Equivalent Width of Hα in Late-Type Stars
- Creators
- Weistrop, Donna
Abstract
The use of the equivalent width of Ha as a luminosity criterion for late-type stars is investigated. The method is found to be no more accurate than MK luminosity classifications. Two spectrograms are presented which indicate a change in the Ha equivalent width in 22 Vul over a three-year period.
