Otero, Sebastian Alberto
Quiescence around V= 2.11-2.21 (AAVSO data). The Be star is likely a blue straggler and therefore probably has an envelope-stripped or degenerate secondary (orbital period 203.5 d.) The 1.2 d. period is likely due to NRP rather than rotational modulation. (2021ApJ...915...13S )
