cds-question@unistra.frvariable-starsspectroscopyThe aim of this work was to use a multi-approach technique to derive the most accurate values possible of the physical parameters of the delta Sct star HD 174966, which was observed with the CoRoT satellite. In addition, we searched for a periodic pattern in the frequency spectra with the goal of using it to determine the mean density of the star. First, we extracted the frequency content from the CoRoT light curve. Then, we derived the physical parameters of HD 174966 and carried a mode identification out from the spectroscopic and photometric observations. We used this information to look for the models fulfilling all the conditions and discussed the inaccuracies of the method because of the rotation effects. In a final step, we searched for patterns in the frequency set using a Fourier transform, discussed its origin, and studied the possibility of using the periodicity to obtain information about the physical parameters of the star.2013A&A...559A..63Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/559/A63CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/506/79 : HD 174936 asteroseismic analysis (Garcia Hernandez+, 2009)J/A+A/506/85 : HD 50844 observed by CoRoT (Poretti+, 2009)J/A+A/506/143 : Pulsations of HD 181231 (Neiner+, 2009)J/A+A/525/A23 : Frequency analysis of HD 49434 (Mathias+, 2011)J/MNRAS/415/1577 : CoRoT 105288363 Blazhko modulation (Guggenberger+, 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/559/A63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/559/A63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/559/A63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/559/A63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/559/A63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/559/A63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/559/A63/freqsHD 174966 photometric frequencies from CoRoTID[1/185] Frequency ID numbermeta.id;meta.mainintprimaryFreq1[0.049/77.12] Frequency in cycles per dayd**-1em.freqdoublee_Freq1Error in the determination of the frequencyd**-1stat.errordoubleFreq2Frequency in {mu}HertzuHzem.freqdoubleAmp[0.007/6.3] Amplitude of the frequencymmagphot.magfloate_AmpError in the determination of the amplitudemmagstat.errorfloatPhase[-3.14/3.141] Phase of the frequencyradem.freqdoublee_PhaseError in the determination of the phaseradstat.error;time.phasedoubleSig[10/11621] Spectral significance of the frequencystat.fit.goodnessdoubleS/N[3.6/3385] Signal-to-noise ratio of the frequencystat.snr;em.freqdoublermsRoot mean square before extracting the frequencymmagstat.errorfloatComClose frequencies and possible combinationsmeta.notechar
