拱星 meaning in Chinese
circumpolar star
Examples
- The infrared carbon stars , whose infrared spectra are mainly due to the dust emission in the circumstellar envelope , are usually believed to be surrounded by the carbon rich envelope characterized by the sic emission feature at 11 . 3um
红外碳星常被认为有很厚的富碳拱星壳层，它的红外光谱主要表现为源于拱星壳层的尘埃发射，这个尘埃发射主要以11 . 3 m的sic发射为标记。 - Visual carbon stars whose mid - infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um , represent a transition phase which follows an interruption of mass loss from the oxygen - rich phase and begins a new phase of the mass loss of carbon - rich material . excesses at 60um in these stars are the emission from the residual of oxygen - rich material
光学碳星的中红外能量主要来自光球，在60 m处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60 m超量发射就是富氧物质的残余效应。
