A theoretical and observational study of the formation and evolution of planetary systems and extrasolar planets [PDF]
, 1999 The recent discoveries of extrasolar giant planets (planets like Jupiter orbiting other stars like our Sun) at small distances from their central stars have revitalized the fields of planet and planetary system formation.

Near the Runaway: The Climate and Habitability of Teegarden’s Star b
The Astrophysical Journal LettersTeegarden’s Star b, a nearby terrestrial world receiving an Earth-like instellation, is a prime candidate for next-generation observatories targeting temperate exoplanets in their habitable zones.

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.

A water budget dichotomy of rocky protoplanets from ²⁶Al-heating [PDF]
, 2019 In contrast to the water-poor inner solar system planets, stochasticity during planetary formation (Alibert & Benz 2017; Raymond& Izidoro 2017) and order of magnitude deviations in exoplanet volatile contents (Kaltenegger 2017) suggest ...

LHS 475 b: A Potential Venus Analog Orbiting a Nearby M Dwarf
The Astronomical JournalBased on photometric observations by TESS, we present the discovery of a potential Venus analog transiting LHS 475, an M3 dwarf located 12.5 pc from the Sun. The mass of the star is 0.274 ± 0.015 M _☉ .

Earth's Alfvén Wings Driven by the April 2023 Coronal Mass Ejection
Geophysical Research Letters, Volume 51, Issue 14, 28 July 2024.Abstract We report a rare regime of Earth's magnetosphere interaction with sub‐Alfvénic solar wind in which the windsock‐like magnetosphere transforms into one with Alfvén wings. In the magnetic cloud of a Coronal Mass Ejection (CME) on 24 April 2023, NASA's Magnetospheric Multiscale mission distinguishes the following features: (a) unshocked and ...

Tidal Evolution of Extrasolar Moons and Its Applications [PDF]
, 2014 In this thesis, we consider tidal evolution of extrasolar moons of star-planet-moon systems. First, we formulated tidal decay lifetimes for hypothetical moons with both lunar and stellar tides.
