Our first task was to estimate the planet's radius and mid-transit time by creating a light curve based on this data in the Allesfitter program. The program evaluated our curve and determined how accurate we were and we obtained the correct value to compare with our result. We saw that our estimate of the transit depth had 2,6% deflection from Allesfitter, that was not bad for beginners. From the Allesfitter program we also received more data - the mass of the planet, temperature and time period… (see attached pictures). Radius A light curve shows percentage values of light coming from the star in time. The difference between the smallest measured value and the maximum is called transit depth. It’s approximately the ratio of the area of the planet's disc and the area of the star's disc. With this ratio, we determined the planet radius (see calculation below) Volume, density The planet's radius is ca. 2.45 larger than of our planet Earth, which means its volume is appro
TOI-560 c was discovered in 2021 by the TESS (Transiting Exoplanet Survey Satellite). Two years later, ESA’s satellite Cheops came to explore the planet. The Characterising Exoplanet Satellite, in short Cheops, was launched in 2019 and since then it has been studying exoplanets. It characterizes already discovered exoplanets by transit photometry even more precisely than by their discovery. This method records intensity of the light coming illuminated by a star. When a planet transits a star, it is recorded as a weakening of the light. By analyzing this data scientists (and now we) are able to calculate a lot of parameters about the studied planet. TOI-560 c has also the positive that it’s situated in our plane of observation, so we get more accurate data from the observation.
