cds-question@unistra.frlate-type-starsinfrared-sourcesline-intensitiesThe near-infrared (NIR) wavelength range offers some unique spectral features, and it is less prone to the extinction than the optical one. Recently, the first flux calibrated NIR library of cool stars from the NASA Infrared Telescope Facility (IRTF) have become available, and it has not been fully exploited yet. We want to develop spectroscopic diagnostics for stellar physical parameters based on features in the wavelength range 1-5um. In this work we test the technique in the I and K bands. The study of the Y, J, H, and L bands will be presented in the following paper. An objective method for semi-empirical definition of spectral features sensitive to various physical parameters is applied to the spectra. It is based on sensitivity map - i.e., derivative of the flux in the spectra with respect to the stellar parameters at a fixed wavelength. New optimized indices are defined and their equivalent widths (EWs) are measured.2013A&A...549A.129Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/326/959 : Near-IR Ca triplet empirical calibration (Cenarro+ 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A129https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/549/A129/table3 (Physical parameters of the stars of the NASA Infrared Telescope Facility (IRTF) library)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A129/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A129/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A129/table3?GETtext/xml+votable180.050000true20.02041758.2316110.0055555555555555566/4 248 254 320 349 399 679 684 725 749 754 841 905 1015 1297 1399 1603 1719 1737 1923 2127 2476 2598 2622 2755 2880 2940 2970 3031 3087 3230 3256-3257 3343 3469 3623 3634 3715 3719 4347 4444 4614 4719 4775 5000 5009 5068 5154 5253 5299 5420 5522 6066-6067 6182 6726 7178 8297 8402 8767 8794 8834 9083 9146 9460 9753 9843 9968 10375 10899 11016 11204 11292 11403 11473 12725 12770 12844 12877 12987 13007 13158 13166 13301 13725 13799 13803 14064 14110 14180 14253 14259 14278 14314 14357 14425 14522 14633 14689 14696 14709 14779 14968 15106 15156 15160 15384 15633 15650 15660 17283 17387 17716 18060 18364 18450 18683 18859 18998 19064 19323 19417 19761 19802 19857 20110 20178 20220 20896 21224 21296 21317 21440 21580 21601 22014 22125 22204 22220 22309 22420 22538 22807 22813 22861 23177 23274 23344 23523 23535 23611 23735 23850 24377 24396 24419 24486 24522 24920 24924 25015 25408 25864 25869 25930 26210 26228 26345 26457 26654 26688 26952 26975 27204 27457 27462 27752 28008 28257 28277 28487 28605 28696 28911 29037 29084 29102 29183 29657 29926 30293 30297 30505 30616 30660 30709 30833 31933 31987 32271 32619 32661 33767 34535 38322 39776 40635 40641 40885 40932 40941 43966 44129 44728 44807 44921 44942 44981 44993 47052 49013 49065https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A129?format=asciiInfrareddefaultJ/A+A/549/A129/table3Physical parameters of the stars of the NASA Infrared Telescope Facility (IRTF) librarySimbadNameSimbad column added by the CDSmeta.idcharnullableWmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
