fixed the exponential rate of change, does change numbers but not interpretation

| Feb 8, 2023 at 18:51 | comment | added | honeste_vivere | The recombination rate goes as $\sqrt{ \tfrac{ T }{ n^{2} } }$... Oh yes, I see what I missed. Just a second, I will update things accordingly | |
| Feb 8, 2023 at 16:57 | comment | added | oliver | How do you arrive at $n_e^2\sim r^{-2}$ in the denominator? If I am not completely mistaken, from $n_e\sim r^{-2}$ follows $n_e^2\sim r^{-4}$. Correct? | |
| Feb 7, 2023 at 20:00 | comment | added | honeste_vivere | I think you are missing a step. If you have $\left( \tfrac{ r^{-1.25} }{ r^{-2} } \right)^{1/2}$ = $\left( r^{+0.75} \right)^{1/2}$ = $r^{+0.375}$ | |
| Feb 7, 2023 at 15:54 | comment | added | oliver | I don't. But the density occurs to the power of two (under the square root) in the recombination time relation you have written. If a power of -2 (the density) is elevated to the power of two, a power of -4 results. Or did I misinterpret something about the formula? | |
| Feb 7, 2023 at 15:52 | comment | added | honeste_vivere | Why do you think density changes as $n \sim r^{-4}$ in the solar wind? | |
| Feb 7, 2023 at 15:44 | comment | added | oliver | I am not sure if I misunderstand some part of the argument. But shouldn't it be $t_{rec}\approx \sqrt{r^{-1.25}/r^{-4}}=\sqrt{r^{2.75}}=r^{+1.375}$, which would make the dependency much stronger than $r^{+0.375}$? | |
