We analyze the gravitational waves within the Spinor Theory of Gravity and compare it with the General Relativity proposal. In the case of STG a gravitational wave may occur if the effective gravitational metric induced by the spinorial field is Ricci flat. 



The plane-fronted gravitational waves

This paper is a contribution to the theory of pure radiation in General Relativity. It gives a survey of the radiation fields which possess a twistfree and non-expanding null congruence, and

Rotating Neutron Stars as the Origin of the Pulsating Radio Sources

The constancy of frequency in the recently discovered pulsed radio sources can be accounted for by the rotation of a neutron star. Because of the strong magnetic fields and high rotation speeds,

On the possibility of stable quark and pion-condensed stars

The conditions for the appearance of stable quark stars and pion-condensed stars are analysed. On the basis of recently suggested equations of state such configurations can exist either as a third

Measurements of general relativistic effects in the binary pulsar PSR1913 + 16

Measurements of second- and third-order relativistic effects in the orbit of binary pulsar PSR1913 + 16 have yielded self-consistent estimates of the masses of the pulsar and its companion,

Tidal Love Numbers of Neutron Stars

For a variety of fully relativistic polytropic neutron star models we calculate the star’s tidal Love number k2. Most realistic equations of state for neutron stars can be approximated as a polytrope

Energy Emission from a Neutron Star

ALTHOUGH there are still many problems concerning the supernovae, there is little doubt that a very dense stellar core has to be left behind after the explosion (at least in some cases). During the

Confronting gravitational-wave observations with modern nuclear physics constraints

Abstract.Multi-messenger observations of neutron star (NS) mergers have the potential to revolutionize nuclear astrophysics. They will improve our understanding of nucleosynthesis, provide insights
