What is a brown dwarf?

brown dwarf is the body on the edge of a very large planet or very small stars. Brown dwarves range from 13 to about 90 Jupiter materials. The International Astronomical Union lists the boundary between large planets and small brown dwarves on 13 masses of Jupiter, because this is the weight threshold necessary for deutria fusion.

Deutrium is an isotope of hydrogen that includes a neutron in the core, rather than just a proton as a common hydrogen, and is the simplest type of atom to the fuse. Since Deutrium is compared to conventional hydrogen - for example, for Jupiter, for example for the creation of a real star, and so brown dwarves are often called "unsuccessful stars", for example, not enough - not enough.

At approximately 0.075 solar masses, or 90 jupiter materials, brown dwarves will become able to combine normal hydrogen - albeit much slower than the main sequential stars like our Sun, making them red dwarves, stars with about 1/10 000 solar luminaires. AngerDwarfs generally show very low or no luminosity, generating heat primarily through radioactive elements contained in them, as well as temperature due to compression. Since brown dwarves are very matte, it is difficult to observe them from a distance and only a few hundred are known. The first brown dwarf was confirmed in 1995. The alternative name that was designed for brown dwarves was "Subrar".

An interesting feature of brown dwarfs is that they all have almost the same radius - about the properties of Jupiter - between them only 10% to 15%, although their mass is up to 90 times higher than that of Jupiter. In the low weight range, the volume of the brown dwarf is determined by the Columbus pressure, which also determines the volume of planets and other low matter objects. In a higher mass scale range, the volume is determined by the pressure of electron degeneration - ie atoms are printed as close as possible to each other withoutcollapse of electron shells.

The physics of these two arrangements is that as the density increases, the radius is roughly maintained. When another mass is added around the upper limits of brown dwarf masses, the volume begins to increase again and produce large celestial bodies with a radius closer to our sun.
