the temperature curve beyond the photosphere must be wrong. why it goes high and high when it is far away from the center?

I wonder about it, too. Can't someone explain? 212.87.13.66 (talk) 19:54, 26 March 2014 (UTC)[reply]

It's a mysterious but well-known phenomenon. Eric Kvaalen (talk) 09:45, 3 August 2017 (UTC)[reply]

Eric Kvaalen is right. It has been recorded by many past solar orbiters that the temperature increases outside the photosphere, gaining up to one million Kelvin in the solar corona. This phenomenon has been linked to CMEs, flares and other observed facts in the solar corona. Hints from the magnetohydrodynamics suggest that there is a link between these aspects and the solar magnetic field, but no autoconsistent physics has been found to explain all these events, yet. 151.18.163.174 (talk) 14:14, 20 April 2022 (UTC)[reply]

Extra lines in the graph[edit]

The vertical lines at the lower left show the temperatures of:

(1) melting gold, 1337 K
(2) melting iron, 1808 K
(3) boiling silver, 2485 K
(4) an acetylene welding flame
(5) an iron welding arc.

The densities or density ranges shown at the top are:

(A) density of our atmosphere at an altitude of 50 km
(B) Earth atmosphere at 90 km
(C, D, E) ranges of vacuum densities achieved by laboratory vacuum pumps: (C) mechanical vacuum pump, (D) diffusion pump, and (E) ion pump.
