In 2015, they held super-heated
hydrogen plasma in a
stable state for 5 milliseconds, which is a huge deal in the world of
fusion research.
The article discussing the possibility of generating energy using small - scale nuclear
fusion suggested that both deuterium and tritium are
stable isotopes of
hydrogen.
When their central temperatures reach values comparable to 107 K,
hydrogen fusion ignites in their cores, and they settle down to long
stable lives on the main sequence.
The young star is now
stable in that the outward pressure from
hydrogen fusion balances the inward pull of gravity.
The outward pressure from
fusion counteracts the inward pressure from gravity and an equilibrium point was reached where they are equal and opposite in force and the sun has a relatively
stable diameter that will persist until it starts running out of
hydrogen fuel to sustain the outward pressure.
