TL;DR: The PLATO 2.0 instrument consists of 34 small aperture telescopes (32 with 25 sec readout cadence and 2 with 2.5 sec candence) providing a wide field-of-view (2232 deg2) and a large photometric magnitude range (4-16 mag) as discussed by the authors.

TW Hydrae: evidence of stellar spots instead of a Hot Jupiter
Nuria Huélamo,P. Figueira,X. Bonfils,Nuno C. Santos,Francesco Pepe,Michaël Gillon,Ryan Ribeiro de Azevedo,Travis Barman,Matilde Fernández,E. Di Folco,Eike W. Guenther,C. Lovis,Claudio Melo,D. Queloz,Stéphane Udry +14 more
TL;DR: In this article, the authors used a hot spot model to fit the RV variations of TW Hya using a cool spot model and obtained new high-resolution optical and infrared spectra, together with optical photometry, to detect the signal of the planet companion.

TL;DR: In this article, the authors fitted the RV variations of TW Hydrae using a cool spot model and showed that a cold spot covering 7% of the stellar surface and located at a latitude of 54 deg can reproduce the reported RV variations.
