A near-infrared stellar spectral library; I. H-band spectra

Abstract

This paper presents the H band near-infrared (NIR) spectral library of 135 solar type stars covering spectral types O5-M3 and luminosity classes I-V as per MK classification. The observations were carried out with 1.2 meter Gurushikhar Infrared Telescope (GIRT), at Mt. Abu, India using a NICMOS3 HgCdTe 256 x 256 NIR array based spectrometer. The spectra have a moderate resolution of 1000 (about 16 A) at the H band and have been continuum shape corrected to their respective effective temperatures. This library and the remaining ones in J and K bands once released will serve as an important database for stellar population synthesis and other applications in conjunction with the newly formed large optical coude feed stellar spectral library of Valdes et al. (2004). The complete H-Band library is available online at: http://vo.iucaa.ernet.in/~voi/NIR_Header.html
