The relation between stellar chromospheric activity and rotation of evolution stars have a good relativity. but meticulous analysis show chromospheric activity of evolution stars depend on stellar spectral type and effective temperature strongly. we provide several possible explain for those phenomena
但是細致分析顯示演化恆星色球活動水平隨恆星自轉周期間的分佈對恆星光譜型和恆星表面有效溫度有很強的依賴,並對這些現象提出了幾種可能的解釋。Which will eventually form stars of spectral types g, k or m. t tauri stars are surrounded by a huge cloud and they are very young, with low surface temperature. they emit most of their light in the infrared region and they appear red. a general principle is, a violent reaction will give out short wavelength waves, like gamma rays or x - rays ; while a gentle process will radiate long wavelength waves, like radio or infrared
,這類星最後會演化為g k或m型恆星,金牛座t型星為表面溫度低而非常年青的恆星,四周被星雲所圍繞,所以這種星顏色偏紅,較容易在紅外線波段找到一個普遍的原則是,如果活動越激烈,則所放出的光波波長越短,主要會為伽瑪或x射線如果活動溫和,則會發放出如無線電波或紅外線等長波長電磁波。Is the most important diagram in discussing stellar evolution. it is a plot of the surface temperature versus the brightness or luminosity of stars
是研究恆星演化最重要的工具,它顯示了恆星表面溫度和恆星光度的關系。These two types of stars are so hot that most of their lights are emitted in the ultraviolet region
這兩類恆星由於表面溫度太高,所發出的光大部分屬紫外光。Therefore, the color of a star is mainly determined by its surface temperature, but its luminosity is determined both by its surface temperature and the surface area
所以,恆星的顏色由表面溫度所決定,而恆星的光度則由表面溫度和表面面積所決定。分享友人
