Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e

open access: yesThe Astronomical Journal
Planets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

The Rings of Saturn

open access: yes, 2018
One could become an expert on Saturn's iconic rings pretty easily in the early 1970s, as very little was known about them beyond the distinction between the A, B, and C rings, and the Cassini Division or "gap" between rings A and B (Alexander, 1962; Bobrov, 1970).

Differentiating Plumes and Local Torus Segments of Enceladus

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Seismology of Giant Planets: General Overview and Results from the Kepler K2 Observations of Neptune

open access: yesEPJ Web of Conferences, 2017
For this invited contribution, I was asked to give an overview about the application of helio and aster-oseismic techniques to study the interior of giant planets, and to specifically present the recent observations of Neptune by Kepler K2.

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.

Current State of Evidence for Implant Placement and Loading in Partially Edentulous Patients: A Systematic Review

open access: yesClinical Implant Dentistry and Related Research, Volume 28, Issue 1, February 2026.
ABSTRACT Objectives To systematically review the updated evidence for the clinical outcome of fixed implant prostheses treated with different combinations of implant placement and loading protocols in partially edentulous patients. Materials and Methods An electronic search was performed in Medline, Embase, and Central to identify studies of implants ...

Main-oval Auroral Emission from a T6 Brown Dwarf: Observations, Modeling, and Astrometry

open access: yesThe Astrophysical Journal
From a series of 5 GHz Very Long Baseline Array (VLBA) radio observations taken over a 1 yr span, we present the detection of compact, highly polarized radio emission from the T6 brown dwarf WISE J112254.72+255022.2, compatible with electron cyclotron ...

The Untrue Island Re-visited: Three Encounters with Orford Ness

open access: yesAmerican and British Studies Annual
The present paper deals with three texts inspired by the topography and secretive military history of the East Anglian offshore shingle spit Orford Ness. Each may be considered a specific example of a hybrid genre.

The Bombardment History of the Giant Planet Satellites

open access: yesThe Planetary Science Journal
The origins of the giant planet satellites are debated, with scenarios including formation from a protoplanetary disk, sequential assembly from massive rings, and recent accretion after major satellite–satellite collisions.
