How to Make a Light Curve for an Exoplanet Transit

Discipline: 
Education

This guide describes how to create a light curve for an exoplanet transit by measuring the brightness of the target star and a comparison star in several frames. You can do this with sample data available from the Faulkes Telescopes, or with data from your own observation if you have an account. After doing this activity you should be able to:

Photometry to Find the Color of a Star

Discipline: 
Education

Photometry is the measurement of the intensity or brightness of an astronomical object, such as a star or galaxy by adding up all of the light from the object. For example, a star looks like a point of light when you look at it just with your eyes but the Earth’s atmosphere smears it out into something that looks like a round blob when you use a telescope to look at it. In order to measure the total light coming from the star, we must add up all of the light from the smeared out star. Photometry is generally used to generate light curves of objects such as variable stars and
