Surface rotation of Kepler red giant stars

Kepler allows the measurement of starspot variability in a large sample of field red giants for the first time. With a new method that combines autocorrelation and wavelet...开普勒太空望远镜（Kepler）首次实现了对大样本野场红巨星星斑变异性的测量。依托一种结合自相关（autocorrelation）与小波（wavelet）分析的全新方法……
