星冕活動 的英文怎麼說
中文拼音 [xīngmiǎnhuódòng]
星冕活動
英文
coronal activity-
The corona activity of late - type ms stars exist a inflexion nearby f5. there have two fold reason
分析結果顯示f型主序星的冕球活動在光譜型f5附近存在拐點。Between chromospheric activity index and corona activity index of ms stars, there exist good linear relativity. but for evolution stars, this relation show a large dispersion
我們發現主序星的色球與冕球磁活動指數存在著很好的線性相關性,而演化恆星的則表現出較弱的相關性。Though this departure is not obvious, the result still support the conclusion in the analysis of stellar chromospheric activity. for evolution stars, wo do n ' t, obtain significative result because the deficient samples. but the statistics analysis show the distrbution of corona activity of late type with color index and rotation period exist upper limit
演化恆星的磁冕球活動在色指數和自轉周期的分佈上都顯示出冕球磁活動存在上限的現象,並且對冕球磁活動上限的擬合表明在色指數b一v為1 . 0附近和自轉周期We have collected a mass of stellar activity and rotation data of late - type stars. combining with the results of hipparcos satellite, we reserch the relation between stellar activity and rotation ( include rotation period and rossby number ), and discuss the distribution of stellar rotation period and the evolution of angle momentum of late - type stars
因此,我們收集了晚型恆星的色球和冕球活動的指數以及恆星自轉方面研究發表的大量的觀測資料並結合hipparcos衛星的觀測結果,對晚型恆星的磁活動與恆星自轉間的相關性進行細致的研究。The result of statistics show the ratio of strong activity samples in m type ms stars is larger than that in other g, k type ms stars, the relation of between angle momentum and magnetic momentum of m type stars also depart from the whole relation of ms stars
主序星的角動量與以冕球活動指數為指標的磁動量間的相關性分析表明m型主序星的角動量與磁動量間的關系偏離了其它類型的主序星的總體線性關系。The corona activity of g, k, m type stars decrease with color index increasing as a whole
但是m型主序星的冕球活動是隨色指數的增大而下降,這與m型主序星色球活動的行為相反。This phenomenon farther surport our conclusion in the analysis of evolution stars, i. e. the difference of stellar chromosphere and corona activity of evolution stars is bred by the energy balance and heating mechanism in stellar chromosphere and corona
M型主序星在演化恆星的冕球活動與色球活動行為的差異則是由於m型主序星的色球與冕球間存在的能量平衡和轉移過程產生的。The corona activity of late - type main sequence stars also depend on the stellar spectral type
晚型主序星的冕球活動也表現出對恆星光譜型的依賴性。分享友人
