Populations of AGB stars and LPVs in the Galaxy and Local Group

TL;DR

This review summarizes recent advances in understanding AGB stars and LPVs across the Galaxy and Local Group, highlighting results from infrared surveys, microlensing, and narrow-band imaging that reveal their properties and distributions.

Contribution

It compiles recent observational findings on AGB stars and LPVs, emphasizing the role of infrared and survey data in characterizing these populations.

Findings

Infrared surveys have improved AGB star detection and classification.

Microlensing surveys have provided insights into the distribution of LPVs.

Narrow-band imaging has enhanced understanding of chemical properties of AGB stars.

Abstract

In this review I will discuss recent developments on the topic of resolved Asymptotic Giant Branch (AGB) stars and Long Period Variables (LPVs) in our Galaxy, the Magellanic Clouds, and the Local Group in general. Since the main characteristics of AGB stars are (1) their infrared, (2) pulsational and (3) chemical properties, it is fitting that I will focus on recent results from the (a) 2MASS/DENIS and MSX near- and mid-IR surveys, the (b) micro-lensing surveys and (c) dedicated narrow-band imaging surveys.
