The authors of the study stated that these three fastest brown dwarfs will approach the
These three dwarfs have about the same diameter as Jupiter, but are 40 to 70 times more massive.The fastest rotates on its axis once an hour, compared to JupiterIt rotates once every 10 hours.Based on their size, this means that the largest brown dwarf is spinning at a speed of 100 km per second, or 360,000 km.km per hour.
As brown dwarfs cool with age, the temperature difference allows forsuggest that these brown dwarfs are different numbers of years before a rotating objectAs it breaks apart, it usually becomes flatter as it deforms under pressure.
Given that brown dwarfs tend to accelerate with age, scientists are stillDon't know if they often exceed their rotational speed limit and break apart?For example, other stars have natural braking mechanisms that protect them fromIt is not yet clear whether similar mechanisms exist in brown dwarfs.
Maximum rotation speed of any objectis determined not only by its total mass, but also by how this mass is distributed. Therefore, it is important to understand the internal structure of a brown dwarf: the material inside it is likely to shift and deform in such a way that it can change the speed of rotation of the object. Like gaseous planets such as Jupiter and Saturn, brown dwarfs are composed primarily of hydrogen and helium.
Physicists use observations, laboratory dataand mathematics to create models of how brown dwarfs should look inside and how they will behave in extreme conditions. But current models show that the brown dwarf's maximum rotational speed should be about 50-80% faster than the hourly rotation period described in the new study.
Scientists continue their work on this topic.
