Helium Atmospheres on Warm Neptune- and Sub-Neptune-Sized Exoplanets and Applications to GJ 436 b [PDF]

open access: yes, 2015
Warm Neptune- and sub-Neptune-sized exoplanets in orbits smaller than Mercury's are thought to have experienced extensive atmospheric evolution. Here we propose that a potential outcome of this atmospheric evolution is the formation of helium-dominated ...

The Locus Algorithm IV: Performance metrics of a grid computing system used to create catalogues of optimised pointings [PDF]

open access: yes, 2020
This paper discusses the requirements for and performance metrics of the the Grid Computing system used to implement the Locus Algorithm to identify optimum pointings for differential photometry of 61,662,376 stars and 23,779 quasars. Initial operational

Mission Design of an Aperture-Synthetic Interferometer System for Space-Based Exoplanet Exploration

open access: yesSpace: Science & Technology, 2022
In recent years, exoplanet detection has become the technological frontier in the field of astronomy, because it provides evidence of the origin of life and the future human habitable exoplanet.

High Accuracy Molecular Line Lists for Studies of Exoplanets and Other Hot Atmospheres

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The desire to characterize and model the atmospheres of the many extrasolar planets that have been discovered over the last three decades is a major driver of current astronomy.

Bayesian analysis of exoplanet and binary orbits

open access: yes, 2012
We introduce BASE (Bayesian astrometric and spectroscopic exoplanet detection and characterisation tool), a novel program for the combined or separate Bayesian analysis of astrometric and radial-velocity measurements of potential exoplanet hosts and ...

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.

Asteroseismology of Exoplanet Host Stars

open access: yes, 2015
Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

Ponderings on the Possible Preponderance of Perpendicular Planets

open access: yesThe Astrophysical Journal Letters, 2023
Misalignments between planetary orbits and the equatorial planes of their host stars are clues about the formation and evolution of planetary systems. Earlier work found evidence for a peak near 90° in the distribution of stellar obliquities, based on ...
