# Radial Distribution of Blue Stragglers in NGC 5466 using AstroSat

## TL;DR

This study uses UV imaging from AstroSat to analyze the distribution of Blue Straggler Stars in NGC 5466, revealing their central concentration and emphasizing the importance of UV data and membership info.

## Contribution

First UV-based analysis of BSS radial distribution in NGC 5466, demonstrating the significance of UV imaging and membership data in such studies.

## Key findings

- BSSs are more centrally concentrated than HB stars.
- No significant rise in BSS distribution in outer regions.
- Membership info is crucial for accurate BSS distribution analysis.

## Abstract

We present the results obtained from Near-UV observations of the cluster NGC 5466 taken with UVIT onboard AstroSat to study the radial distribution of Blue Straggler Stars (BSSs), covering the cluster region up to a radius of 14$'$. Our study confirms that the BSSs are more centrally concentrated than Horizontal Branch (HB) stars in the cluster. We do not find a statistically significant rising trend in the radial distribution of BSSs for the outer regions, as most of the previously catalogued BSSs that are located in the cluster outskirts were found to be non-members, quasars or galaxies. This study highlights the importance of UV imaging combined with membership information to probe the radial distribution of BSSs.
