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。 -
