TOI-1670 c, a 40 day Orbital Period Warm Jupiter in a Compact System, Is Well Aligned

open access: yesThe Astrophysical Journal Letters, 2023
We report the measurement of the sky-projected obliquity angle λ of the warm Jovian exoplanet TOI-1670 c via the Rossiter–McLaughlin effect. We observed the transit window during UT 2023 April 20 for 7 continuous hours with NEID on the 3.5 m WIYN ...

Classification of Trajectories in a Two-planet Exosystem Using the Generalized Three-body Problem

open access: yesThe Astrophysical Journal, 2023
We deploy the theory of the generalized three-body problem to describe an exosystem composed of a host star, a transiting Jupiter-sized exoplanet, and an Earth-sized exoplanet.

Observations of Extrasolar Planets During the non-Cryogenic Spitzer Space Telescope Mission [PDF]

open access: yes, 2007
Precision infrared photometry from Spitzer has enabled the first direct studies of light from extrasolar planets, via observations at secondary eclipse in transiting systems.

Atmospheres on Nonsynchronized Eccentric-tilted Exoplanets. I. Dynamical Regimes [PDF]

open access: yesThe 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

Giant Outer Transiting Exoplanet Mass (GOT ’EM) Survey. III. Recovery and Confirmation of a Temperate, Mildly Eccentric, Single-transit Jupiter Orbiting TOI-2010

open access: yesThe Astronomical Journal, 2023
Large-scale exoplanet surveys like the Transiting Exoplanet Survey Satellite (TESS) mission are powerful tools for discovering large numbers of exoplanet candidates.

Eccentric debris belts reveal the dynamical history of the companion exoplanet

open access: yesMonthly 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 ...

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.

The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet β Pictoris b from Combined Direct Imaging and Astrometry [PDF]

open access: yesThe 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 ...

Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations

open access: yes, 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.
