Protoplanets around Pulsars?
This is interesting...
Deepto Chakrabarty et al have Spitzer observations showing a debris disk around a young pulsar consistent with a protoplanetary fall-back disk post-supernova. (Damn, I wish I'd been on that SSU...)
Been speculated about for decades, nice to see; guess we have to take timing anomalies in young pulsars seriously now.
But, I don't think it is directly relevant to either of the known pulsar planet systems PSR 1257+12 or PSR1620-26, I could be wrong, but three planet formation mechanisms just for pulsar systems. Ouch.
