A window for water-hydrogen demixing on warm metal-rich sub-Neptunes
Caroline Piaulet-Ghorayeb, Daniel P. Thorngren, Eliza M. -R. Kempton +4
Sub-Neptunes represent the largest exoplanet demographic, yet their bulk compositions remain poorly understood. Recent studies suggested that only very cold planets, such as Uranus…
BOWIE-ALIGN: Exploring degeneracies in the muted transmission spectrum of the aligned hot Jupiter NGTS-2b with NIRSpec/G395H
Charlotte Fairman, Hannah R. Wakeford, Alastair B. Claringbold +15
We present the first atmospheric observation and characterisation of the aligned, 1468 K hot Jupiter, NGTS-2b, with one JWST NIRSpec/G395H transit. These observations complete the…
Hot Jupiters are Inflated Primarily by Shallow Heating
Stephen P. Schmidt, Daniel P. Thorngren, Kevin C. Schlaufman
The unexpectedly large radii of transiting hot Jupiters have led to many proposals for the physical mechanisms responsible for heating their interiors. While it has been shown that…
The Hot Jupiter Radius Anomaly and Stellar Connections
Daniel P. Thorngren
The extremely close proximity of hot Jupiters to their parent stars has dramatically affected both their atmospheres and interiors, inflating them to up to twice the radius of Jupi…
The Impact of Irradiation on the Radius and Thermal Evolution of Transiting Brown Dwarfs
Sagnick Mukherjee, Jonathan J. Fortney, Theron W. Carmichael +2
Masses and radii of transiting brown dwarfs can be measured directly in contrast to isolated field brown dwarfs, whose mass and radius inferences are model dependent. Therefore, tr…
Bayesian Model Comparison and Significance: Widespread Errors and how to Correct Them
Daniel P. Thorngren, David K. Sing, Sagnick Mukherjee
Bayes factors have become a popular tool in exoplanet spectroscopy for testing atmosphere models against one another. We show that the commonly used method for converting these val…
