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 origin and nature of Neptune-like planets orbiting close to solar type stars [PDF]
, 2005 The sample of known exoplanets is strongly biased to masses larger than the ones of the giant gaseous planets of the Solar System. Recently, the discovery of two extrasolar planets of considerably lower masses around the nearby Stars GJ 436 and ρ Cancri ...

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 ...

Journal of Geophysical Research: Planets, Volume 129, Issue 3, March 2024.Abstract Toroidal atmospheres and exospheres characterized at exoplanets may be fueled by volcanically active exomoons, often referred to as exo‐Ios. We study the neutral outgassing and volatile evolution of a close‐orbiting, evaporating satellite at eight candidate exoplanet‐exomoon systems WASP‐49,‐96,‐69,‐17 b, XO‐2N b, HAT‐P‐1 b, HD‐189733 b, and ...

On the Terminal Rotation Rates of Giant Planets [PDF]
, 2018 Within the general framework of the core-nucleated accretion theory of giant planet formation, the conglomeration of massive gaseous envelopes is facilitated by a transient period of rapid accumulation of nebular material.

On the atmospheres of Saturn and cold gas giant extrasolar planets [PDF]
, 2018 Over the past few decades, short-period giant planets have been discovered in extrasolar planetary systems, allowing for new tests of planetary evolution theories.

The Astronomical JournalRecent discoveries of transiting giant exoplanets ( R _p ≳ 8 R _⊕ ) around M dwarfs present an opportunity to investigate their atmospheric compositions and explore how such massive planets form around low-mass stars contrary to the prediction from ...

Orbits and Interiors of Planets [PDF]
, 2012 The focus of this thesis is a collection of problems of timely interest in orbital dynamics and interior structure of planetary bodies. The first three chapters are dedicated to understanding the interior structure of close-in, gaseous extrasolar ...
