| Abstract: |
A spectroscopic and photometric study is presented for HD 112989, an unusually active giant star. The present spectroscopic observations show a Ca 2 H and K emission core variability, whereas the UBV photometry shows that HD 112989 has a variable brightness. The rotational velocity for this star, 11.0 km s^{-1}, is about five times larger than the mean rotational velocity for giants with the same spectral type. In addition, we have found no sign of binarity for this star. |
