Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System

open access: yesThe Astronomical Journal, 2023
The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

Evidence for unresolved exoplanet-hosting binaries in Gaia DR2

open access: yes, 2018
This note describes an effort to detect additional stellar sources in known transiting exoplanet (TEP) systems, which are unresolved or barely resolved in the Gaia Data Release 2 (DR2) catalogue.

Transiting Exoplanet Studies and Community Targets for JWST's Early Release Science Program [PDF]

open access: yes, 2016
The James Webb Space Telescope will revolutionize transiting exoplanet atmospheric science due to its capability for continuous, long-duration observations and its larger collecting area, spectral coverage, and spectral resolution compared to existing ...

Altitude Profile and Isotopic Composition for N2 From Pioneer Venus Mass Spectra

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract We report the highest resolution altitude profile and isotopic composition for N2 at Venus, to date. These results were obtained through re‐analysis of data acquired by the Pioneer Venus Large Probe Neutral Mass Spectrometer (LNMS). The N2 is non‐uniformly mixed across the clouds and sub‐cloud atmosphere (∼59–15 km) yet uniformly mixed across ...

Infrared Observations During the Secondary Eclipse of HD 209458b: I. 3.6-Micron Occultation Spectroscopy Using the VLT [PDF]

open access: yes, 2002
We search for an infrared signature of the transiting extrasolar planet HD 209458b during secondary eclipse. Our method, which we call `occultation spectroscopy,' searches for the disappearance and reappearance of weak spectral features due to the ...

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters

open access: yesThe Astrophysical Journal
The orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Kepler Observations of the Three Pre-Launch Exoplanet Candidates: Discover of Two Eclipsing Binaries and a New Exoplanet [PDF]

open access: yes, 2010
Three transiting exoplanet candidate stars were discovered in a ground-based photometric survey prior to the launch of NASA's Kepler mission. Kepler observations of them were obtained during Quarter 1 of the Kepler mission.

Observations of Exoplanet Atmospheres

open access: yes, 2015
Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and
