Photons and solar wind/plasma interaction?

In summary, the conversation is discussing whether the sun's photons can accelerate the plasma/solar wind away from the sun or if there is no interaction between them. The Wikipedia page on radiation pressure is referenced, which explains that while radiation pressure from the sun can contribute to the acceleration of the solar wind, it is not enough to fully explain its high velocities. This remains a mystery.

What an astute observation! - It's interesting, that the observed velocities of the solar wind cannot be explained by purely kinetic energy based on the temperature of the sun's corona. Radiation pressure from the Sun's blackbody radiation will help accelerate the solar wind, but the effect is still not large enough to account for the wind's high velocities, so it's still an open mystery...
 

1. What are photons?

Photons are tiny packets of energy that make up electromagnetic radiation, including visible light. They have no mass and travel at the speed of light.

2. How do photons interact with solar wind?

When photons from the sun reach the Earth's atmosphere, they can be absorbed, scattered, or reflected by particles in the solar wind. This interaction can create phenomena such as the aurora borealis.

3. What is the solar wind?

The solar wind is a stream of charged particles, mainly protons and electrons, that are constantly emitted from the sun. It travels at high speeds and can interact with the Earth's magnetic field.

4. How does the solar wind affect the Earth's atmosphere?

The solar wind can cause disturbances in the Earth's magnetic field, leading to auroras and other geomagnetic storms. It can also affect satellite communications and power grids on Earth.

5. What is plasma and how does it relate to solar wind?

Plasma is a state of matter that is created when gas is heated to extremely high temperatures, causing the atoms to break apart into charged particles. The solar wind is made up of plasma, and its interactions with the Earth's magnetic field can create complex and dynamic phenomena in our atmosphere.
