Optical system.
From James Kaler's Star Notes:
Vindemiatrix is a somewhat unusual star, a middling temperature (4,990 Kelvin)
yellow class G giant only a bit cooler than the Sun. As a giant, however, it is considerably
brighter than the Sun. It has a radius 12 times that of the Sun, similar to the brighter,
-6-
Zone 167
cooler component of Capella. The star seems to be a about 15% richer than the Sun in
metals, and is somewhat distinguished by having most of its motion in the direction
perpendicular to the line of sight, making it appear to move rather rapidly against the
background stars, a second of arc in five years.
Much more significantly, Vindemiatrix is a rather powerful X-ray source, implying
considerable magnetic surface activity. Its total X-ray radiation is almost 300 times that
of the Sun, ranking it third among nearby cool single giants and beat out only by Deneb
Kaitos and a star called 24 Ursae Majoris, which lies northeast of the bowl of the Big
Dipper. (The double star Capella far exceeds it, the X-radiating component unknown.)
Though Vindemiatrix has surely ceased fusing hydrogen to helium in its core, its exact
internal structure is uncertain. At three solar masses, it probably began life as a bluewhite class B star, and is now either in transition to beginning to fire up its internal
helium or has already begun to do so.
Observations:
C8 at 104x. Use averted vision and tap the tube to glimpse B.
