AGB and Post-AGB Stars versus Planetary Nebulae and Young Stellar Objects: Properties in Visual and IR Bands

Suh, Kyung-Won

We investigate the properties of AGB and post-AGB (PAGB) stars, planetary nebulae, and young stellar objects (YSOs) in our Galaxy through an analysis of observational data covering visual and infrared (IR) wavelengths. Utilizing datasets from IRAS, 2MASS, AllWISE, Gaia DR3, and the SIMBAD object database, we perform an in-depth comparison between …
