Formation of Asteroid (16) Psyche by a Giant Impact

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Evaporation of hot jupiters and hot neptunes [PDF]

open access: yesEPJ Web of Conferences, 2011
Among the nearly five hundred extra-solar planets known, almost 30% orbit closer than 0.1 AU from their parent star. We will review the observations and the corresponding models of the evaporation of these ‘hot jupiters’. The observations started with the discovery made with HST that the planet orbiting HD 209458 has an extended atmosphere of escaping ...

Optimising a current‐rate controlled flash sintering process for UO2 pellet fabrication

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Field assisted sintering techniques (FASTs) are currently being presented as an attractive alternative to the energy and time intensive fabrication routes employed for UO2 and MOx nuclear fuel manufacture. Current‐rate controlled flash sintering (CR‐FS) is a novel variant of typical flash sintering (FS) methods that permits heightened sample ...

Disentangling Metallicity Effects in Hot Jupiter Occurrence across Galactic Birth Radius and Phase-space Density

open access: yesThe Astronomical Journal
We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius ( R _birth ) and phase-space density in the Milky Way disk.

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Tidal and Magnetic Interactions between a Hot Jupiter and its Host Star in the Magnetospheric Cavity of a Protoplanetary Disk

open access: yes, 2009
We present a simplified model to study the orbital evolution of a young hot Jupiter inside the magnetospheric cavity of a proto-planetary disk. The model takes into account the disk locking of stellar spin as well as the tidal and magnetic interactions ...

Radial and azimuthal dynamics of the io plasma torus [PDF]

open access: yes, 2015
Thesis (M.S.) University of Alaska Fairbanks, 2015The moon Io orbits Jupiter emitting neutral particles from its volcanic surface. This emission is ionized and forms the Io plasma torus around Jupiter.

The center-to-limb variation across the Fraunhofer lines of HD 189733; Sampling the stellar spectrum using a transiting planet

open access: yes, 2015
The center-to-limb variation (CLV) describes the brightness of the stellar disk as a function of the limb angle. Across strong absorption lines, the CLV can vary quite significantly.
