Context

  • Recently, in a significant astronomical breakthrough, scientists from the Indian Institute of Space Science and Technology (IIST), Thiruvananthapuram, have detected circularly polarised radio emissions near the massive young protostar IRAS 18162-2048.
    This marks the first direct evidence of strong magnetic fields in the immediate environment of such a protostar.

About IRAS 18162-2048

  • A massive protostar located about 4,500 light years away in the Milky Way. It is one of the most studied massive protostars due to its unique energetic features.
  • The protostar is known for powering HH80-81, one of the largest and brightest bipolar jets in the galaxy-ejecting high-speed matter in opposite directions.
  • These Herbig-Haro (HH) jets are crucial markers of early star formation. 
  • New Discovery: While previous studies had mapped magnetic fields along the jet, the latest detection marks the first direct evidence of magnetic activity near the core of the protostar.
  • This strongly suggests that magnetic fields play a key role in launching and regulating such massive outflows.
  • Scientific Impact: The discovery provides new insights into high-mass star formation, a less understood process compared to low-mass star formation. It supports the theory that magnetic fields are essential in shaping early stellar evolution.

About Protostar

  • An early stage in the process of star formation, preceding the main sequence phase. 
  • It forms from the collapse of a giant molecular cloud in the interstellar medium, composed mainly of gas and dust.
  • Becomes a main sequence star once hydrogen fusion begins in its core. 
  • Typically obscured by surrounding dust, making them difficult to detect in visible light.
