# Using Gaia DR2 to detect extratidal structures around the Galactic globular cluster NGC362

## TL;DR

This paper demonstrates how Gaia DR2 data can be used to identify extratidal structures around the globular cluster NGC362, revealing a distinct stellar component separate from nearby populations.

## Contribution

It introduces a modified statistical decontamination method to detect extratidal features using Gaia DR2 data around NGC362.

## Key findings

- Identification of a significant stellar component associated with NGC362
- Successful distinction of NGC362 stars from Small Magellanic Cloud and NGC104 populations
- Confirmation of Gaia's effectiveness in disentangling stellar populations along the line-of-sight

## Abstract

We explore the possibility of searching for extratidal features around the Galactic globular cluster NGC362 using the Gaia DR2 together with a modified version of a classical statistical decontamination algorithm. Our results suggest that an important stellar component is associated with this globular cluster, which is perfectly distinguishable from the populations in the Small Magellanic Cloud and that of the nearby NGC104 (47 Tucanae). We thus confirm once again the power of Gaia to disentangle different stellar components along the same line-of-sight.
