# Polarimetry narrows down the possibilities for the Dusty S-cluster Object (DSO/G2) in the Galactic centre

## TL;DR

Polarimetry observations suggest the DSO/G2 near the Galactic centre is likely a non-spherical young star with a bow shock, narrowing down its possible nature.

## Contribution

This study uses polarimetry data to constrain models of the DSO/G2, proposing a young star with a bow shock as the most plausible explanation.

## Key findings

- The DSO/G2 is intrinsically polarized, indicating a non-spherical shape.
- Polarimetry constrains models, favoring a young star with a bow shock.
- Further observations are needed for definitive confirmation.

## Abstract

There have been many speculations about the character of the dusty object moving fast in the vicinity of the Galactic centre black hole. The recent detection of polarized continuum emission provides new constraints for the models. The fact that the object is intrinsically polarized implies that it is non-spherical. The authors propose that a young star developing a bow shock can explain the main characteristics. However, more observations in the future are needed for the final confirmation of the nature of the source.
