cds-question@unistra.freclipsing-binary-starssolar-system-planetsspectroscopyEclipsing 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.2014A&A...565A..55Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/565/A55CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/598/597 : Frequency analysis of fundamental-mode RR Lyrae (Alcock+, 2003)J/A+A/506/111 : Frequency analysis of HD 180642 (V1449 Aql) (Degroote+, 2009)J/A+A/506/471 : Frequency analysis of CoRoT B stars (Degroote+, 2009)J/A+A/525/A23 : Frequency analysis of HD 49434 (Mathias+, 2011)J/A+A/551/A12 : HD 48977 frequency analysis (Thoul+, 2013)J/A+A/556/A87 : CoRoT-100866999 frequency analysis (Chapellier+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/565/A55https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/565/A55http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/565/A55https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/565/A55https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/565/A55http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/565/A55GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/565/A55/table3CoRoT 105906206 frequencies, amplitudes and phases after subtracting the binary model (P=3.6945708)recnoRecord number assigned by the VizieR team.
