cds-question@unistra.frinfrared-astronomyspectroscopystellar-spectral-typesradial-velocitymetallicityline-intensitiesWe present a library of high-resolution (R~45000) and high signal-to-noise ratio (S/N>=200) near-infrared spectra for stars of a wide range of spectral types and luminosity classes. The spectra were obtained with the Immersion GRating INfrared Spectrograph covering the full range of the H (1.496-1.780{mu}m) and K (2.080-2.460{mu}m) atmospheric windows. The targets were primarily selected for being MK standard stars covering a wide range of effective temperatures and surface gravities, with metallicities close to the solar value. Currently, the library includes flux-calibrated and telluric-absorption-corrected spectra of 84 stars, with prospects for expansion to provide denser coverage of the parametric space. Throughout the H and K atmospheric windows, we identified spectral lines that are sensitive to Teff or logg and defined corresponding spectral indices. We also provide their equivalent widths (EWs). For those indices, we derive empirical relations between the measured EWs and the stellar atmospheric parameters. Therefore, the derived empirical equations can be used to calculate the Teff and logg of a star without requiring stellar atmospheric models.2018ApJS..238...29Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/238/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : SB9: 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)III/114 : Spectra of Late-Type Standards, 2.0-2.5 Microns (Kleinmann+ 1986)III/149 : MK Standard Stars (Garcia 1989)III/196 : Near-IR stellar spectra from 1.428 to 2.5 um (Lancon+ 1996)III/200 : Catalogue of [Fe/H] (Cayrel de Strobel+, 1997)III/221 : Catalogue of [Fe/H] of F, G, K stars (Cayrel de Strobel+, 2001)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+AS/116/239 : H band stellar spectra (Dallier+, 1996)J/ApJ/469/355 : Teff, B-V and BC relation (Flower, 1996)J/ApJS/107/281 : Atlas of hot, luminous stars at 2 microns (Hanson+ 1996)J/A+AS/123/473 : Late-type star spectra (Montes+ 1997)J/ApJ/508/397 : H-band Spectral Standards (Meyer+ 1998)J/A+AS/128/485 : Library of UES spectra late-type stars (Montes+ 1998)J/A+AS/137/521 : 8500-8750{AA} high resolution spectroscopy (Munari+, 1999)J/ApJS/141/503 : Radial Velocities for 889 late-type stars (Nidever+, 2002)J/A+A/406/995 : 8500-8750{AA} high resolution spectrosc.
