mechanisms. Models in
    which runaway companions\r\nare heated by SN shocks alone are too faint and short-lived
    to explain most of the observed sample,\r\nwhile fully reheated models are too
    luminous and long-lived. Models with intermediate heating,\r\nas occurs in some
    simulations of violent mergers and partially disrupted remnants, best match the\r\nobserved
    magnitude, distance, and kinematic-age distributions. The inferred D6\r\nstar
    birth rate is\r\nmodel dependent, but the models that best match the observed
    population require rates of only a\r\nfew percent of the Galactic SN Ia rate,
    perhaps implying that most SNe Ia result from WD binaries\r\nin which both components
    explode. If most SNe Ia do produce surviving runaways, these must be\r\nfainter
    or shorter-lived than the currently known runaways.@eng"
