OTS44 is a planetary-mass object like brown dwarf located at 550 light-years from Earth in Chameleon constellation. Recently a group of astronomers led by the University of Valparaiso investigates the formation of the disk of dust particle around it.
According to study, this formation around this planet-like OTS44 is very similar to the early stage of our solar formation. Though, the comprehensive study suggests that the formation contravenes the conventional theory about the formation of planets and stars. Regarding this a research paper published in The Astrophysical Journal Letters.
As per the study, this Planetary-mass object has no host star near around it that makes it as a free-floating stellar object. OTS44 was discovered in 1998 with the help of infrared vision of Spitzer Space Telescope. According to data, the mass estimates for the dust contained in the disk, which places OTS44 in a row with stars and brown dwarfs.
Other associates from the Max Planck Institute for Astronomy informed OTS44 is still growing by drawing matter from its disk onto itself. They claimed that the property has quite a similarity between the object and a young star.
According to data from The University of Valparaiso, the formation of OTS44 has the similar way with the formation of stars and brown dwarfs. However, OTS44 has too much low mass and according to the theory, it should not be possible to form a star from an extremely low-mass object.
As per research lead Amelia Bayo, the strange formation of the OTS44 has violated the conventional theory of the formation of massive objects. Regarding this, she assumed that if Jupiter was produced from a huge amount of gas and stone bands without the solar system then the matter would have been weird. From this, she actually pointed that, as per standard theory the formation of Jupiter will very complicate to explain without the Solar system.
Apart from this, researchers find another question arise about disk which is around the similar size of Jupiter. The mass of the disk is equivalent to the Earth. The strength of the radiation received from the dust at millimetric wavelength using ALMA interferometer. According to that data, the signal detects the presence of large, millimeter-sized dust grains in the disk. However, the growing nature of the dust suggests the possibility of forming a mini-moon around the OTS44 in future. This means this object resemble both planets as well as star.
