alp Her = Rasalgethi. Star A is an irregular variable, and B is an |
|
|
SB1, P = 51.58 d. Spectrum composite; G5III+F2V. Radial velocity |
|
|
measures by Smith (1988 private comm.) for alp Her A since 1984 |
|
|
have shown an increase in velocity by about 11 km/sec during a |
|
|
three-year interval, then an apparent turnover in velocity during |
|
|
the fourth year. This suggests a component with a period of the |
|
|
order of a decade; it now appears that this system may have at least |
|
|
5 physical components. Measure of 1927.43 made by triangulation of |
|
|
multiple measures. |
|
|
The 1779.66 measure by Herschel was corrected. |
