View Full Version : A blitzar every ten seconds?

The Wikipedia article gives a model for blitzars as neutron stars massive enough to form black holes, except they are spinning fast enough to hold up. When they despin enough...shloop!
It also estimates one every ten seconds.
As a model of BH formation, I would think this would be rarer than hypernovae or even neutron star collisions. From fast and slow GRBs, I understand these two events occur about once a day.
Are we missing a lot of GRBs (because they are directional, perhaps) or are blitzars way more common than my gut feeling implies?
