A binary star may, or may not, be related to a nova or supernova. In some specific cases, a supernova is specifically caused by a close binary system; but not all binary systems result in novas, and not all novas come from binary stars.

A binary star can produce a nova when one star in the binary system accretes material from its companion, causing a sudden increase in nuclear reactions and a release of energy that leads to a temporary brightening of the system. This can occur when the accreted material ignites on the surface of the star in a runaway nuclear reaction.

A nova (as distinct from a supernova) is produced in a close binary system where one member is a white dwarf and the other a larger, less dense star. The white dwarf 'sucks' gas from the larger star which condenses into an accretion disc around the white star's equator. When this accretion disc reaches a critical mass it interacts with material on the white star and produces a huge thermonuclear explosion. This is what we see as a nova event. Novae are variable stars.
An X-ray burst in a binary system and a nova both involve explosive nuclear processes, but they occur in different contexts. In an X-ray burst, material from a companion star accumulates on the surface of a neutron star, leading to rapid nuclear fusion that releases intense X-ray radiation. In contrast, a nova occurs in a binary system where a white dwarf accretes hydrogen from a companion star, resulting in a thermonuclear explosion on the surface that ejects material into space. Both phenomena highlight the dynamic interactions in binary systems, but they differ in their specific mechanisms and the types of stars involved.

Nova. "Exploding stars" were originally called "new stars", which in Latin is "nova stellarum".

I believe it is about 120 mph.
