Investigating the OB associations in CMa using eclipsing binary systems: Preliminary results on LV CMa

Abstract

In this study, an eclipsing binary of a short orbital period (P = 1.^d1834857) LV CMa (V = 8.^m7) is selected as a candidate member of an association in the direction of CMa OB1/R1 region. Light curves in UBVR_cI_c photometric bands were obtained and low-resolution (R ∼ 5500) spectra were collected. Preliminary results show that the system is a detached binary containing at least one B spectral type star. It seems that LV CMa has no connection with the nearby OB associations or stellar clusters.
