| Abstract: |
The preliminary results of an analysis of the KIC 5390438 and KIC 5701829 light curves
are presented. The variations of these stars were detected by Baran et al. (2011a) in a
search for pulsating M dwarfs in the Kepler public database.
The objects have been observed by the Kepler spacecraft during the
Q2 and Q3 runs in a short-candence mode (integration time of ∼1 min). A Fourier analysis of the time series
data has been
performed by using the PERIOD04 package. The resulting power spectrum of each star shows a
clear excess of power in the frequency
range 100 and 350μHz with a sequence of spaced peaks typical of solar-like oscillations.
A rough estimation of the large and small separations has been obtained.
Spectroscopic observations
secured at the Observatorio Astronomico Nacional in San Pedro Mártir allowed us to derive a
spectral classification
K2III and K0III for KIC 5390438 and KIC 5701829, respectively.
Thus, KIC 5390438 and KIC 5701829 have been identified as solar-like oscillating red giant stars. |
