Transit detection of the long-period volatile-rich super-Earth Lupi d with
Laetitia Delrez, David Ehrenreich, Yann Alibert +75
Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of planetary formation and evolution. The wealth of photons from the host star gives detailed…
CHEOPS Precision Phase Curve of the Super-Earth 55 Cnc e
B. M. Morris, L. Delrez, A. Brandeker +79
55 Cnc e is a transiting super-Earth (radius and mass ) orbiting a G8V host star on a 17-hour orbit. Spitzer observations of the planet's phase…
Some detection tests for low complexity data models and unknown background distribution
D. Mary, S. Bourguignon, E. Roquain +2
We consider several detection situations where, under the alternative hypothesis, the signal admits a low complexity model and, under both the null and the alternative hypotheses,…
Mitigating flicker noise in high-precision photometry. I -- Characterization of the noise structure, impact on the inferred transit parameters, and predictions for CHEOPS observations
S. Sulis, M. Lendl, S. Hofmeister +4
In photometry, the short-timescale stellar variability ("flicker"), such as that caused by granulation and oscillations, can reach amplitudes comparable to the transit depth of Ear…
3D magneto-hydrodynamical simulations of stellar convective noise for improved exoplanet detection. I. Case of regularly sampled radial velocity observations
S. Sulis, D. Mary, L. Bigot
Convective motions at the stellar surface generate a stochastic colored noise source in the radial velocity (RV) data. This noise impedes the detection of small exoplanets. Moreove…
Multi-season optical modulation phased with the orbit of the super-Earth 55 Cnc e
S. Sulis, D. Dragomir, M. Lendl +13
Context. 55 Cnc e is a transiting super-Earth orbiting a solar-like star with an orbital period of 17.7 hours. In 2011, using the MOST space telescope, a quasi-sinusoidal modulatio…
