Abstract

In this study, an eclipsing binary of a short orbital period (P = 1(d).1834857) LV CMa (V = 8(m).7) is selected as a candidate member of an association in the direction of CMa OB1/R1 region. Light curves in UBV RcIc photometric bands were obtained and low-resolution (R similar to 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.
