Let's be honest here, the increase in temperature from the nuke might be insufficient and the density too low to create a efficient burn-up, a self-sustaining reaction is a outrageous claim.

heroeblaster , the fission reaction you might be thinking of is the beta plus decay of Helium-2 to Deuterium after the initial proton-proton fusion reaction, which Wikipedia states has a significantly lower probability of occurring than the proton decay of Helium-2 to two protons. To quote verbatim; "The first step involves the fusion of two 1H nuclei (protons) into deuterium, releasing a positron and a neutrino as one proton changes into a neutron. It is a two-stage process; first, two protons fuse to form a diproton: 1H + 1H → 0He followed by the beta-plus decay of the diproton to deuterium: 0He → 2H + e++ νewith the overall formula: 1H + 1H→ 2H + e++ νe + 0.42 MeV This first step is extremely slow because the positron emission of the diproton to deuterium is extremely rare (the vast majority of the time, the diproton decays back into two hydrogen-1 unbound protons through proton emission). This is because the emission of the positron is brought about by the weak nuclear force, which is immensely weaker than the strong nuclear force and the electromagnetic force."Also relevant: "The half-life of a proton in the core of the Sun before it is involved in a successful proton-proton fusion is estimated to be about one billion years, even at the extreme pressures and temperatures found there."To be honest, using thermonuclear warheads to screw with the solar fusion rate sounds kind of outrageous, but I'm no expert. Yes, that's what I meant. I am not sure you could even force hydrogen to fuse fast unlike deuterium due to that.

EDIT: we can still add a nuke on RKV even the vehicle itself can't do all the things itself. That would be like adding a .22 derringer to a Tsar Bomba

Speaking of insane ideas, how about dropping planet nine into the Sun? It's entirely feasible, if you think about it - you only need to get rid of ~500 m/s of orbital velocity, and ice giants should have sufficient reaction mass. Plus, ~10 earth masses crashing into the Sun at >500 km/s will make for one helluva boom.
