The Observer`s Guide to the Gamma-Ray Burst
... The luminosity, energetics and shape of the γ-ray pulse of a given GRB can reveal clues to the origin of its high-energy emission, and thus its emission process. Of particular importance is whether the γ-rays emitted by llGRBs arise from the same mechanism as high-luminosity GRBs (i.e. from a jet), ...

The Evolution of Protostars - Max-Planck
... How do we distinguish various stages in protostellar evolution? Theoretically, a collapsing core initially forms a first hydrostatic core, which quickly collapses again to form a true protostar, referred to as Stage 0. As material moves from the surrounding core to the disk and onto the star, the st ...
