A spectroscopic and photometric study of the giant star HD 101841: a very short-period binary system.

DE MEDEIROS J.R., DUQUENNOY A., LEBRE A. and BURKI G.

Abstract (from CDS):

The giant star HD 101841 is a single lined spectroscopic binary with an orbital period of 3.11 days and an assumed circular orbit. No sign of Hα emission or significant Li I 6707.81 A features were found. Photometric observations show a micro-variability of about 0.014 magnitude in V. Different studies give a F3II spectral classification but we found strong evidences that HD 101841 is probably a F3III-IV giant star.
