A symmetrically pulsed jet of gas from an invisible protostar in Orion
Article Abstract:
Infrared observations have revealed an unusual interstellar jet linked to a very young star, or protostar, close to the Horsehead nebula in Orion. The young star itself is invisible. A study of the jet reveals a number of paired 'knots' and shocks can be seen at the bow edges. The jet's extreme symmetry suggests that it could have formed from chaotic or recurrent instabilities in the protostar's accretion disk.

Reflected infrared spectrum of a massive protostar in Orion
Article Abstract:
Astronomy research using infrared radiation has provided more data to ascertain the nature of the star-forming region Orion-KL. Evidence suggeststhat the star measures over 300 solar radii in size. The star accretes an estimated 5-15 times ten (super -3) every year. The characteristics of the star's luminous source are assessed using K-band spectra analysis.
