Not really; the energy density in the core of our sun is about 100 watts / cubic meter. (Energy density is a LOT higher in more spectacular events, like supernova and the first few milliseconds of a hydrogen bomb's fun-time). Smaller stars burn fuel more efficiently. Our sun is good for about 4-6 billion years; a much smaller star will last several trillion years.
