Modelling stellar activity with Gaussian process regression networks
J. D. Camacho, J. P. Faria, P. T. P. Viana
Stellar photospheric activity is known to limit the detection and characterisation of extra-solar planets. In particular, the study of Earth-like planets around Sun-like stars requ…
The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…
SWEET-Cat 2.0: The Cat just got SWEETer; Higher quality spectra and precise parallaxes from GAIA eDR3
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +13
Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number o…
Warm terrestrial planet with half the mass of Venus transiting a nearby star
Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…
The SOPHIE search for northern extrasolar planets. XVIII: Six new cold Jupiters, including one of the most eccentric exoplanet orbits
O. D. S. Demangeon, S. Dalal, G. Hébrard +28
Context. Due to their low transit probability, the long-period planets are, as a population, only partially probed by transit surveys. Radial velocity surveys thus have a key role…
Decoding the radial velocity variations of HD41248 with ESPRESSO
J. P. Faria, V. Adibekyan, E. M. Amazo-Gómez +13
Twenty-four years after the discoveries of the first exoplanets, the radial-velocity (RV) method is still one of the most productive techniques to detect and confirm exoplanets. Bu…
