Do neutron stars reflect light?
Neutron stars do not reflect light in the classical sense. Due to their incredibly strong gravitational pull, not even light can escape once it gets too close to the surface of a neutron star. This phenomenon is known as gravitational redshift.
In fact, the gravitational field of a neutron star is so strong that it warps the surrounding space-time, causing any radiation emitted by the star to be severely distorted. This distortion includes a strong gravitational redshift, which shifts the emission spectrum towards longer wavelengths, making it difficult to observe the star's original radiation.
However, it is possible to observe neutron stars indirectly through the effects they have on their surroundings. For example, neutron stars can heat up surrounding material, causing it to emit X-rays or other forms of radiation that can be detected from Earth.
