If Sirius B is smaller than Jupiter, how did the fusion reaction get started?
My current understanding is that the critical mass required would have to be up around the Sun.
Did I miss a memo? Is it a white dwarf or some such?

(2,167 posts)If you go to the part which features Sirius B, you will see that they have it
relatively smaller than the gas giants of our Solar system.
Am I missing something?
