Maintenance of the Pulsation in Cepheid Variables

Nature volume 140, page 195 (1937)Cite this article

Abstract

THE oscillations induced in the principal modes of vibration of a star by a free oscillation in one of them, generally of the second order in the corresponding free amplitude, are unimportant unless magnified by resonance ; so seems the evidence from Miss H. A. Kluyver's analysis1. Hence, the motion in a Cepheid variable may be closely approximated to by the superposition of the oscillations of two modes of vibration, a free one and a forced one with half the period.
