A Scaling Law for the Orbital Architecture of Planetary Systems Formed by Gravitational Scattering and Collisions

The Astrophysical Journal Letters
In the standard formation models of terrestrial planets in the solar system and close-in super-Earths in nonresonant orbits recently discovered by exoplanet observations, planets are formed by giant impacts of protoplanets or planetary embryos after the ...

Becoming climate sentinels

American Ethnologist, EarlyView.
Abstract In South Korea, forest scientists refashion themselves as “climate sentinels” as they confront subtle yet disquieting shifts in plant seasonality brought about by climate change. Unlike traditional sentinels, who watch for external threats from a frontier, climate sentinels face ecological anomalies and surprises—such as untimely flowering ...

Planets Around Solar Twins/Analogs (PASTA). I. High-precision Stellar Chemical Abundances for 17 Planet-hosting Stars and the Condensation Temperature Trend

The Astrophysical Journal
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 solar-like stars hosting ...

Recent advances in the interior structure of the gas giants

地球与行星物理论评
Jupiter and Saturn, as the gas giants of our solar system, account for over 90% of the total mass beyond the Sun and hold most of the system's angular momentum, playing a crucial role in the early history of the solar system.

Dependencies of Mantle Shock Heating in Pairwise Accretion

The Astrophysical Journal Letters, 2021
The final assembly of planets involves mutual collisions of large similar-sized protoplanets (“giant impacts”), setting the stage for modern geologic and atmospheric processes.

Workplace Health and Safety in Teal‐Collar Jobs: How Blue‐Collar Men Working With Green Technology Embrace a Shifting Culture of Masculinity

Gender, Work &Organization, EarlyView.
ABSTRACT Masculinity is often portrayed as a barrier to shifting away from fossil fuels because jobs in extractive industries represent a nostalgic masculine breadwinner identity. Accordingly, proposals for a just energy transition have provoked backlash aimed at protecting against perceived threats to manhood.

NIRCam Yells at Cloud: JWST MIRI Imaging Can Directly Detect Exoplanets of the Same Temperature, Mass, Age, and Orbital Separation as Saturn and Jupiter

The Astrophysical Journal Letters
NIRCam and MIRI coronagraphy has successfully demonstrated the ability to directly image young sub-Jupiter-mass and mature gas giant exoplanets. However, these modes struggle to reach the sensitivities needed to find the population of cold giant planets ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

Effects of Outer Giant Planets on In Situ Formation of Inner Super-Earths

The Astrophysical Journal
Recent studies have found an observational correlation between the presence of outer giant planets and inner super-Earths, which implies that outer giants do not suppress the formation of super-Earths.

Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.
