Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 11593-11606 (2020)

Atmospheric high-viscosity organic particles (HVOPs) were observed in samples of ambient aerosols collected in April and May 2016 in the Southern Great Plains of the United States. These particles were apportioned as either airborne soil organic part

Single-star Warm-Jupiter Systems Tend to Be Aligned, Even around Hot Stellar Hosts: No T eff–λ Dependency

Publikováno v: The Astrophysical Journal Letters, Vol 973, Iss 1, p L21 (2024)

The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity. However, the sample size of warm-

The PFS View of TOI-677 b: A Spin–Orbit Aligned Warm Jupiter in a Dynamically Hot System

Autor: Qingru Hu, Malena Rice, Xian-Yu Wang, Songhu Wang, Avi Shporer, Johanna K. Teske, Samuel W. Yee, R. Paul Butler, Stephen Shectman, Jeffrey D. Crane, Karen A. Collins, Kevin I. Collins

Publikováno v: The Astronomical Journal, Vol 167, Iss 4, p 175 (2024)

TOI-677 b is part of an emerging class of “tidally detached” gas giants ( a / R _⋆ ≳ 11) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet formation, which must

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems

Publikováno v: The Astronomical Journal, Vol 166, Iss 6, p 266 (2023)

The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientatio

A Transiting Super-Earth in the Radius Valley and an Outer Planet Candidate Around HD 307842

Publikováno v: The Astronomical Journal, Vol 166, Iss 1, p 32 (2023)

We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial velocity (RV) measurements constrain the mass to be ${9.67}_{-0.82}^{+0.83}\

TOI-1075 b: A Dense, Massive, Ultra-short-period Hot Super-Earth Straddling the Radius Gap

Publikováno v: The Astronomical Journal, Vol 165, Iss 2, p 47 (2023)

Populating the exoplanet mass–radius diagram in order to identify the underlying relationship that governs planet composition is driving an interdisciplinary effort within the exoplanet community. The discovery of hot super-Earths—a high-temperat

Doppler Constraints on Planetary Companions to Nearby Sun-like Stars: An Archival Radial Velocity Survey of Southern Targets for Proposed NASA Direct Imaging Missions

Publikováno v: The Astronomical Journal, Vol 165, Iss 4, p 176 (2023)

Directly imaging temperate rocky planets orbiting nearby, Sun-like stars with a 6 m class IR/O/UV space telescope, recently dubbed the Habitable Worlds Observatory, is a high-priority goal of the Astro2020 Decadal Survey. To prepare for future direct
