Lifetime: February 1983 - November 1985

Country (primary): Japan

Primary Science

The primary science objective of the Tenma mission was to provide high-resolution spectroscopy of the X-ray emission from stars and to observe gamma-ray bursts.

Science Highlights

  • Discovered hot plasma located along the Galactic plane
  • Discovered the iron absorption line in the energy spectra of X-ray bursts, which was redshifted in the strong gravitational field of the neutron star
  • Discovered that cold iron (in other words, neutral iron, not ionized) is responsible for the iron emission line in X-ray pulsars
