KIC 12602250: A Low-amplitude Double-mode Delta Scuti Star with Amplitude Modulation

We propose for the first time that KIC 12602250 is a low-amplitude radial double-mode $\delta$ Scuti star with amplitude modulation. The detailed frequency analysis given light curve of which delivered from Kepler mission. Fourier long cadence data (i.e. Q0 - Q17, spanning 1471 days) reveals variations are dominated by strongest mode F0 = 11.6141 $\rm{d^{-1}}$, suggesting star. other independent F1 14.9741 $\rm{d^{-1}}$ newly detected. \target $\sim$ 0.06 mag, indicates this star, but ratio F0/F1 estimated as 0.7756 typical HADS, and slow growth detected in $f_{3}$, could be due to stellar evolution, post main sequence crossing instability strip time.
