Question
The IRIS and TRACE probes took many photos of the “loops” formed by flux tubes in this region. For 10 points each:
[10m] Name this region whose magnetic field is being measured by the Parker Probe to test theories of its namesake“heating problem.” This region’s outer boundary at the Alfvén surface is where the solar wind begins.
ANSWER: solar corona [prompt on the Sun’s atmosphere]
[10e] Eugene Parker attributed the corona’s high temperature to “nano-” versions of these events. Coronal mass ejections often accompany these bursts of radiation that occur in the Sun’s active regions.
ANSWER: solar flares [accept nanoflares]
[10h] The corona heating problem was first discovered from the spectra of highly-ionized atoms of this element. In stellar nucleosynthesis, nuclei heavier than this element are produced by the r and s-processes.
ANSWER: iron [or Fe]
