Answer:

Star A is a neutron star and star B is a Red giant.

Explanation:

A neutron temperature are extremely hot objects having very high density and appear white in color. They emit large amount of x-rays. A white dwarf is relatively cooler than a neutron star. Black dwarfs emit no light. A red giant star is a cool star. Thus, star A must be a neutron star.

Star B is red in color and has low temperature and extremely bright. Therefore, it must be a red giant star. A blackhole is not visible, a red dwarf is not bright enough to be visible where as a supernova is an event in which a massive star explodes within a short interval of time.

Before the signal can travel on, however, it passes through another nearby structure called the thalamic reticular nucleus (TRN), which evaluates whether or not it should be passed on.
