I am not sure if we understand formation process of such stellar objects in general (Or possibly many processes). According to wikipedia one theory is slow orbit degradation of binary system containing neutron star and red dwarf: http://en.wikipedia.org/wiki/Thorne%E2%80%93%C5%BBytkow_object http://en.wikipedia.org/wiki/Thorne%E2%80%93%C5%BBytkow_obje...
