What is Exoplanet Detection: The Radial Velocity Method?

Exoplanet Detection: The Radial Velocity Method

Exoplanet Detection: The Radial Velocity Method is a really cool Java-based app that helps you simulate how we find exoplanets. It uses something called the radial velocity method along with the Doppler effect to do this. Basically, in this simulation, the exoplanet goes around a star that's about the size of our sun, moving in a circular path as explained by Kepler's third law.

Understanding Radial Velocity

So, what's up with radial velocity? Well, it's all about figuring out how fast the star is moving based on the speed of its orbiting exoplanet. This speed gives us clues about the Doppler shift of the Fraunhofer lines seen in the star's spectrum.

How Does It Work?

The app takes you through each step. First, you set up your star and exoplanet parameters. Once that's done, it runs calculations to show how the light from that star changes as the planet moves around it.

Why Is This Important?

This method is super important for astronomers because it helps us discover new planets outside our solar system! By studying these shifts in light, scientists can determine if there are planets we didn't know about before.
