At increasing depths, their structure is expected to follow what has been dubbed the "pasta-antipasta sequence," as particles group first into meatball- like clumps, then spaghetti-like strands, then lasagna-like sheets.  
At increasing depths, their structure is expected to follow what has been dubbed the "pasta-antipasta sequence," as particles group first into meatball- like clumps, then spaghetti-like strands, then lasagna-like sheets.  Their atmosphere is approximately one meter thick, below which is a predominantly iron crust.  Anomalies in their rotation speeds are called glitches and are thought to be caused by starquakes. Their existence, first predicted by Zwicky, had strong existence provided by the discovery of the first pulsar in by Jocelyn Bell and Anthony Hewish.  Predicted to form when a star's core mass exceeds the Chandrasekhar limit, but is less than about three solar masses, FTP name these rapidly spinning remains of supergiants.
