The Strange Case of the Iron Sun: on Oliver Manuel and his alternative theory of the evolution of the Sun. He claims his research points to the Sun having evolved from the out of a supernova and that a neutron star still forms its nucleus. The technical details can be found on his site.
Manuel fits a popular stereotype, the lone dissenter promoting a new idea that flies in the face of the scientific establishment. In the real world, some of these theories eventually have been proven right but vastly more have been proven wrong. Manuel is under no illusions about the popularity of his idea. "Ninety-nine percent of the field will tell you it's junk science," he says. The evidence weighs in heavily against him. If he's right, however, we need to completely rethink how planetary systems form. Even if he's wrong, some scientists say, at least he has made people think.
