Abstract

PENA, J. H. et al. A study of BO Lyn, a neglected hads star. Rev. mex. astron. astrofis [online]. 2016, vol.52, n.2, pp.385-398. ISSN 0185-1101.

uvby − β photometry of the high amplitude δ Scuti (HADS) star BO Lyn allowed us to determine its physical characteristics. A secular period variation was established through the O-C of all the available times of maximum light and those newly acquired through CCD photometry. In the present study we have demonstrated that BO Lyn is pulsating with one stable varying period whose O-C residuals show a sinusoidal pattern compatible with a light-travel time effect.

Keywords : stars: variables: delta Scuti; techniques: photometric.
