The satellite CoRoT ( Convection , Rotation , and planetary Transits ) has provided high-quality data for almost six years .
We show here the asteroseismic analysis and modeling of HD169392A , which belongs to a binary system weakly gravitationally bound as the distance between the two components is of \sim 4250 AU .
The main component , HD169392A , is a G0IV star with a magnitude of 7.50 while the second component is a G0V-G2IV star with a magnitude of 8.98 .
This analysis focuses on the main component , as the secondary one is too faint to measure any seismic parameters .
A complete modeling has been possible thanks to the complementary spectroscopic observations from HARPS , providing T _ { eff } =5985 \pm 60K , \log g =3.96 \pm 0.07 , and [ Fe/H ] =-0.04 \pm 0.10 .
