  bibo_abstract:
  - Be stars are rapidly rotating main-sequence stars that play a crucial role in
    understanding stellar evolution and binary interactions. In this Letter, we propose
    a new formation scenario for black hole (BH) + Be star binaries (hereafter BHBe
    binaries), where the Be star is produced through the wind Roche lobe overflow
    (WRLOF) mechanism. Our analysis is based on numerical simulations of the WRLOF
    process in massive binaries, building on recent theoretical work. We demonstrate
    that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions
    on stellar wind velocities. Using rapid binary population synthesis, we estimate
    the population of such systems in the Milky Way, predicting ∼1800−3200 currently
    existing BHBe binaries originating from the WRLOF channel. These systems are characterized
    by high eccentricities and exceptionally wide orbits, with typical orbital periods
    exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their
    long orbital separations, these BHBe binaries are promising targets for future
    detection via astrometric and interferometric observations.@eng
