Releasing of nuclear energy:  

 Releasing of energy in all form of chemical or nuclear reactions is due to the releasing or expansion of space matter (ether magnetic particles) in the reactions. It is well understood that the thermo nuclear reactions in the Sun is the reason for the releasing of energy by the Sun. When nuclear particles overlap (bond) each other, they release the overlapped volume of matter to the outer world and cause to decrease some of their mass and volume. 

Since the greater density of the nuclear particles, the released matter will detonate. This detonation of the ordinary matter to space matter is the reason for the releasing of energy in nuclear reactions (see Nuclear energy).

Starlight bends when it passes through near the Sun 

There are three reasons for this phenomenon

1) The lightest form of matter –the space matter is filled everywhere in the universe. Density of space matter is greater in the near surface of the Sun (like the higher atmospheric air pressure and density on the sea level of the Earth) because of the gravitational pull that exerted on the space matter by the Sun. The density of space matter lowers with the increasing of the distance from the Sun’s surface (also same as the atmospheric air on Earth).

2) Space matter that released in the nuclear reactions creates a denser space matter medium on the surface of the Sun and it expands outward. 

3) The Sun has a denser atmosphere than ours own, made of lighter elements that extends to thousands of kilometers (altitude of the sun's atmosphere).

It is well known that, when light passes through two different density mediums, i.e. when light passes from a rare medium to denser medium or vice versa, light will be deflected or refracted. The starlight bending purely is the refraction of light by different density mediums (see What is light).

Lensing effect:

Considering a collection of stars in a galaxy, the distribution of matter is not in uniformly, i.e. in some regions, the density of the stars are more and in some regions it will be less. Because of this non- uniform distribution of matter, the net effect of the gravitational pull on the surrounding space matter and the net space matter-producing rate in the whole of the systems are also is non- uniform. This non-uniform density of space matter creates refraction of light and this refraction of light is the reason for the lensing effect.
