cds-question@unistra.fratomic-physicsspectroscopychemical-abundancesb-starseclipsing-binary-starsWe present a new practical atomic line list for the optical and near-infrared spectral regions (3850-8220{AA}), specifically tailored for the spectroscopic analysis of hot B-type stars. Compiled through careful merging and expansion of established literature sources, this list addresses the critical lack of comprehensive and homogeneous atomic data for hot star spectroscopy. The line list was rigorously validated using high-resolution HERMES and UCLES spectra of the benchmark star HR 1765 and FOCES spectra of the Algol-type binary system u Herculis. By performing a homogeneous local thermodynamic equilibrium (LTE) abundance analysis with literature stellar parameters, we successfully reproduced the published results for the single star HR 1765 and obtained a revised abundance pattern for the mass-gaining primary component of u Her. A key aspect of our methodology is the subsequent application of NLTE calculations for several key species (He, Ne, and Si). The spurious helium enrichment suggested by LTE for HR 1765 was resolved, yielding an NLTE abundance consistent with the local cosmic standard, thereby mitigating the systematic biases inherent in the LTE approach and yielding abundances consistent with the cosmic standards. The results for u Her confirm the presence of CNO-processed material on its surface, which is characterized by nitrogen enrichment and carbon depletion. The expanded coverage of our line list enabled the first spectroscopic detection of ClII in HR 1765 and the first measurement of Ne abundance in u Her. Furthermore, we report the first abundance determination of PIII, SII/III, ArII, and FeIII in u Her. The consistency of our results with those of previous studies employing different methodologies underscores the robustness and reliability of the compiled line list, establishing it as a valuable and readily applicable resource for future spectroscopic studies on hot stars, particularly in the context of interacting binary systems.2026PhyS..101d5004Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PHYS/101.D5004CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/PHYS/101.D5004https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/PHYS/101.D5004http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/PHYS/101.D5004https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/PHYS/101.D5004https://vizier.iucaa.in/viz-bin/votable?-source=J/other/PHYS/101.D5004http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/PHYS/101.D5004GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/other/PHYS/101.D5004/blinesCurated atomic line listrecnoRecord number assigned by the VizieR team.
