Abstract: | The eclipsing binary NN Vir is a short period system showing an EW-type light curve. Photometric observations of NN Vir were
done by Gomez–Ferrellad and Garcia–Melendo (1997) at Esteve Duran Observatory. The first spectroscopic observations of this
system were obtained by Rucinski and Lu (1999). The radial velocity and light curves analysis was made with the latest version
of the Wilson program (1998), and the geometric and physical elements of the system are derived. From the simultaneous solutions
of the system, we determined the masses and radii of the components: 1.89 M
⊙ and 1.65 R
⊙ for the primary component; 0.93 M
⊙ and 1.23 R
⊙ for the secondary component. We estimated effective temperatures of 7030 K for the primary and 6977 K for the secondary component. |
