Warm IRAS sources. II.

We present optical spectra for a sample of 563 high-latitude IRAS sources selected from the Point Source Catalog to have relatively warm 25 to 60 micron colours. We have shown...本研究给出了563个高纬度红外天文卫星（Infrared Astronomical Satellite，IRAS）源样本的光学光谱数据，该样本从点源目录（Point Source Catalog）中筛选而来，其源均具有相对偏暖的25至60微米红外颜色特征。我们已证实……
