  • Summary

    Exoplanets are planets orbiting stars other than our sun. While some have now been detected (or confirmed) by direct imaging, most exoplanet detections have been made via two other more-indirect techniques, known as the radial-velocity and transit methods. These methods have analogs in the study of stellar binary systems, as outlined in Chapter 10. We explore the population of known exoplanets and how we must compensate for observational biases inherent in each of these techniques.

  • This resource was developed to help bring this exciting area of research into the classroom. It consists of two practical activities appropriate for the K12 curriculum.

    Each of the activities is standalone, takes around 60 minutes to complete and can be used either during lessons or as part of a science club. Each offers plenty of opportunity for extension work and includes a taking it further section to allow students to build on what they have learnt through independent research. The activities can be used individually, or in combination. We have already implemented them during the astrophysics summer courses we offer to school students at the National Observatory of Athens, with great success.
