PENA, J. H. et al. A study of the SX Phe star BL Cam. Rev. mex. astron. astrofis [online]. 2021, vol.57, n.2, pp.419-431.  Epub 15-Feb-2022. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2021.57.02.14.

We determined the physical parameters of the SX Phe star BL Cam from newly available times of maximum light and other times from the literature, as well as from uvby − β photoelectric photometry. From our analysis we found that this star is a binary system. The mass of the companion star was calculated in term of the mass of the primary star and the orbital angle. For this star we determined a metallicity [Fe/H] of −1.2 ± 0.3.
