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。In many stellar disks, observers also have found the spectral signature of silicate emission, indicating that small dust grains on the disk surface have been strongly heated by the stellar radiation
天文學家也發現了許多恆星氣盤具有矽的發射光譜,表示盤面上的微小塵埃顆粒已被恆星輻射強烈加熱。To search for high - velocity molecular emission toward massive star formation regions, and to study the connections between h2o masers, iras objects and outflow properties, we carried out a co observation for a h2o maser sample. we found that most of the objects have excess high velocity emission produced by outflows ; we find a significant correlation between co line full widths and iras luminosities. the widths are proportional to the iras luminosities
通過在大質量恆星形成區搜尋高速分子輻射,並且研究它們與星際h _ 2o脈澤源和所聯系的紅外源之間的關系,我們發現絕大多數源都存在著氣體的高速運動並且它們是由分子外流產生的;我們同時發現在co分子的譜線全寬和所對應源的紅外光度之間存在很好的相關性,線寬隨紅外光度增加而變大。This paper describes a new method to select these parameters, including to determine the focus length, relative aperture and field of view of new optical system in design by means of making reference to previous star sensors and their optical systems ; to forecast the acquiring probobility of star sensor in accordance with selected param eters ; to determine the principal design wavelength and spectral coverage by means of integrat ing the spectrum of stars
