PlatoSim: An end-to-end PLATO camera simulator for modelling high-precision space-based photometry
N. Jannsen, J. De Ridder, D. Seynaeve +21
PLAnetary Transits and Oscillations of stars (PLATO) is the ESA M3 space mission dedicated to detect and characterise transiting exoplanets including information from the asterosei…
YARARA V2: Reaching sub m/s precision over a decade using PCA on line-by-line RVs
M. Cretignier, X. Dumusque, S. Aigrain +1
Context. The detection of Earth-like planets with the radial-velocity (RV) method is extremely challenging today due to the presence of non-Doppler signatures such as stellar activ…
Transit Timing Variations in the three-planet system: TOI-270
Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther +69
We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered…
Revisiting K2-233 spectroscopic time-series with multidimensional Gaussian Processes
Oscar Barragán, Edward Gillen, Suzanne Aigrain +7
Detecting planetary signatures in radial velocity time-series of young stars is challenging due to their inherently strong stellar activity. However, it is possible to learn inform…
Discovering planets with PLATO: Comparison of algorithms for stellar activity filtering
G. Canocchi, L. Malavolta, I. Pagano +7
Context. To date, stellar activity is one of the main limitations in detecting small exoplanets via transit photometry. Since this activity is enhanced in young stars, traditional…
