报告摘要:
A seismic analysis of the star KIC 6951642 observed with the Kepler satellite is reported. The star was observed in long cadence mode (exposure time 30 min) during 16 quarters between 2009 and 2013 years. The oscillation spectrum of KIC 6951642 is characterized by the presence of low and high frequency peaks typical of those present in Delta Scuti and Gamma Doradus stars. Therefore, this target is likely a hybrid star showing both kind of oscillations - Delta Sct and Gamma Dor. The Fourier analysis of the light curve yielded detection of 30 oscillation frequencies with a confidence level above 99%.In this talk I will present? an introduction?to asteroseismology, the use of KEPLER data and some preliminary results on the analysis of KIC6951642.
