Terrestrial planet formation in low eccentricity warm-Jupiter systems
, 2009 We examine the effect of giant planet migration on the formation of inner terrestrial planet systems. We consider situations in which the giant planet halts migration at semi-major axes in the range 0.13 - 1.7 AU due to gas disk dispersal. An N-body code

RAMUS: Printable, Mechanically‐Tunable and Biodegradable Cellulose‐Mediated Composites
Advanced Materials Interfaces, EarlyView.Ramus, a Latin term meaning “branch,” develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based biomaterial composites able to mediate their structural capacity from micro to macroscale. Abstract Ramus develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based ...

JWST Directly Images Giant Planet Candidates Around Two Metal-polluted White Dwarf Stars
The Astrophysical Journal LettersWe report the discovery of two directly imaged, giant planet candidates orbiting the metal-rich, hydrogen atmosphere white dwarfs WD 1202−232 and WD 2105−82. JWST’s Mid-Infrared Instrument (MIRI) data on these two stars show a nearby resolved source at a

Masses and Densities of Dwarf Planet Satellites Measured with ALMA
The Planetary Science Journal, 2023 We have used the Atacama Large Millimeter/submillimeter Array to measure precise absolute astrometric positions and detect the astrometric wobble of dwarf planet Orcus and its satellite Vanth over a complete orbit.

The effect of planet-planet scattering on the survival of exomoons
, 2013 Compared to the giant planets in the solar system, exoplanets have many remarkable properties such as the prevalence of giant planets on eccentric orbits and the presence of hot Jupiters. Planet-planet scattering (PPS) between giant planets is a possible

Advanced Materials Technologies, EarlyView.Inkjet printing enables uniform, reproducible, and stable deposition of nitrogen‐doped graphene acid (NGA) on screen‐printed electrodes, outperforming traditional drop‐casting. The resulting electrochemical sensor exhibits enhanced sensitivity, long‐term stability, and efficient imidacloprid detection.

The Astrophysical Journal LettersGiant planet atmospheres are thought to reflect the gas phase composition of the disk when and where they formed. However, these atmospheres may also be polluted via solid accretion or ice sublimation in the disk.

Can planetary instability explain the Kepler dichotomy?
, 2012 The planet candidates discovered by the Kepler mission provide a rich sample to constrain the architectures and relative inclinations of planetary systems within approximately 0.5 AU of their host stars.

Advanced Sustainable Systems, EarlyView.Biobased bamboo shavings are used to immobilize Lewis base catalysts for CO2 valorization. Two methods are investigated for immobilization of catalysts: covalent isocyanate coupling and silane condensation. The isocyanate method achieves 100% conversion of cyclic carbonate starting from epoxides, whereas the silane method yields glycerol carbonate with

The Gap–Giant Association: Are Planets Hiding in the Gaps?
The Astrophysical JournalA handful of stars are known to host both an inner system of multiple transiting planets and an outer giant planet. These systems all feature a prominent gap between the orbits of two of the transiting planets, distinguishing them from typical ...
