  - "Context. Rapidly rotating classical OBe stars have been proposed as the products
    of binary interactions, and the fraction of Be stars with compact companions implies
    that at least some are. However, to constrain the interaction physics spinning
    up the OBe stars, a large sample of homogeneously analyzed OBe stars with well-determined
    binary characteristics and orbital parameters are required.\r\n\r\nAims. We investigated
    the multiplicity properties of a sample of 18 Oe, 62 Be, and two Of?p stars observed
    within the BLOeM survey in the Small Magellanic Cloud. We analyzed the first nine
    epochs of spectroscopic observations obtained over approximately three months
    in 2023.\r\n\r\nMethods. Radial velocities (RVs) of all stars were measured using
    cross-correlation based on different sets of absorption and emission lines. Applying
    commonly used binarity criteria, we classified objects as binaries, binary candidates,
    and apparently single (RV stable) objects. We further inspected the spectra for
    double-lined spectroscopic binaries and cross-matched with catalogs of X-ray sources
    and photometric binaries.\r\n\r\nResults. We classify 14 OBe stars as binaries,
    and an additional 11 as binary candidates. The two Of?p stars are apparently single.
    We find two more objects that are most likely currently interacting binaries.
    Without those, the observed binary fraction for the remaining OBe sample of 78
    stars is fobs+candOBe = 0.18 ± 0.04 (fobs+candOBe = 0.32±0.05 including candidates).
    This binary fraction is less than half of that measured for OB stars in BLOeM.
    Combined with the lower fraction of SB2s, this suggests that OBe stars do indeed
    have fundamentally different present-day binary properties than OB stars. We find
    no evidence for OBe binaries with massive compact companions, in contrast to expectations
    from binary population synthesis.\r\n\r\nConclusions. Our results support the
    binary scenario as an important formation channel for OBe stars, as post-interaction
    binaries may have been disrupted or the stripped companions of OBe stars are harder
    to detect. Further observations are required to characterize the detected binaries,
    their orbital parameters, and the nature of their companions.@eng"
