Oxygen abundance in coronal streamers during solar minimum

Giordano, S.; Antonucci, E.; Marocchi, D.

We present a study of the oxygen abundance relative to hydrogen in the equatorial streamer belt of the solar corona during the recent period of activity minimum. The oxygen abundance is derived from the spectroscopic observations of the outer corona performed during 1996 with the Ultraviolet Coronagraph Spectrometer (SOHO) in the ultra-violet regi…
