Planet Earth in reflected and polarized light -- III. Modeling and analysis of a decade-long catalog of Earthshine observations

Giulia Roccetti, Michael F. Sterzik, Claudia Emde +3

Earthshine observations offer a unique opportunity to study Earth as an exoplanet seen from the Moon. As the Sun-Earth-Moon geometry changes, Earth can be observed as a spatially u…

Planet Earth in reflected and polarized light: II. Refining contrast estimates for rocky exoplanets with ELT and HWO

Giulia Roccetti, Michael F. Sterzik, Julia V. Seidel +3

The characterization of nearby rocky exoplanets will become feasible with the next generation of telescopes, such as the Extremely Large Telescope (ELT) and the mission concept Hab…

Planet Earth in reflected and polarized light I. 3D radiative transfer simulations of realistic surface-atmosphere systems

Giulia Roccetti, Claudia Emde, Michael F. Sterzik +3

Future telescopes will characterize rocky exoplanets in reflected light, revealing their albedo, which depends on surface, cloud, and atmospheric properties. Identifying these feat…

HAMSTER: Hyperspectral Albedo Maps dataset with high Spatial and TEmporal Resolution

Giulia Roccetti, Luca Bugliaro, Felix Gödde +5

Surface albedo is an important parameter in radiative-transfer simulations of the Earth's system as it is fundamental for correctly calculating the energy budget of the planet. The…

Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya

Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39

Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…

A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys

Antoine Grandjean, A. -M. Lagrange, N. Meunier +13

The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
