"The trick would be getting a nuke to penetrate deep enough into the sun’s photosphere without being vaporized by the high temperatures and pressure. The explosion then needs to be powerful enough to cause a chain reaction in the hydrogen of the sun that propagates faster than the shock wave from the explosion. This could only be done using a thermonuclear device which would need to be at least 0.5 MT"
"It would require massive advances in technology though from current levels to get a thermonuclear device far enough into the photosphere of the sun that it has enough hydrogen around to maintain a chain reaction at a fast enough speed to spread faster than the shock wave from the explosion. Very very very difficult, but yes, it may be possible to blow up the sun to a certain extent. This would be a Nova however, not a Supernova. We would only know if it is viable after significant supercomputer modelling has been done, and then it may take decades or longer to be able to develop the technology to deliver a thermonuclear device to a deep enough depth within the suns photosphere. It may not be possible with our star but it seems likely that some starts in the galaxy would be quite susceptible to this."
"Brown Dwarf stars would probably be much easier targets and by the time we have the technology to visit other stars we would possibly have the technology to create effective Nova Bombs for use on certain stars like Brown Dwarf’s."
