As I was reading your message, just the thought what other phenomenons we may (and WE WILL) find out there (and we barely 'scratched' the surface) got my mind and thoughts 'spinning'...
I'm just a bit worried, that an important paradigm shifted for 180 degrees in the last decades.
Nowadays, it is not so the lack of information that prevents us from making conclusions or confirming practically 'everyday' new emerging theories and hypothesis about our Universe with observations (thanx to the exponential rise of technology - think for example of the LHC and CERN -, sadly we can not say the same for our wisdom, which can't follow this pace, by simple rules of evolution... - but that belongs in the field of philosophy, and I'm again off the topic :-) BUT somewhat ironically, we now 'struggle' with way too much information, that has not only to be processed but also double or triple checked, a problem, which brings a whole new set of problems and slows us down.
Anyway:

I'm always a bit boggled by these objects : mass about that of the Sun ( give or take ), around 20km in diameter, a stupendous magnetic field,...
I wanted to ask you, are you reffering to magnetars with this statement, where not only the mass Vs. diameter is mind boggling but also the unimaginable high magnetic field associated with them.
I wonder, does this project also look for this phenomenons (and if yes, does it (sub)classify them under this name) as there is (at least to my knowledge) at least one crucial difference to 'regular' pulsars (sorry for the poor choice of words...):
The rotational period being much longer, as I have read, from 1 to as much as 10 seconds.
Regards.

P.S.
The more I know (although this knowledge is tiny to say at least), more curious I get - in this case, I have thank to you Mike, that this curiosity (by the 'courtesy' of an excellent answer) made a 'quantum' leap forward, not the opposite (something that I sometimes really experienced).

This is what happens to many contributors, myself included! :-)

Well projects like E@H using the distributed computing mechanism are breaking ground by matching researcher's needs for heavy duty processing - via donation of resources they couldn't otherwise afford - with the general public's natural curiosity and helpfulness in fascinating areas of study. The really neat thing I like about E@H is how unifying and inclusive it is, as anyone suitably equipped can participate.

Yes. There are lots of labels in the field, not necessarily mutually exclusive, and most are descriptive of a significant feature of interest. So even the term 'neutron star' is approximate, as it is a generic title for objects not quite massive enough to create an event horizon. It's not a bad label : you do get neutrons if you force electrons to combine with their atomic nuclei. But what's really inside them? Layers of quarks ? Who can say?
[ But being scientific one iterates between theory and observation in an endless cycle - that, by the way is the most commonest misunderstanding of science : it is only absolute in it's reference to reality, theory is always the slave to that. Too many think that science consists of deciding what you want and then allowing only what fits to be seen at all. ]

The repetition period is one discriminator and an important one too. All this energy that they spray around has to come from somewhere - their rotation slows and the hose dries up too. There is even a concept of 'recycling' : reactivation of pulsing behavior by those that had previously gone quiet ( this process is well beyond human lifetimes and thus suffers the standard problem of observation in astronomy, that being we only have seen but the briefest of time 'in the garden' ).

You're welcome!
