A team of researchers at the IIST, Thiruvananthapuram, recently discovered radio emission with a special property known as circular polarisation near a massive young protostar that is still forming about 4,500 light-years from Earth.
About Protostar:
A protostar is an early stage in the star formation
It is a large mass of gas and dust formed as a result of the contraction of a giant molecular cloud in the interstellar medium.
As the cloud collapses,gravitational energy is converted into heat, warming the still-forming protostar.
It may last from 100,000 to 10 million years, depending on the mass of the star.
It begins with an increase in density in the molecular cloud core and ends with the formation of a pre-main-sequence star.
Pre-main-sequence stars of similar mass to the Sun are known as T-Tauri stars.
Once hydrogen fusion ignites in the core of a star, it begins producing energy and becomes a main sequence star.
Protostars are usually surrounded by dust, which blocks the light that they emit, so they are difficult to observe in the visible spectrum.
