Abstract:
Eclipsing binary systems with pulsating components allow determination
of several physical parameters of the stars, such as mass and radius,
that can be used to constrain the modeling of stellar interiors and
evolution when combined with the pulsation properties. We present the
results of the study of CoRoT 105906206, an eclipsing binary system
with a pulsating component located in the CoRoT LRc02 field.
The analysis of the CoRoT light curve was complemented by
high-resolution spectra from the Sandiford at McDonald Observatory and
FEROS at ESO spectrographs, which revealed a double-lined
spectroscopic binary. We used an iterative procedure to separate the
pulsation-induced photometric variations from the eclipse signals.
First, a Fourier analysis was used to identify the significant
frequencies and amplitudes due to pulsations. Second, after removing
the contribution of the pulsations from the light curve we applied the
PIKAIA genetic-algorithm approach to derive the best parameters for
describing the system orbital properties.
Description:
The file frequenc.dat contains the table with 220 frequencies,
amplitudes, and phases, together with their uncertainties, derived for
the light curve of CoRoT 105906206 with pulsations only (after
subtracting the best binary model). The uncertainties are the formal
values computed using equations (4), (10), and (11) of Montgomery &
O'Donoghue (1999DSSN...13...28M 1999DSSN...13...28M).
