Asteroseismic analysis of the CoRoT δ Scuti star HD 174936 García Hernández, Antonio Moya, Andrés Garrido, R. Suárez Yanes, Juan Carlos Rodríguez, E. Amado, P. J. Martín Ruiz, Sergio Rolland Quintanilla, Ángel We present an analysis of the δ-Scuti star HD 174936 (ID 7613) observed by CoRoT during the first short run SRc01 (27 days). A total number of 422 frequencies were extracted from the light curve using standard prewhitening techniques. This number of frequencies was obtained by considering a spectral significance limit of sig = 10 using the software package SigSpec. Our analysis of the oscillation frequency spectrum reveals a spacing periodicity around 52 μHz. Although modes considered here are not in the asymptotic regime, a comparison with stellar models confirms that this signature may stem from a quasi-periodic pattern similar to the so-called large separation in solar-like stars. 2024-02-12T12:18:26Z 2024-02-12T12:18:26Z 2009 journal article https://hdl.handle.net/10481/89083 10.1051/0004-6361/200911932 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional EDP Sciences
