Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems
The Astronomical Journal, 2023 The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

Exoplanet albedo spectra and colors as a function of planet phase, separation, and metallicity [PDF]
, 2010 First generation optical coronagraphic telescopes will obtain images of cool gas and ice giant exoplanets around nearby stars. The albedo spectra of exoplanets at planet-star separations larger than about 1 AU are dominated by reflected light to beyond 1

The observation of exoplanet transit events in China
EPJ Web of Conferences, 2011 We have carried out a research project on the exoplanet transit events at Yunnan Observatory. By using CCD cameras attached to 1m telescope of Yunnan Observatory and 85cm telescope of Xinglong station, NAOC, a group of exoplanet systems with transit ...

The Demographics of Terrestrial Planets in the Venus Zone
The Astronomical Journal, 2023 Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary ...

Gaia astrometry and exoplanetary science: DR2, (E)DR3, and beyond
Comptes Rendus. Physique, 2023 I review the recent impact of Gaia astrometry in the exoplanet field, both in terms of characterization of the orbits and masses of planetary systems and the properties of their host stars.

Extrasolar planets in stellar multiple systems
, 2012 Analyzing exoplanets detected by radial velocity or transit observations, we determine the multiplicity of exoplanet host stars in order to study the influence of a stellar companion on the properties of planet candidates.

The K2 and TESS Synergy. II. Revisiting 26 Systems in the TESS Primary Mission
The Astronomical Journal, 2023 The legacy of NASA’s K2 mission has provided hundreds of transiting exoplanets that can be revisited by new and future facilities for further characterization, with a particular focus on studying the atmospheres of these systems. However, the majority of
