  bibo_abstract:
  - Stars stripped of their hydrogen-rich envelopes through binary interaction are
    thought to be responsible for both hydrogen-poor supernovae and the hard ionizing
    radiation observed in low-Z galaxies. A population of these stars was recently
    observed for the first time, but their prevalence remains unknown. In preparation
    for such measurements, we estimate the mass distribution of hot, stripped stars
    using a population synthesis code that interpolates over detailed single and binary
    stellar evolution tracks. We predict that for a constant star formation rate of
    1 M⊙/yr and regardless of metallicity, a scalable model population contains ∼30
    000 stripped stars with mass Mstrip > 1 M⊙ and ∼4000 stripped stars that are sufficiently
    massive to explode (Mstrip > 2.6 M⊙). Below Mstrip = 5 M⊙, the distribution is
    metallicity-independent and can be described by a power law with the exponent
    α ∼ −2. At higher masses and lower metallicity (Z ≲ 0.002), the mass distribution
    exhibits a drop. This originates from the prediction, frequently seen in evolutionary
    models, that massive low-metallicity stars do not expand substantially until central
    helium burning or later and therefore cannot form long-lived stripped stars. With
    weaker line-driven winds at low metallicity, this suggests that neither binary
    interaction nor wind mass loss can efficiently strip massive stars at low metallicity.
    As a result, a “helium-star desert” emerges around Mstrip = 15 M⊙ at Z = 0.002,
    covering an increasingly large mass range with decreasing metallicity. We note
    that these high-mass stars are those that potentially boost a galaxy’s He+-ionizing
    radiation and that participate in the formation of merging black holes. This “helium-star
    desert” therefore merits further study.@eng
