Dusty Stellar Source Classification by Implementing Machine Learning Methods Based on Spectroscopic Observations in the Magellanic Clouds

The Astrophysical Journal
Dusty stellar point sources are a significant stage in stellar evolution and contribute to the metal enrichment of galaxies. These objects can be classified using photometric and spectroscopic observations using color–magnitude diagrams and infrared ...

Asymptotic giant branch stars near the sun

The Astronomical Journal, 1992
The available red and near infrared photometry of M, S, and C stars in the Bright Star Catalogue is discussed on the basis of the asymptotic giant branch (AGB) ledge in the temperature-luminosity plane that was previously found to satisfy all old disk population objects.

Observations of Molecular CN toward S-type Asymptotic Giant Branch Stars

The Astronomical Journal
S-type asymptotic giant branch (AGB) stars are defined by their carbon-to-oxygen (C/O) ratio approaching unity. However, observations of circumstellar molecules in these stars are limited and challenging.
