Axion search - Hot plasma on the quiet sun (movie)
|
While searching for the X-ray signature of Axions
(see
RHESSI Science Nugget for details) XRT has taken a set of
8x8 binned images with long exposures through our Medium Beryllium
filter. This filter is mainly sensitive to thermal plasma around 10 MK.
The images
seen in the movie show hot plasma in small x-ray bright points and
in large scale unresolved structures above the quiet sun.
Some of the large scale stucture connects distant regions of strong
magnetic field, some appears to be connecting quiet sun near the pole
with lower latitude. The heating of this unresolved plasma is not understood.
The small white spots are from
high energy electrons hitting the CCD as Hinode passes through the earth's
radiation belts. We see more of these in long, binned exposures.
