I would like to read an introduction text about how BH can be be formed, with a pure classical point of view (no quantum effects).(adsbygoogle = window.adsbygoogle || []).push({});

Is there some dynamic model of BH formation?

What are the main conclusions?

Is there a characteristic time for the appearance of a finite Scharchild radius? (as seen from far away from the BH)

Is there a known grow rate for some given initial mass density?

Or do these questions have little sense?

Any comment or refences welcome.
