cds-question@unistra.fra-starsline-intensitiesspectroscopyinfrared-astronomyWe present a catalog of absorption lines in the z', Y, and J bands that we identified in 21 Lyn, a slowly rotating A0.5V star. We detected 155 absorption features in the high-resolution (0.90-1.35um, R=28000) spectrum obtained with the WINERED spectrograph after the telluric absorption was carefully removed using a spectrum of a B-type star as a telluric standard. With a visual comparison with synthetic spectra, we compiled a catalog of 219 atomic lines for the 155 features, some of which are composed of multiple fine structure lines. The high-quality WINERED spectrum enabled us to detect a large number of weak lines down to ~1% in depth, which are identified for an A-type star for the first time. The catalog includes the lines of H, C, N, O, Mg, Al, Si, S, Ca, Fe, and Sr. These new lines are expected to be useful for spectral classification and chemical abundance analyses, while the line catalog is useful for observers who plan to use A-type stars as telluric standards because it is necessary to distinguish between stellar lines and telluric absorption lines in high-resolution spectra. ASCII versions of the spectra are available in the online version of the journal.2018ApJS..239...19Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/239/19CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/99/135 : Rotation and Spectral Peculiarities (Abt+ 1995)J/ApJS/124/527 : Oscillator strengths for lines in J & H bands (Melendez+,J/A+AS/137/521 : 8500-8750{AA} high resolution spectroscopy (Munari+, 1999)J/ApJ/535/325 : Spectra of normal stars in the J-band (Wallace+ 2000)J/A+A/585/A143 : NIR spectroscopy of the Sun and HD20010 (Andreasen+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/239/19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/239/19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/239/19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/239/19https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/239/19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/239/19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJS/239/19/table3Measurement of the absorption features in 21 LynrecnoRecord number assigned by the VizieR team.
