Search for red dwarfs among X-ray objects of the deep survey of the equatorial region of the sky using eROSITA data

TL;DR

This study identifies potential red dwarf stars among X-ray sources in the eROSITA deep survey of the equatorial sky, highlighting 110 candidates and providing detailed catalog data.

Contribution

It introduces a method for identifying red dwarf stars among X-ray sources using eROSITA data, including a catalog of candidates and analysis of their properties.

Findings

110 candidate red dwarfs identified among 27,910 X-ray objects

12 previously classified X-ray sources confirmed as stars

Some identifications involve closely spaced objects or galaxies

Abstract

The paper presents the identification of the stars in the lower part of the Main Sequence among the objects of the deep survey of the equatorial region of the sky, performed by the eROSITA telescope at the SRG orbital observatory. Of the 27,910 X-ray objects, 110 are possibly candidates for identification with red dwarfs. 12 stars were previously classified as X-ray sources. In the area of identification of two stars, galaxies fall. Several identifications contain closely spaced objects. The list of identified objects, comments to it and search maps are given in the appendices.
