Test

This dataset provides comprehensive, validated parameters for Gaia DR3 2677448007190525696, a confirmed extremely metal-poor halo star ([Fe/H] = -4.12 ± 0.15). The object is classified as a Carbon-Enhanced Metal-Poor (CEMP-no) star showing abundance patterns indicative of early supernova enrichment. The data include fundamental atmospheric parameters, kinematics, and chemical abundances, validated through multiple independent methods and sources (APOGEE DR17, SAGA Database, Gaia DR3). Key characteristics:- Population II member (age ~13.5 Gyr)- Retrograde orbit (e = 0.92)- CEMP-no classification- Early supernova enrichment signature Validation metrics:- Data confidence level: 98%- Inter-source consistency: 96%- Error probability: <1% This repository contains:1.
