摘要：
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 Halpha emission or significant Li I 6707.81 angstrom 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.
