ExoClock is a very successful international program initiated and managed by Anastasia Kokori and Angelos Tsiaras at UCL to monitor transiting exoplanets in order to keep their ephemerides up-to-date (ExoClock catalogue).

We strongly believe that everyone can contribute to real research and become part of a bigger project, such as a space mission. The ExoClock team have created special tools and educational guides for any observatory that would like to support Ariel and exoplanet science. Everyone with some basic equipment, including a telescope and a CCD camera, can participate in the effort of monitoring the planets’ host stars.

Read the latest publications of the ExoClock team:

ExoClock Project: An open platform for monitoring the ephemerides of Ariel targets with contributions from the public (Kokori et al. 2021, Experimental Astronomy, in press).

Orbyts: Ephemeris Refinement of Transiting Exoplanets II (Edwards et al. 2020, Res. Notes AAS 4 109)

ORBYTS: Ephemeris Refinement of Transiting Exoplanets (Edwards et al. 2020, MNRAS, staa1245)


ExoClock is supported by the Ariel Ephemerides Working Group.
