生まれたばかりの星のことで、分子雲の中でもガス密度の高い分子雲コアが自己重力で収縮し始め、質量が一定のままサイズが収縮するTTS（おうし座T型星）やハービッグAe/Be型星となる前の状態のこと
A protostar is a newly forming star that is still pulling in material from the gas cloud around it, representing the earliest stage of star development. Protostars matter because studying them helps us understand how stars like our Sun form and evolve, starting from the collapse of a gas cloud and continuing until nuclear fusion begins.
