VizieR Online Data Catalog: Age estimates for NGC 2024 and ONC stars (Getman+, 2014)
Abstract
The MYStIX project has produced rich stellar samples of 31784 probable members of 20 OB-dominated young star-forming regions at distances 0.4-3.6 kpc using sensitive X-ray, NIR, and mid-infrared photometric catalogs (Feigelson et al. 2013, J/ApJS/209/26). Based on the MYStIX data, G14 developed a new PMS stellar age estimator, AgeJX. This estimator is based on J-band stellar photospheric emission and on X-ray emission from coronal magnetic flaring, and relies on an assumption of a nearly universal LX-M relationship for ~<5 Myr old PMS stars (Section 3.1 in G14).
