Orbital Period Refinement of CoRoT Planets with TESS Observations
Peter Klagyivik, Hans J. Deeg, Szilard Csizmadia +2
CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first…
The power of wavelets in analysis of transit and phase curves in presence of stellar variability and instrumental noise I. Method and validation
Sz. Csizmadia, A. M. S. Smith, J. Cabrera +3
Stellar photometric variability and instrumental effects, like cosmic ray hits, data discontinuities, data leaks, instrument aging etc. cause difficulties in the characterization o…
Constraining the radius and atmospheric properties of directly imaged exoplanets through multi-phase observations
Óscar Carrión-González, Antonio García Muñoz, Nuno C. Santos +3
The theory of remote sensing shows that observing a planet at multiple phase angles () is a powerful strategy to characterize its atmosphere. Here, we analyse how the informatio…
The changing face of AU Mic b: stellar spots, spin-orbit commensurability, and Transit Timing Variations as seen by CHEOPS and TESS
Gy. M. Szabó, D. Gandolfi, A. Brandeker +78
AU Mic is a young planetary system with a resolved debris disc showing signs of planet formation and two transiting warm Neptunes near mean-motion resonances. Here we analyse three…
Exploiting timing capabilities of the CHEOPS mission with warm-Jupiter planets
Borsato L, Piotto G, Gandolfi D +75
We present 17 transit light curves of seven known warm-Jupiters observed with the CHaracterising ExOPlanet Satellite (CHEOPS). The light curves have been collected as part of the C…
The EBLM project -- VIII. First results for M-dwarf mass, radius and effective temperature measurements using CHEOPS light curves
M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +93
The accuracy of theoretical mass, radius and effective temperature values for M-dwarf stars is an active topic of debate. Differences between observed and theoretical values have r…
