1971 Morrison & Cavaliere in D. J. K. O'Connell Nuclei of Galaxies 487 By spinars we mean a class of bodies storing a considerable fraction of their total energy in a single, continuous degree of freedom—rotation... Pulsars are a very special subclass of spinars.
1977 Astron. & Astrophysics LVI. 166/2 We will consider..a supermassive oblique rotator (SOR) having solid-body rotation and quasi-dipole magnetic field. In the ‘cold’ version such a rotator coincides with a ‘spinar’ or a ‘giant pulsar’ proposed by Morrison.
1978 Nature 28 Sept. 282/1 The nonthermal radiation of a spinar can in some circumstances far exceed the thermal (Eddington-limited) component.
