Separating planetary reflex Doppler shifts from stellar variability in the wavelength domain
A. Collier Cameron, E. B. Ford, S. Shahaf +28
Stellar magnetic activity produces time-varying distortions in the photospheric line profiles of solar-type stars. These lead to systematic errors in high-precision radial-velocity…
Identifying Exoplanets with Deep Learning. IV. Removing Stellar Activity Signals from Radial Velocity Measurements Using Neural Networks
Zoe L. de Beurs, Andrew Vanderburg, Christopher J. Shallue +24
Exoplanet detection with precise radial velocity (RV) observations is currently limited by spurious RV signals introduced by stellar activity. We show that machine learning techniq…
K2-111: an old system with two planets in near-resonance
A. Mortier, M. R. Zapatero Osorio, L. Malavolta +64
This paper reports on the detailed characterisation of the K2-111 planetary system with K2, WASP, and ASAS-SN photometry as well as high-resolution spectroscopic data from HARPS-N…
Three Years of HARPS-N High-Resolution Spectroscopy and Precise Radial Velocity Data for the Sun
X. Dumusque, M. Cretignier, D. Sosnowska +35
The solar telescope connected to HARPS-N has been observing the Sun since the summer of 2015. Such high-cadence, long-baseline data set is crucial for understanding spurious radial…
TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs
Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85
Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…
TESS Hunt for Young and Maturing Exoplanets (THYME) III: a two-planet system in the 400 Myr Ursa Major Group
Andrew W. Mann, Marshall C. Johnson, Andrew Vanderburg +51
Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits, and structures are shaped by their environment. Young planets (1 Gyr) offer an oppo…
