Motion of dust ejected from the surface of asteroid (101955) Bennu

open access: yesHeliyon, 2020
From Jan. 6, 2019 to Feb. 18, 2019, OSIRIS-REx observed asteroid (101955) Bennu ejecting 11 plumes of dust, of which part is escaping and another part is re-captured by the asteroid.

Updating the Electrostatic Model for Dust Impact Detection with Antenna Instruments

open access: yesThe Astrophysical Journal
Antenna instruments deployed in space are known to be sensitive to dust impacts, and the detected signals can be used to characterize the dust populations within the solar system.

Eccentric Dust Ring in the IRS 48 Transition Disk

open access: yesThe Astrophysical Journal Letters, 2023
Crescent-shaped structures in transition disks hold the key to studying the putative companions to the central stars. The dust dynamics, especially that of different grain sizes, is important to understanding the role of pressure bumps in planet ...

Comprehensive and Open Assessment of Thermospheric Models During Geomagnetic Storm Times Within CCMC Framework

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract Thermospheric neutral density controls satellite drag in low Earth orbit and varies strongly during geomagnetic storms. We present a multi‐mission, phase‐resolved assessment of empirical and physics‐based thermosphere models using 151 storms from 2001 to 2023, including MSIS, DTM, JB2008, WAM‐IPE, WACCM‐X, GITM, CTIPe, and TIE‐GCM.

The Size-Frequency Distribution of the Zodiacal Cloud: Evidence from the Solar System Dust Bands [PDF]

open access: yes, 2000
Recent observations of the size-frequency distribution of zodiacal cloud particles obtained from the cratering record on the LDEF satellite (Love and Brownlee 1993) reveal a significant large particle population (100 micron diameter or greater) near 1 AU.

Model calculations for cosmogenic nuclides in meteorites and the lunar surface. 1. Long‐lived radionuclides

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 4, Page 600-620, April 2026.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 4, Page 644-663, April 2026.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

A Rotational Disruption Crisis for Zodiacal Dust

open access: yesThe Astrophysical Journal Letters
A systematic torque from anisotropic radiation can rapidly spin up irregular grains to the point of breakup. We apply the standard theory of rotational disruption from radiative torques to solar system grains, finding that grains with radii ∼0.03–3 μ m ...
