HO Puppis: Not a Be Star, but a Newly Confirmed IW And-type Star

Abstract: HO Puppis (HO Pup) was considered as a Be-star candidate based on its γ Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia Data Release 2 and the spectral-energydistribution fit on broadband photometry, the Be-star nature of HO Pup is ruled out. Furthermore, based on the 28,700 photometric data points collected from various time-domain surveys and dedicated intensive-monitoring observations, the light curves of HO Pup closely resemble those of IW And-type sta… Show more

“…estimated based on bootstrap resampling method. We then checked the LS periods using a multiband phase-dispersion minimization (PDM) periodogram developed in Lee et al (2021). If both periods agree (e.g., the periods are within 10% of each others) we adopted the LS periods, else we visually inspected the phased light curves and selected the period that resulted a smoother light curve.…”
