Description:
This directory contains movies in mpeg format which show models for the
time evolution of the Hertzsprung-Russell diagram of a very young open
cluster between 0 and 30Myr. Four different star formation scenario's
are considered, (a) instantaneous star formation, (b) constant rate of star
formation with time, (c) increasing rate of star formation, and (d)
decreasing rate of star formation. For the latter three scenario's, models
for a duration of the star formation episode δt of 0.1, 1.0 and 10Myr
are computed.
