Scientific paper

The appearance of SN 1987A in the Large Magellanic Cloud (LMC) considerably improved the possibility of detecting the presence of a hot (T ⪆ 106K) interstellar gas in either the halo of our own Galaxy or that of the LMC. Verification of its existence could take the form of a detection, in absorption, of the coronal forbidden line [Fe X] at 6374.51 Å. The authors present the results from their investigation of the [Fe X] spectral region toward SN 1987A. They report the detection of significant LMC [Fe X] absorption at a velocity corresponding to the 30 Doradus II region. An absorption feature at the predicted Galactic [Fe X] absorption wavelength is detected but cannot be positively identified with [Fe X] in the Galactic halo.
