We developed a dedicated statistical test for a massive detection of spot- and facula-crossing anomalies in multiple exoplanetary transit lightcurves, based on the frequentist -…
ExoClock Project: An open platform for monitoring the ephemerides of Ariel targets with contributions from the public
Anastasia Kokori, Angelos Tsiaras, Billy Edwards +46
The Ariel mission will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres. For the mission to be as efficient as possible, a good knowledge…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
