Astrophysics and Space Science Aims and scope Submit manuscript

Abstract

New photoelectric photometry of TW Cam is presented. Fourier analysis of the light curve shows a group of peaks at 43d. The first return maps of the primary and secondary minima differ remarkably, that of the secondary minima showing significantly larger scatter. This difference implies that the pulsation period of the star is the formal period (i.e., the distance between two primary minima).
