| CHR 145 | The primary is DH Leo, a RS CVn system, and spectroscopic binary with | |
| a period of 1.07d (Barden, AJ 89, 683, 1984). Barden observed three K | ||
| stars in his spectra of this system. Fekel (1989, private comm.) has | ||
| observed the third component of this system and finds no velocity | ||
| changes in excess of +/- 2 km/sec from 12 spectra obtained since 1984. | ||
| This new speckle component is thought to be this third spectroscopic | ||
| component. | McA1990 |
