摘要：
We present K-band spectroscopy for several regions of three nearby spiral galaxies, NGC 613, NGC 628 and NGC 7741. Analysis of the depth of the 2.293 mu m CO absorption feature in these spectra reveals that some regions have deep absorptions, indicative of recent star formation, while others have anomalously shallow absorptions. We interpret the latter as evidence for a significant but localised contribution to the 2.3 mu m light from hot dust with an effective temperature of similar to 1000 K, which could have a significant effect on the K-band morphologies of star-forming galaxies.
