Pulsars are good clocks in the Universe. They have many applications. I am mainly interested in why pulsars are good clocks. I want to know (1) the spindown mechanism of pulsars, (2) the origin of their multiwave radiations (including radio & optical/IR & X-ray & gamma-ray etc). I am especially interested in a special kind of pulsars, i.e. magnetars (and related objects, including XDINSs, CCOs, HBPSRs etc).

Twinkle Twinkle little pulsar, how I wonder what you are!

I do not know whether you are a neutron star or a quark star.

At present the only thing I aware

All pulsars are not magnetars.
