Most people know that planets and stars are quite different. They may be surprised by the fact that there some cases when even scientist is puzzle by a type of celestial object which is known as a brown dwarf. The object can be classified either a large planet or a small star.
Researchers from the Heidelberg University discovered new evidence which suggests that brown dwarfs tend to form like planets. While planets and stars tend to form in a similar manner the circumstances have to be different.
For example, a cloud of dust and gas can transform into a star when a large amount of material accumulates, and intense heat and pressure will start a nuclear fusion reaction, which leads to the appearance of a core. Planets will form from the material which remains after a star forms. The main difference is represented by the fact that the matter will not transform into a mass which can ignite into another core.
The new study discovers more information about brown dwarfs
Brown stars are fascinating because they appear to be situated in the middle. They are big enough to allow nuclear fusion within their cores, and it may last for a while, but they are unable to sustain the process and release light. Some researchers believe that their mass is ten times bigger than that of Jupiter. If it is smaller than this, it can be deemed a regular planet.
Their nature is quite puzzling since an obvious question appears: are they large planets or incomplete stars? Some of them appear to feature traits present across both types of celestial objects. Several brown dwarfs travel around space as rogue planets while others tend to orbit around stars. In some cases, planets will orbit around brown dwarfs.
The study observed two brown dwarfs which followed a strange orbiting pattern. One of the planets needed 530 days to complete an orbit while the other need 3,185, reinforcing the line of thought which suggests that they form like planets. The results were published in a peer-reviewed journal.
