Using images from the Helioseismic and Magnetic Imager aboard the Solar Dynamics
Observatory, we extract the radial velocity (RV) signal arising from the suppression of …

Context. Measurements of the occultation of an exoplanet at visible wavelengths allow us to
determine the reflective properties of a planetary atmosphere. The observed occultation …

Context. Stellar variability impacts radial velocities (hereafter RVs) at various timescales and
therefore the detectability of exoplanets and the mass determination based on this …

Abstract The Closeby Habitable Exoplanet Survey (CHES) is dedicated to the astrometric
exploration for habitable-zone Earth-like planets orbiting solar-type stars in close proximity …

With dedicated exoplanet surveys underway for multiple extreme-precision radial velocity
(EPRV) instruments, the near-future prospects of RV exoplanet science are promising …

Context. Extreme precision radial-velocity spectrometers enable extreme precision in stellar
spectroscopy. Searches for low-mass exoplanets around solar-type stars are limited by …

In the past decade the study of exoplanet atmospheres at high-spectral resolution, via
transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular …

As the hunt for an Earth-like exoplanets has intensified in recent years, so has the effort to
characterize and model the stellar signals that can hide or mimic small planetary signals …

In the last few years astronomical surveys have expanded the reach of planetary science
into the realm of small and dense extrasolar worlds. These share a number of characteristics …

Context. Hot Jupiters are giant planets subject to intense stellar radiation. The physical and
chemical properties of their atmosphere make them the most amenable targets for …
