The discovery was made by radio observations with the Karl G. Jansky Very Large Array (VLA) from the National Science Foundation.

The presence of magnetic force in a body with a brown dwarf and interplanetary mass can give information about the magnetic processes on both the planet and the star.

The brown dwarf is too large to be accepted as a planet, but too small to be a star. Nuclear reaction does not occur in nuclei. They were theoretically introduced in the 1960s and were first observed in 1995. At first, they thought that they did not spread radio waves, but in 2001 they discovered a brown dwarf with a powerful magnetic field emitting radio waves with the help of VLA.

In subsequent observations, it was determined that some brown dwarfs had strong auroral (pole lights) as seen in the gas giants of the Solar System. The polar lights observed in the earth are the interaction of the solar wind with the magnetic field. However, there is no star in the brown dwarf that will create such a wind. How the polar lights are formed in the brown dwarf is an unresolved question. Nevertheless, the magnetic interaction between Jupiter and the conforming Io can give the answer to this question. So, if there is a planet near the brown dwarf, polarized lights can form through magnetic interaction.

The last observed SIMP J01365663 + 0933473 odd object has a magnetic field greater than 200 times that of Jupiter.

The object is one of five objects discovered for the first time in the brown dwarf research of magnetic field in 2016. When the masses of the brown dwarf were discovered to be very difficult to measure, they were thought to be old and big brown dwarf.

In the past year, a group of researchers determined that it was part of a celestial young star community. The young body is about 1.22 in Jupiter and 12.7 in mass. He is 200 million years old and 20 light years away from Earth. The surface temperature is 825 degrees centigrade. In terms of comparison, it is worth noting that the surface temperature of the Sun is 5500 degrees centigrade.

The differences between a gas giant and a brown dwarf are a matter of debate among astronomers. Nonetheless, astronomers generally have around 13 Jupiter masses and define objects that are ‘on the deuterium burning boundary’ as brown dwarfs.

Simultaneously viewing the body again in 2016 with radio data, Caltech revealed that the magnetic field is stronger than the first measurements.

SIMP J01365663 + 0933473 is a body near the deuterium burning limit. Using VLA and radio observations, the first measurements of the magnetic field of a planetary mass beyond the Solar system were made.
