Discovering the Solar Corona Luminosity Curve: Explained and Explored

AI Thread Summary
The discussion centers on determining the solar corona luminosity curve in relation to distance, noting that the corona can be observed up to 4 solar radii. The curve is described as approximately exponential, but the exact equation is sought. A reference to a figure from a specific document suggests a temperature range of about 1,500,000 K for the corona, indicating that the highest luminosity value could be ten times the lowest. The relationship between temperature and luminosity is highlighted using the equation L=4π(R^2)σ(T^4), leading to a conclusion that the difference in luminosity could be calculated by multiplying the lowest values by 10^4. Clarification on the accuracy of this approach is requested.

I've been trying to find out what's the curve for the solar corona luminosity vs distance like.
I know that the corona can be practically observed up to 4 solar radii. I also found out that the curve is more or less exponential but I need the actuall equation of the curve.

Can anyone help me?

Judging by that figure I assume that the difference in temperature (from the lowest to the highest value) for the corona is about 1 500 000 K (more or less), which means that the lowest value must be multiplied by 10 to reach the highest.
So, based on the equation that relates temperature and luminosity [L=4π(R^2)σ(T^4)] I guess the difference in luminosity (from the lowest to the highest value) can be found if we multiply the lowest values by 10^4.

Am I right?
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
