一个近红外恒星光谱库:III。J带光谱

A Near-Infrared Stellar Spectral Library: III. J-Band Spectra

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

摘要:

本文是Ranade等人(2004 & 2007)发表的近红外(NIR)恒星光谱库系列论文的第三篇。这些观测是用1.2米的Gurushikhar红外望远镜(GIRT)进行的。Abu,India使用基于NICMOS 3 HgCdTe $256 \times 256$ NIR阵列的光谱仪。在论文I(Ranade et al. 2004)中,给出了135颗恒星在$\sim 16$分辨率下的H波段光谱;论文II(Ranade et al. 2007)中,给出了114颗恒星在$\sim 22$分辨率下的K波段光谱。目前正在公布的J波段资料库包括126颗恒星,光谱类型为O 5-M8,光度类别为I-V。这些光谱在J波段具有中等分辨率的$\sim 12.5$ 100 °,并根据各自的有效温度进行了连续形状校正。这套完整的近红外(NIR)库将为从事恒星星族合成领域的研究人员提供一个良好的数据库。J、H和K中的完整库可在线获得:http://vo.iucaa.ernet.in/ $\sim$ voi/NIR\_Header.html

英文摘要:

This paper is the third in the series of papers published on near-infrared (NIR) stellar spectral library by Ranade et al. (2004 & 2007). The observations were carried out with 1.2 meter Gurushikhar Infrared Telescope (GIRT), at Mt. Abu, India using a NICMOS3 HgCdTe $256 \times 256$ NIR array based spectrometer. In paper I (Ranade et al. 2004), H-band spectra of 135 stars at a resolution of $\sim 16$Å& paper II (Ranade et al. 2007), K band spectra of 114 stars at a resolution of $\sim 22$Åwere presented. The J-band library being released now consists of 126 stars covering spectral types O5--M8 and luminosity classes I--V. The spectra have a moderate resolution of $\sim 12.5$Åin the J band and have been continuum shape corrected to their respective effective temperatures. The complete set of library in near-infrared (NIR) will serve as a good database for researchers working in the field of stellar population synthesis. The complete library in J, H & K is available online at: http://vo.iucaa.ernet.in/$\sim$voi/NIR\_Header.html
