HD 345723: RS Canum Venaticorum Variable Star Detected with TESS Data

CONZO G., MORICONI M. and PERETTO I.

Abstract (from CDS):

This study describes the nature of HD 345723, a variable star identified in TESS photometric data. Analyzing the light curve, we obtain a period of 19 hr and 17 minutes in phase domain. The star, a K6 spectral class, suggest that the variation is due to the presence of large stellar spots in a very close binary system, detected by GAIA spectrum. The double star, at coordinates R.A. (J2000) 20:06:51.33 and decl. (J2000) +22:39:51.7, has a distance of 719 pc, according to reliable GAIA parallax measurements.
