2. The Vaidya Metric and Gravitational Collapse
Pankaj S. Joshi

12. An Explicit & Transparent Model
We can work out all the Parameters of the Solution fully explicitly
The Curvature growth, the Null and also Timelike Geodesics and all can be Fully Worked Out
Thus we get a clear picture of Gravitational Collapse Final States in this model collapse scenario
Helped Greatly to Settle a Very Important
Issue of Principle...

13. The Rate of Collapse plays a Major Role in deciding the Black Hole or Naked Singularity Outcome for Gravitational Collapse In Realistic collapse of Massive Stars, will Accretion Rate decide the Final Fate of the Star?
