A potential ϕ Per-type (Be+sdO) binary: FY CMa
2004
Astronomy and Astrophysics
The spectrum of the Be star FY CMa is shown to vary periodically with P = 37.26 ± 0.03 d. The types of variation, exhibiting transient strong shell phases and a radial-velocity variable He emission component, suggest the star to be of the same type as φ Per, i.e. having an evolved hot companion ionizing the outer parts of the primary's circumstellar disc where it faces the hot companion. After φ Per and the candidates 59 Cyg and HR 2142, this is only the fourth promising candidate, although
