Abstract:
The orbit and physical parameters of the previously unsolved
double-lined eclipsing binary V570 Per are derived using Asiago
Echelle high-resolution and high S/N spectroscopy, and B, V
photo-electric photometry. Effective temperatures, gravities,
rotational velocities, and metallicities of both components are also
obtained from atmospheric chi2 analysis. The observed properties of
V570 Per components are compared to available families of stellar
evolutionary tracks, in particular to BaSTI models computed on purpose
for exactly the observed masses and varied chemical compositions.
Description:
The data presented in this catalogue are the results of the
photometric observations of V570 Per obtained with a 28cm
Schmidt-Cassegrain telescope equipped with an Opted SSP5 photoelectric
photometer. In all, the measurements for V570 Per consist of 446
measurements in B and 465 in V standard Johnson bands, secured between
2000 and 2003 and covering the whole lightcurve of V570 Per eclipsing
binary star. The dispersion of B and V points around the derived
orbital solution for V570 Per (see Fig. 1 of the paper) is 0.007 and
0.006, respectively.
