Light curve of HD 172189
Listed in IVOA Registry (Virtual Observatory)
The eclipsing delta-Scuti star HD 172189 is a probable member of the open cluster IC 4756 and a promising candidate target for the CoRoT mission.
Description
The detection of pulsation modes is the first step in the asteroseismological study of the star. Further, the calculation of the orbital parameters of the binary system allows us to make a dynamical determination of the mass of the star, which works as an important constraint to test and calibrate the asteroseismological models.
We performed a detailed frequency analysis of 210 hours of photometric data of HD 172189 obtained from the STEPHI XIII campaign. We have identified six pulsation frequencies with a 99% confidence level and a seventh with a 65% confidence level, in the range between 100-300uHz. In addition, three eclipses were observed during the campaign, allowing us to improve the determination of the orbital period of the system.
