By F. Casoli,J. Lequeux,F. David

In those lectures, i've got mentioned a couple of simple strategies that supply the mandatory heritage to the present reports of superstar formation. A ?rst partwas dedicatedto illustrate the conceptofa protostar,discussing
con- tions and propertiesof the collapseof a molecular center. A secondpart offers with circumstellardisks. Disks areimportantnot basically to the processofstar formation itself, but additionally simply because they're very likely the site
the place planets shape. The age diversity of pre-main-sequence stars coincides with the timescales for the formation of very huge planetesimals, the development blocks of planets. stories ofdisk houses in pre-main-sequencestars
ofdi?erent age, positioned in star-forming areas of di?erent houses, may well make clear the features of planet formation methods. ISO observations grants very important (in a few situations, distinct) inf- mation on the
quite a few phases of the celebrity and planet formation. i've got illustrated intimately a few examples, while, to my wisdom, ISO information have been diminished and analyzed. Many different courses exist, and should definitely give a contribution to our
realizing of famous person formation within the close to future.
