The Event Horizon
Vaidya-Einstein- Kerr (VEK)
Vaidya-Einstein-Schwarzschild (VES) Set a = 0 above
Vaidya-Robertson-Walker (VRW)

Work Done
K. Rajesh Nayak, Malcolm MacCallum, CVVVES: Matched to Schwarzschild at horizon and to Einstein universe outside.
B.S. Ramachandra and CVV ; BSR, KRN, CVV Geometrical and physical properties of VES and VEK
P.S.Joshi and J.V.NarlikarBlack hole physics in globally hyperbolic spacetime with VRW as example.

What Next?
1. Match VEK to Kerr metric at the horizon. Cannot be matched at stationary limit.
2. VRW: Is the ‘horizon’ a null surface?
3. Further properties of the Vaidya black-hole spacetimes.
4. Explore Whittaker’s spacetimes with: Density +3 X Pressure=Constant( Non-zero).
5. Realistic models of black holes with matter.
