I'm hoping to commission some calculations, but before tossing my dosh to the winds, I'd be glad of some feedback from my fellow astronomy enthusiasts.
Please let me know if you think it is possible to base calculations on the following parameters and or if not, why.
It might help if you think of this as an abstract exercise, rather than something actual.
1. Calculate the mass necessary to inaugurate nuclear fusion in a classic proto-sun model. (Sliding parameters, if necessary)
2. For a template, place the proto-sun in the center of our solar system.
3. Extrapolate the speed of proto-sun's angular momentum, determining its rotation using Saturn's (10 h 32 – 47 min) and Jupiter's rotations (9.925 h) as benchmarks. (Sliding parameters, if necessary)
4. Distributing the mass of the proto-sun in an expanding shell, "inflate" the proto-sun until its angular momentum matches that of our Sun (25-30 days)
5. The expanded proto-sun size required.
Let me know if you think this calculation is possible, in advance, thank you.
