Discovered a new open cluster near the poorly studied Majaess 190
A. L. Tadross

TL;DR
This study reports the discovery and characterization of a new open cluster, Ash-1, near Majaess 190, using Gaia DR3 data, providing initial estimates of their properties and evolutionary states.
Contribution
The paper introduces Ash-1, a newly discovered open cluster, and presents its astrophysical properties along with those of Majaess 190, based on Gaia DR3 data and advanced membership analysis.
Findings
Ash-1 is approximately 1360 pc away and 630 Myr old.
Majaess 190 is about 2130 pc away and 4 Gyr old.
Both clusters are in a state of dynamic relaxation.
Abstract
We present the results of a comprehensive astrophysical study of a newly discovered open cluster, dubbed Ash-1. Using the third data release of the Gaia space mission, Gaia DR3, Ash-1 was accidentally discovered within the constellation Sagittarius in the field of the poorly studied cluster Majaess 190. Here we present the first estimates of these two clusters' primary astrophysical properties. The membership probabilities P>0.50 were assigned to both clusters using the pyUPMASK technique. The distances were determined using the parallaxes of the clusters' members, which were consistent with the isochrone fitting of the color-magnitude diagrams. The ages and distances of Majaess 190 and Ash-1 are found to be 4 Gyr and 630 Myr; 2130 and 1360 pc, respectively. The extinctions, heliocentric distances, mass function, luminosity function, and overall masses of the studied clusters were also…
