| dc.description | The binary nature of the bright (V = 4.2 mag) Mercury-Manganese star Phi Her has been known since 1976 and it was considered a low-amplitude single-lined SB. In a recent study we found evidence for lines of the secondary star. Other recent results from interferometry provide a good measure of the light ratio. It is very plausible that the secondary is a late main-sequence A star. We find the rotational velocity of the secondary to be ~42 +/- 5 km/s. | |
