晚型星和大行星的近红外球载测光

0.96μm OBSERVATION OF LATE-TYPE STARS AND LARGE PLANETS WITH A BALLOON-BORNE IR TELESCOPE

本文给出1988年8月16日中日合作发放的10厘米球戴红外望远镜对亮晚型巨星、木星、火星和土星的观测结果。探测系统由硅光电二极管及HD820滤光片组成，有效峰值波长0．96微米，带宽0．23微米。文章介绍了扫描观测的处理方法和流量定标方法，给出所观测的恒星及行星在0．96微米上的视星等。

According to the cooperative plan for balloon-borne transocean flight between China and Japan, a 10cm IR scan telescope was launched in Aug. 16, 1988. The observational results for bright late-type stars, Jupiter, Mars and Saturn are presented. The detective system consists of a Si-diode and a HD820 filter. It had an effective peak wavelength of 0.96μm and a passband of 0-23μm. The methods of processing for observational data and of flux calibration are introduced, and visual magnitudes in 0.96μm for these stars and planets are given (Table 3). It is found that the flux from 0.44 to 1.65μm for most of these stars could be fitted with a blackbody spectrum,
