结果表明，在吸积引起的塌缩或白矮星的裸塌缩中裸露或近裸露中子星的诞生可以产生宇宙学伽马射线爆发，并可以提供所需的宇宙射线注入星际空间的速率。据估计，大多数 e(+)e(-) 对在中子星附近的短时间尺度飞行中湮灭。结果表明，伽马射线暴、0.511 MeV 银河湮没辐射和宇宙射线排除了银河脉冲星诞生率和银河 SN II 爆炸率的巨大不确定性可能对裸露或近裸中子星形成对脉冲星诞生率做出重大贡献的可能性。银河系裸露或近裸中子星的诞生率上限小于千分之一，这使得地下中微子望远镜不太可能在不久的将来探测到裸露或近裸中子星诞生时不伴随光发射的中微子爆发。
It is shown that the birth of naked or nearly naked neutron stars in accretion-induced collapse or in the bare collapse of white dwarfs can produce cosmological gamma-ray bursts and can provide the required injection rate of cosmic rays into the interstellar space. It is estimated that most of the e(+)e(-) pairs annihilate in flight on a short time scale in the vicinity of the neutron star. It is shown that the gamma-ray bursts, the 0.511 MeV Galactic annihilation radiation, and the cosmic rays exclude the possibility that the large uncertainties in the Galactic pulsar birthrate and the Galactic SN II explosion rate would allow a significant contribution to the pulsar birthrate from naked or nearly naked neutron star formation. The upper bound on the Galactic birthrate of naked or nearly naked neutron stars of less than 1 in 1000 yr makes it very unlikely that a neutrino burst unaccompanied by optical emission from the birth of a naked or nearly naked neutron star will be detected in the near future by underground neutrino telescopes.
