Predominant Emission from Neutron Stars
A neutron star is an astronomical object resulting from the collapse of a supernova, characterized by its incredibly high density. The core of a neutron star is primarily composed of neutrons, and due to their stability, they create a strong gravitational field that leads to interesting nuclear interactions. Consider a neutron star with a radius of about 10 km and a mass approximately 1.4 times that of the Sun (about 2.8 × 1030 kg). If the neutron star emits a beam of radiation that is observed from Earth, the emission mechanism can be understood within the context of quantum tunneling and nuclear decay processes. Assuming the neutron star's surface has a temperature of about 1 million Kelvin, which of the following emissions would be the most predominant in this scenario?
