Steg 5 - Sammansättning
Step 5 – Composition In our Solar System, planets are usually divided into two categories: rocky and gaseous. However, exoplanets can be very different from the neighbouring planets we are used to. The mass, M, of an exoplanet cannot be determined from the transit method, but other methods like radial velocity can. When both the […]
Steg 4 - Temperatur och beboelighet
Step 4 – Temperature and Habitability To this day, Earth is the only place in the universe that is known to host life. It is also unknown if life could develop and exist in conditions very dissimilar to the ones that exist on our planet. When examining exoplanets and defining the possible conditions for habitability, […]
Steg 3 - Omloppstid och avstånd
Step 3 – Orbital Period and Distance The orbital period, T, of a planet is the time it takes the planet to complete one full orbit around its star. If multiple transits of the same exoplanet are observed, then the time interval between consecutive transits – detected dips in the light curve – is a […]
Steg 2 - Exoplanetens storlek
Step 2 – The Size of the Exoplanet The depth of the exoplanet transit is equivalent to the ratio of the area of the planet’s disc and the area of the star’s disc. By measuring the transit’s depth from the transit light curve and knowing the stellar radius (Rs) you can determine the exoplanet’s radius […]
Steg 1 - Få tillgång till uppgifterna
Steg 1 - Få tillgång till data För att slutföra din detektivs uppdrag måste du välja ditt mål och få tillgång till data från Cheops-satelliten. Vi föreslår att du börjar ditt uppdrag med KELT-3b. Astronomer använder specifika programvaruverktyg för att analysera data och anpassa matematiska modeller. Få tillgång till data med hjälp av ett av de två alternativen nedan. [...]
Hacka en exoplanet Guide för pedagoger
Hack an Exoplanet Guide for Educators Brief description: In this activity, students will characterise two exoplanets by analysing data acquired by ESA’s Cheops satellite. Students will work as real scientists and fit a model to the data to retrieve the best fit parameters. The activity can be completed using a guided format or in a […]
