一个近红外恒星光谱库:II。K波段光谱

A Near-Infrared Stellar Spectral Library: II. K-Band Spectra

Arvind C. Ranade, Harinder P. Singh, Ranjan Gupta, N. M. Ashok

摘要:

本文是近红外(NIR)恒星光谱库系列论文中的第二篇,通过减少1.2米Gurushikhar红外望远镜(GIRT)进行的观测而产生。Abu,India使用基于NICMOS 3 HgCdTe 256 X 256 NIR阵列的光谱仪。在论文I(Ranade et al. 2004)中,给出了135颗恒星的H波段光谱,分辨率约为16 Angs。目前公布的K波段数据库包括114颗恒星,光谱类型为O 7-M7,光度类别为I-V。K波段的光谱分辨率中等,约为22 Angs,并根据各自的有效温度进行了连续体形状校正。我们希望尽快公布剩余的J波段光谱。完整的H和K波段库可在以下网址获得:http://vo.iucaa.ernet.in/~voi/NIR_Header.html

英文摘要:

This paper is the second in the series of papers on near-infrared (NIR) stellar spectral library produced by reducing the observations 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. In paper I (Ranade et al. 2004), H-band spectra of 135 stars at a resolution of ~16 Ang were presented. The K-band library being released now consists of 114 stars covering spectral types O7--M7 and luminosity classes I--V. The spectra have a moderate resolution of ~22 Ang in the K band and have been continuum shape corrected to their respective effective temperatures. We hope to release the remaining J-band spectra soon. The complete H and K-Band library is available online at: http://vo.iucaa.ernet.in/~voi/NIR_Header.html
