This study presents a new atomic line list covering a broad spectral range (1-2.5um; YJHK bands) for iron (Fe) and {alpha}-elements (Ca, Mg, Ti, Si) to improve stellar parameter determination using near-infrared (NIR) spectroscopy. We highlight the limitations of existing line lists, stemming primarily from inconsistencies in oscillator strengths for ionized iron lines within the Apache Point Observatory Galactic Evolution Experiment DR17. The line list was validated using the high-resolution and high-quality disk-center NIR spectra of the Sun and its solar analog HD 76151. As a result of the spectroscopic analyses, the effective temperature of HD 76151 was calculated as 5790+/-170K, surface gravity as 4.35+/-0.18cgs, metal abundance as 0.24+/-0.09dex, and microturbulence velocity of 0.30^+0.5^_-0.3_km/s by combining the optical and NIR line lists. A comparison of the model atmospheric parameters calculated for HD 76151 with the PARSEC isochrones resulted in a stellar mass of , radius 1.125^+0.035^_-0.011_R_{sun}_ , and an age of 5.5^+2.5^_-2.1^Gyr. For the first time, kinematic and dynamical orbital analyses of HD 76151 using a combination of Gaia astrometric and spectroscopic data showed that the star was born in a metal-rich region within the solar circle and is a member of the thin disk population. Thus, the slightly metal-rich nature of the star, as reflected in its spectroscopic analysis, was confirmed by dynamical orbital analysis.2024ApJ...976..175Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/976/175CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/94/221 : New multiplet table for FeI (Nave+, 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/976/175https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/976/175http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/976/175https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/976/175https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/976/175http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/976/175GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJ/976/175/table2Stellar atmospheric parametersrecnoRecord number assigned by the VizieR team.
