Near-Infrared Classification Spectroscopy: J-Band Spectra of Fundamental MK Standards | | Lloyd Wallace Michael R. Meyer Kenneth Hinkle Suzan Edwards
; | | Date: |
31 Dec 1999 | | Subject: | astro-ph | | Affiliation: | Kitt Peak National Observatory, NOAO) Michael R. Meyer (Steward Observatory, The University of Arizona) Kenneth Hinkle (Kitt Peak National Observatory, NOAO) Suzan Edwards (Astronomy Department, Smith College | | Abstract: | We present a catalog of J-band spectra for 88 fundamental MK standard stars observed at a resolving power of R ~ 3000. This contribution serves as a companion atlas to the K-band spectra published by Wallace and Hinkle (1997) and the H-band atlas of Meyer et al. (1998). We report data from 7400-9550 1/cm (1.05-1.34 microns) for stars of spectral types O7-M6 and luminosity classes I-V as defined in the MK system. In reducing these data, special care has been taken to remove time-variable telluric features of water vapor. We identify atomic and molecular indices which are both temperature and luminosity sensitive that aid in the classification of stellar spectra in the J-band. In addition to being useful in the classification of late-type stars, the J-band contains several features of interest in the study of early-type stellar photospheres. These data are available electronically for anonymous FTP in addition to being served on the World Wide Web. | | Source: | arXiv, astro-ph/0001546 | | Services: | Forum | Review | PDF | Favorites | |
