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

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.

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 ...

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 ...

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 ...

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 ...

High Resolution Transmission Spectroscopy as a Diagnostic for Jovian Exoplanet Atmospheres: Constraints from Theoretical Models

, 2014
We present high resolution transmission spectra of giant planet atmospheres from a coupled 3-D atmospheric dynamics and transmission spectrum model that includes Doppler shifts which arise from winds and planetary motion. We model jovian planets covering

Photochemical Hazes Dramatically Alter Temperature Structure and Atmospheric Circulation in 3D Simulations of Hot Jupiters

The Astrophysical Journal, 2023
Photochemical hazes are expected to form in hot Jupiter atmospheres and may explain the strong scattering slopes and muted spectral features observed in the transmission spectra of many hot Jupiters.
