Infrared Spectra of Late-Type Stars [PDF]

, 1971
Spectra have been obtained in the 2μ atmospheric window with a resolution of 32 and 65Å of late-type dwarfs, giants, supergiants, and long period variables. In the non-variable stars, the first overtone band of C0 at 2.29μ shows a systematic increase with both increasing luminosity and decreasing temperature. This increasing strength is interpreted as

Absolute magnitudes of late-type stars

Astrophysics and Space Science, 1986
The improved calibration of absolute magnitude versus spectral type and luminosity class is presented for carbon stars and for K- to M-type giants. It is based on the recent results estimated by applying the maximum-likelihood method and other statistical methods to the homogeneous kinematical data including the proper motions in the AGK3 system.

Theoretical Visibility Curves of Late Type Stars

Astrophysics and Space Science, 1995
Theoretical visibility curves are presented for one carbon and one oxygen star. We aim to show the importance of measurements at wavelengths across the band.

Winds of Late Type Stars

1990
Cool stars on the asymptotic giant branch (AGB) form a late stage of stellar evolution shortly before loosing their outer layers and moving into the state where a planetary nebula is excited. These stars show severe mass-loss rates between 10−8 M ⊙yr−1 at the lower AGB, increasing to some l0−4 M ⊙yr−1 as the star evolves to the top of the AGB while ...

Spectroscopic study of late type stars

Vistas in Astronomy, 1966
Abstract Spectroscopic investigation of late type stars from both observation and theory is discussed. Starting from the identification problem of elements in these stars, some preliminary studies of chemical abundance are made by the curve of growth method.
