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

Dynamical Mass of the Exoplanet Host Star HR 8799
The Astronomical Journal, 2022 Abstract HR 8799 is a young A5/F0 star hosting four directly imaged giant planets at wide separations (∼16–78 au), which are undergoing orbital motion and have been continuously monitored with adaptive optics imaging since their discovery over a decade ago. We present a dynamical mass of HR 8799 using 130 epochs of relative astrometry of

Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet. [PDF]
NatureAs the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization 1,2,3. It has also been the anchor point for much of our theoretical understanding of exoplanet atmospheres from composition 4 ...

Validating AU Microscopii d with Transit Timing Variations
The Astronomical Journal, 2023 AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar activity.

Regular and chaotic orbits in the dynamics of exoplanets [PDF]
The European Physical Journal Special Topics, 2016 Many of exoplanetary systems consist of more than one planet and the study of planetary orbits with respect to their long-term stability is very interesting. Furthermore, many exoplanets seem to be locked in a mean-motion resonance (MMR), which offers a phase protection mechanism, so that, even highly eccentric planets can avoid close encounters ...

A New Method for Studying Exoplanet Atmospheres Using Planetary Infrared Excess [PDF]
Astrophysical Journal, 2020 To date, the ability for observers to reveal the composition or thermal structure of an exoplanet’s atmosphere has rested on two techniques: high-contrast direct imaging and time-series observations of transiting exoplanets.

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