cds-question@unistra.frgiant-starseffective-temperaturechemical-abundancesline-intensitiesWe report the discovery of a lithium-rich giant, HD 150382, a post-red-giant-branch clump star. The atmospheric parameters, the chemical abundances for 17 elements, and the isotopic ratio ^12^C/^13^C were determined using the equivalent width and the spectral synthesis methods. The lithium abundance was determined via spectral synthesis of the Li I resonance doublet at {lambda} 6708 yielding log{epsilon}(Li)_NLTE_=2.55. The excited-state line at {lambda} 6104 also was analyzed. In addition, we have used theoretical evolutionary tracks to determine the mass and luminosity of HD 150382 and compare it with other well-known lithium-rich giants in the literature. Our results show that HD 150382 is a slowly rotating K-giant star having near-solar metallicity. We also show that HD 150382 is not s-process enriched, which is in agreement with its evolutionary status. Finally, based on the abundance results, we study the possible scenarios of the lithium enrichment.2020AJ....159....9Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/364/674 : Li-rich giants atomic lines (Castilho+, 2000)J/A+AS/142/275 : Stellar activity of late-type stars (Strassmeier+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/159/9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/159/9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/159/9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/159/9https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/159/9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/159/9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/159/9/table5 (Properties of the Li-rich giants adopted for comparison)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/9/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/9/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/9/table5?GETtext/xml+votable180.050000true250.2824914-11.83859970.0055555555555555566/1408 1782 2395 2839 3620 5255 7332 9350 10917 12083 12111 12449 14007 14336 15011 15137 15432 16034 16815 17444 17902 18471 19414 19824 21234 21307 21442 23010 28673 28745 28778 28823 29880 29951 30293 30295 30301 30464 30466 30472 30512 30693 30816 31812 33537 34075 36959 37229 37240 37317 37319 37787 37790 37933 39194 39216 39647 40140 41126 41639 41709 42101 43416 43806 45387https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/159/9?format=asciidefaultJ/AJ/159/9/table5Properties of the Li-rich giants adopted for comparisonSimbadNameSimbad column added by the CDSmeta.idcharNameStar namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
