THE ANGLO-AUSTRALIAN PLANET SEARCH. XXI. A GAS-GIANT PLANET IN A ONE YEAR ORBIT AND THE HABITABILITY OF GAS-GIANT SATELLITES [PDF]

open access: yes, 2011
We have detected the Doppler signature of a gas-giant exoplanet orbiting the star HD 38283, in an eccentric orbit with a period of almost exactly one year (P = 363.2 ± 1.6 d, m sin i = 0.34 ± 0.02 M Jup, e = 0.41 ± 0.16).

Overcoming the Trade‐Off Between Magnetic Coupling and Electrical Insulation in Soft Magnetic Materials via Nanochain Engineering

open access: yesAdvanced Science, EarlyView.
This study employs a nanochain engineering approach combined with an in situ oxidation strategy to fabricate self‐insulating iron‐based magnetic nanochains, addressing the challenge of balancing magnetic coupling and electrical insulation in soft magnetic materials.

The Long-term Evolution of the Jovian Irregular Satellites

open access: yes, 2010
International audienceInterested in the global dynamical structure of the Jovian irregular satellites and their chaotic evolutions, we have performed numerical integrations of the satellites along with an indicator of chaos (MEGNO), to give a clear ...

Three-Body Capture of Jupiter's Irregular Satellites and Resonant History of the Galilean Satellites [PDF]

open access: yes, 2010
We examine the capture of small, irregular satellites, which, with their distant, eccentric, and inclined paths, must have originated in heliocentric orbits.

Dark Satellites and the Morphology of Dwarf Galaxies [PDF]

open access: yes, 2012
One of the strongest predictions of the Delta CDM cosmological model is the presence of dark satellites orbiting all types of galaxies. We focus here on the dynamical effects of such satellites on disky dwarf galaxies, and demonstrate that these ...

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Model for Determining the Origin of Lunar Volatiles Based on Their Composition: Application to NASA’s VIPER and Other Landed Missions

open access: yesThe Planetary Science Journal
Lunar volatiles provide a potentially pristine record of the history of the Earth–Moon system in terms of both geologic activity and delivery of volatiles from the outer solar system.

Irregular satellites of Jupiter: capture configurations of binary-asteroids

open access: yes, 2011
The origins of the irregular satellites of the giant planets are an important piece of the huge 'puzzle' that is the theory of Solar system formation. They are not in situ formation objects, around the planet, as one believes the regular satellites to be.

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

The Origin of Neptune's Unusual Satellites from a Planetary Encounter

open access: yes, 2020
The Neptunian satellite system is unusual, comprising Triton, a large (∼2700 km) moon on a close-in, circular, yet retrograde orbit, flanked by Nereid, the largest irregular satellite (∼300 km) on a highly eccentric orbit.
