Hungry Millisecond Pulsar Found Feeding 15

    One says that the burn will be fast and explosive, blowing all the rest of the new, degenerate and normal matter off of the surface.
    Where'd that theory come from? I've been reading about neutron stars for some time and I've seen this as an explanation for X-ray bursters (the ignition of the accumulated hydrogen makes the surface extremely hot for a while, then it cools), but the star does not lose matter; the energy of fusing hydrogen is not sufficient to overcome the gravity of a neutron star.

    That sounds more like a certain theory for the collapse of white dwarfs under infalling matter. Supposedly this would always happen at the same mass and produce uniformly bright supernovae.

    Sounds like a sick snack, don't it.

    here's a link to Globular Cluster NGC6397 []

    Can you find the pulsar? *grin*
