The outer regions of a protostar form
Webb11 apr. 2024 · Webb's landscape-like view, called "Cosmic Cliffs," is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. The … Regardless of the details, the outer surface of a protostar consists at least partially of shocked gas that has fallen from the inner edge of the disk. The surface is thus very different from the relatively quiescent photosphere of a pre-main sequence or main-sequence star. Visa mer A protostar is a very young star that is still gathering mass from its parent molecular cloud. The protostellar phase is the earliest one in the process of stellar evolution. For a low-mass star (i.e. that of the Visa mer Star formation begins in relatively small molecular clouds called dense cores.
