Further observations of the lambda 10830 He line in stars and their significance as a measure of stellar activity [PDF]
Measurements of the lambda 1030 He line in 198 stars are given along with data on other features in that spectral range. Nearly 80% of all G and K stars show some lambda 10830; of these, half are variable and 1/4 show emission.

Hα Emission among Evolved FGKM Stars: A Compendium from the Literature
Emission in the wings of the H α line among late-type giant stars occurs as a consequence of conditions in their chromospheres. Data from the literature have been used to document the incidence of H α emission among Population I giant stars as a function
