Protostellar mass radius relations for accretion
rates of 10-5 M? yr-1 (left, Palla Stahler
1991) and 10-5 M? yr-1 and 10-4 M? yr-1 (right,

Theoretically-computed birthline (heavy line)
along with evolutionary tracks for stars of fixed
mass (thin lines) and observed young stars
(points). Evolutionary tracks before the
birthline represent stars that are still
accreting (Palla Stahler 1990).
