After the TMA-2's compressed Jupiter into a star in Arthur C Clarke's 2010, how long would the star last

Question

The TMA-2's turned Jupiter into a star by compressing the matter that was there by building new TMA-2's from the planet's material. This resulted in an exponential consumption of the planets mass since the new TMA-2's took in more mass and then replicated. As a planet is compressed, its gravitational force goes up -- force = GMm/r^2 where r is the radius of the planet. As you can see, the smaller the radius the higher the gravity. If you make it small enough it will provide enough force to fuse hydrogen (which Jupiter has plenty of). Something similar was done in "Imperial Earth" when they created microscopic black holes. Ok, now that Jupiter has been compressed small enough to start a fusion reaction, would it be stable or just burn out rapidly. How long would it last?

Answer 1

I think the additional gravity would first absorb the asteroid belt and most of saturn. This would increse Jupiter's mass and the gravitational attraction between it and the sun would soon overcome Jupiter's rotational energy the two would fuse. This would probably take atleast 100 years, probably more like 200 or 300. I don't know how long it would last otherwise.

Answer 2

First i ought to assert that my interpretation of the movie is that the monoliths extra mass to Jupiter, which brought about it to settlement from the gravity, and not in any respect that they used some type of stress to compress the mass that grow to be already the following. that is because I actually have study the Jupiter is as large as a planet would properly be and including any mass would easily make it shrink from the added gravity. Now, to respond to your question, Jupiter will be compressed all the thanks to grow to be a black hollow if sufficient stress were accessible. yet when it were compressed to any volume short of that, it would spring again once the compression grow to be bumped off. till more beneficial mas were extra. a lot more beneficial. a number of time the present mass of Jupiter more beneficial.
