Highly Depleted Alkali Metals in Jupiter’s Deep Atmosphere
The Astrophysical Journal Letters, 2023 Water and ammonia vapors are known to be the major sources of spectral absorption at pressure levels observed by the microwave radiometer (MWR) on Juno. However, the brightness temperatures and limb darkening observed by the MWR at its longest-wavelength

Knudsen effusion mass spectrometry: Current and future approaches
Rapid Communications in Mass Spectrometry, Volume 38, Issue 14, 30 July 2024.Rationale Knudsen effusion mass spectrometry (KEMS) has been a powerful tool in physical chemistry since 1954. There are many excellent reviews of the basic principles of KEMS in the literature. In this review, we focus on the current status and potential growth areas for this instrumental technique.

The stability of short-period extrasolar giant planets [PDF]
, 2008 A three-dimensional coupled thermosphere-ionosphere model for extrasolar giant planets (EXOTIM) has been developed. This is the first such model reported in the literature.

Planet–Planet Scattering Explains the Mass–Eccentricity Relation of Warm Jupiters
The Astrophysical Journal LettersWarm Jupiters—giant planets with orbital periods of ∼10–365 days—exhibit a positive correlation between mass and eccentricity. We interpret this trend as the outcome of planet–planet scattering, representing a transition from collision-dominated ...

Small and Close-in Planets are Uncommon Around A-type Stars
The Astronomical JournalThe Kepler and K2 missions enabled robust calculations of planet occurrence rates around FGKM-type stars. However, these missions observed too few stars with earlier spectral types to tightly constrain the occurrence rates of planets orbiting hotter ...

The Astrophysical Journal Supplement Series, 2023 We present analysis of the atmospheres of 70 gaseous extrasolar planets via transit spectroscopy with Hubble’s Wide Field Camera 3 (WFC3). For over half of these, we statistically detect spectral modulation that our retrievals attribute to molecular ...

Journal of Geophysical Research: Space Physics, Volume 129, Issue 4, April 2024.Abstract Outward transport of plasma in the inner and middle magnetospheres of gas giants results from an interplay between mass loading from the inner dominant mass sources (volcanic moons), flux tube interchange in the centrifugally unstable magnetospheric plasma disk, turbulent heating of the plasma, and coupling between the equatorial plasma and ...

Two Extrasolar Planets from the Anglo‐Australian Planet Search
, 2002 We report the detection of two new extrasolar planets from the Anglo-Australian Planet Search around the stars HD 142 and HD 23079. The planet orbiting HD 142 has an orbital period of just under 1 yr, while that orbiting HD 23079 has a period of just ...
