The Blue Straggler Population in Dwarf Galaxies

TL;DR

This paper reviews recent research on Blue Straggler stars in dwarf galaxies, comparing their properties with those in the Galactic Halo and Globular Clusters, highlighting new insights despite limited data.

Contribution

It provides a comparative analysis of Blue Straggler populations in dwarf galaxies, Galactic Halo, and Globular Clusters, emphasizing recent photometric findings.

Findings

Blue Straggler properties in dwarf galaxies are similar to those in the Galactic Halo.

Recent studies have improved understanding of BSS photometric characteristics.

Data limitations are mainly due to the large distances to dwarf galaxies.

Abstract

In this chapter I review the recent developments regarding the study of Blue Stragglers (BSS) in dwarf galaxies. The loose density environment of dwarf galaxies resembles that of the Galactic Halo, hence it is natural to compare their common BSS properties. At the same time, it is unescapable to compare with the BSS properties in Galactic Globular clusters, which constitute the reference point for BSS studies. Admittedly, the literature on BSS in dwarf galaxies is not plentiful. The limitation is mostly due to the large distance to even the closest dwarf galaxies. Nevertheless, recent studies have allowed a deeper insight on the BSS photometric properties that are worth examining.
