NIMBUS: The Near-Infrared Multi-Band Ultraprecise Spectroimager for SOFIA [PDF]

open access: yes, 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 ...

Secular spin-axis dynamics of exoplanets [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. Seasonal variations and climate stability of a planet are very sensitive to the planet obliquity and its evolution. This is of particular interest for the emergence and sustainability of land-based life, but orbital and rotational parameters of exoplanets are still poorly constrained.

Secular orbital dynamics of the innermost exoplanet of the $$\upsilon $$-Andromedæ system

open access: yesCelestial Mechanics and Dynamical Astronomy, 2023
Abstract We introduce a quasi-periodic restricted Hamiltonian to describe the secular motion of a small-mass planet in a multi-planetary system. In particular, we refer to the motion of $$\upsilon $$

Tidal dynamics of transiting exoplanets [PDF]

open access: yesProceedings of the International Astronomical Union, 2010
AbstractTransits give us the mass, radius, and orbital properties of the planet, all of which inform dynamical theories. Two properties of the hot Jupiters suggest they had a dramatic origin via tidal damping from high eccentricity. First, the tidally circularized planets (in the 1-4 day pile-up) lie along a relation or boundary in the mass-period ...

The Diversity of Exoplanets: From Interior Dynamics to Surface Expressions [PDF]

open access: yesElements, 2021
The coupled interior–atmosphere system of terrestrial exoplanets remains poorly understood. Exoplanets show a wide variety of sizes, densities, surface temperatures, and interior structures, with important knock-on effects for this coupled system. Many exoplanets are predicted to have a “stagnant lid” at the surface, with a rigid stationary crust ...

Effects of Bulk Composition on the Atmospheric Dynamics on Close-in Exoplanets [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract Super Earths and mini Neptunes likely have a wide range of atmospheric compositions, ranging from low molecular mass atmospheres of H2 to higher molecular atmospheres of water, CO2, N2, or other species. Here we systematically investigate the effects of atmospheric bulk compositions on temperature and wind distributions for ...

DIRECT MEASURE OF RADIATIVE AND DYNAMICAL PROPERTIES OF AN EXOPLANET ATMOSPHERE [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT Two decades after the discovery of 51 Peg b, the formation processes and atmospheres of short-period gas giants remain poorly understood. Observations of eccentric systems provide key insights on those topics as they can illuminate how a planet’s atmosphere responds to changes in incident flux.

Exclusion of Stellar Companions to Exoplanet Host Stars [PDF]

open access: yes, 2017
Given the frequency of stellar multiplicity in the solar neighborhood, it is important to study the impacts this can have on exoplanet properties and orbital dynamics.
