 ===When does it stop being a YSO?===
+According to Wikipedia, a YSO (pre-main sequence) turns into a main sequence star when "nuclear fusion of hydrogen becomes the dominant energy production process and the excess energy gained from gravitational contraction has been lost."  I assume fusion could still occur in the pre-main sequence phase, but it is not the dominant source of energy.

 ===Why study YSOs?===
+If we know more about stars and star formation, we can learn more about what makes a star optimal for supporting life.  The earliest stages of a star's life often last the shortest amount of time, so we have the least amount of information on these stages.

 "Protostars are the most mysterious and exotic YSOs being so heavily embedded in surrounding gas and dust that they are invisible at the traditional optical wavelengths and can only be studied in the infrared, millimeter or sub-millimeter wavelength bands."
