The first cheops science paper and CHEOPS mission Paper are accepted for publication

28 Sept 2020: The first science paper based on CHEOPS observations of WASP 189b (Lendl et al. arXiv:2009.13403) was accepted for publication in Astronomy and Astrophysics. The web story on the work can be found at this link.

Also accepted for publication a few days previously, was the mission paper by Benz et al. (arX:2009.11633, to appear in Experimental Astronomy). This provides a comprehensive overview of the science of CHEOPS, as well as an overview of each of the different elements of this first S-(small) class science mission in ESA's Cosmic Vision Programme.

Note: a list of selected CHOEPS publications can be found at this link, which includes a link to the ADS library which contains all publications published since launch (December 2019).

Cheops observes its first exoplanets and is ready for science

16 April 2020: Cheops, ESA’s new exoplanet mission, has successfully completed its almost three months of in-orbit commissioning, exceeding expectations for its performance. The mission passed its in-orbit commissioining review on the 25 March 2020, making the handover of responsiblity for operations to the CHEOPS Mission Consortium, led by the University of Bern. The satellite, which will commence routine science operations by the end of April, has already obtained promising observations of known exoplanet-hosting stars, with many exciting discoveries to come.

A perfect blur; First image From CHEOPS

7 February 2020: CHEOPS acquired the first image of its initial target, a key milestone in the in-orbit commissioning phase. The intentionally blurry image is a product of the specially designed telescope optics, which are deliberately defocused to maximise the precision of Cheops’ measurements and enable its unprecedented study of exoplanets, or planets in other solar systems.
