Period Variation of the Close Eclipsing Binary V405 Draconis.

PYATNYTSKYY M.Y. and ANDRONOV I.L.

Abstract (from CDS):

We found a period variation of the close binary of EW type V405 Draconis. From the O - C diagram built using survey data, data from the literature, and our observations, we calculated a period increase rate (1/P)(dP/dt) of 2.72(0.03) · 10–6 yr–1. Along with the monotonic period increase, TESS data demonstrates a sign of a cyclic variation of the period. We estimated the period of such cyclic variations as 537.9(1.4) days with a semi-amplitude of 0.00200(0.00001) days. This can provide evidence for the presence of the third body in the system.
