Dark matter of the sun

Evidence of the existence of dark matter comes from large objects, ranging from the galactic caliber to the structure of the universe itself. But a manuscript published in Science indicates that we can look at something smaller and closer to the Sun, if we will begin to find out what the dark matter looks like. Because dark matter interacts through gravity, the Sun has the greatest concentration of gravity around us, and it argues that supplementary material should affect the production of neutrinos in detectable ways.

The text is a Brevia (short report) and the text is not even a full page, but it extracts a lot of information into the short page. The authors point out that the gravity of the Sun will capture dark matter as it travels through the Milky Way and with these dark matter particles in the Sun, at least causing weak and sparse collisions with ordinary matter. The particles will eventually accumulate in the core of the Sun which will then affect the fusion reaction that occurs.

According to the current solar mapping, different reactions occur at different depths, and this will lead to the unequal distribution of neutrinos produced by these reactions. Dark matter will change the locations of this reaction and cause detectable differences in the flow of neutrinos coming out of the Sun. Currently we do not yet have the hardware to detect these differences, but the researchers say they will soon have a neutrino observatory.

It should be noted that the mapping of the dark matter they use contains some assumptions beyond the interaction with ordinary matter, such as the mass of the particles themselves and their ability to eliminate each other in collisions. But the researchers showed how changing these assumptions could produce significantly different results. This means that although the experiments to be performed do not provide convincing evidence of dark matter, at least they can reveal some mappings like what exactly the dark matter particles are.
