Cold Mass Accretion

(stellar accretion through an accretion disk)

Cold Mass Accretion (CMA) is a model of Protostar Accretion where the accreting material is from a disk and covers only a small portion of the stellar surface allowing most of the star to radiate freely. Hot Mass Accretion is where material accretes over much of the surface and affects radiation.
