A supernova is observed by the chinese and amerindians near the star tauri 1054年的今天,一顆位于金牛座附近的超新星被中國及印第安人發(fā)現(xiàn)并記載。
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 ,這類星最后會演化為g k或m型恒星,金牛座t型星為表面溫度低而非常年青的恒星,四周被星云所圍繞,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(fā)放出如無線電波或紅外線等長波長電磁波。
