Velocity and H{alpha} width of 22 Vul
Listed in IVOA Registry (Virtual Observatory)
The 22 Vul system is important for studying the winds and chromospheres of cool evolved stars because the G4 I component is rotating rapidly and probably faster than synchronously.
Description
We discuss the system's physical properties in the context of a wide range of constraints on them and propose values that may be marginally better than previous ones. We use H{alpha} spectroscopy to assess the variability of the cool star's wind, and archival IUE observations to measure variation of density in the wind and rotation of the chromosphere.
