Dynamics of Small Solar System Bodies and Exoplanets [PDF]
, 2010 The Gaia space mission to be operated in early 2012 by the European Space Agency (ESA), will make a huge step in our knowledge of the Sun's neighbor-hood, up to the Magellanic clouds. Somewhat closer, Gaia will also provide ma jor improvements in the science of asteroids, and more generally to our Solar System, either directly or indirectly.

The CoRoT Exoplanet program : status & results [PDF]
Detection and Dynamics of Transiting Exoplanets, St. Michel
l'Observatoire, France, Edited by F. Bouchy; R. D\'iaz; C. Moutou; EPJ Web of
Conferences, Volume 11, 2011, 2011 The CoRoT satellite is the first instrument hunting for planets from space. We will review the status of the CoRoT/Exoplanet program. We will then present the CoRoT exoplanetary systems and how they widen the range of properties of the close-in population and contribute to our understanding of the properties of planets.

Atmospheres on Nonsynchronized Eccentric-tilted Exoplanets. I. Dynamical Regimes [PDF]
The Astrophysical Journal, 2019 Abstract Relatively long-period, nonsynchronized planets—such as warm Jupiters—potentially retain the primordial rotation, eccentricity, and obliquity that might encapsulate information on planetary climate and formation processes. To date, there has not been a systematic study on climate patterns on these planets that will significantly

Highlights in the Study of Exoplanet Atmospheres [PDF]
Nature, 513, pp. 345-352, 2014, 2014 Exoplanets are now being discovered in profusion. However, to understand their character requires spectral models and data. These elements of remote sensing can yield temperatures, compositions, and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are achieved.

Eccentric debris belts reveal the dynamical history of the companion exoplanet
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT In recent years, a number of eccentric debris belts have been observed in extrasolar systems. The most common explanation for their shape is the presence of a nearby eccentric planetary companion. The gravitational perturbation from such a companion would induce periodic eccentricity variations on the planetesimals in the belt ...

Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations
, 2011 We use three-dimensional simulations to study the atmospheric circulation on the first Earth-sized exoplanet discovered in the habitable zone of an M star.

NIMBUS: The Near-Infrared Multi-Band Ultraprecise Spectroimager for SOFIA [PDF]
, 2012 We present a new and innovative near-infrared multi-band ultraprecise spectroimager (NIMBUS) for SOFIA. This design is capable of characterizing a large sample of extrasolar planet atmospheres by measuring elemental and molecular abundances during ...

Exoplanets Torqued by the Combined Tides of a Moon and Parent Star [PDF]
, 2018 In recent years, there has been interest in Earth-like exoplanets in the habitable zones of low mass stars ($\sim0.1-0.6\,M_\odot$). Furthermore, it has been argued that a large moon may be important for stabilizing conditions on a planet for life. If these two features are combined, then an exoplanet can feel a similar tidal influence from both its ...

The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet β Pictoris b from Combined Direct Imaging and Astrometry [PDF]
The Astronomical Journal, 2020 Abstract We present new observations of the planet β Pictoris b from 2018 with the Gemini Planet Imager (GPI), the first GPI observations following conjunction. Based on these new measurements, we perform a joint orbit fit to the available relative astrometry from ground-based imaging, the Hipparcos Intermediate Astrometric Data (IAD ...
