Modelling cometary meteoroid stream traverses of the Martian Moons eXploration (MMX) spacecraft en route to Phobos

open access: yesEarth, Planets and Space, 2021
The Martian Moons Exploration (MMX) spacecraft is a JAXA mission to Mars and its moons Phobos and Deimos. MMX will be equipped with the Circum-Martian Dust Monitor (CMDM) which is a newly developed light-weight ( $$\mathrm {650\,g}$$ 650 g ) large area (

Grain Alignment and Rotational Disruption by Radiative Torques in Exoplanet Atmospheres

open access: yesThe Astrophysical Journal, 2023
Dust clouds are ubiquitous in the atmospheres of hot Jupiters and affect their observable properties. The alignment of dust grains in the clouds and resulting dust polarization provide a promising way to study the magnetic fields of exoplanets. Moreover,

Modeling the Motion and Distribution of Interstellar Dust inside the Heliosphere [PDF]

open access: yes, 1999
The interaction of dust grains originating from the local interstellar cloud with the environment inside the heliosphere is investigated. As a consequence of this interaction the spatial distribution of interstellar dust grains changes with time.

Characterization of the Ejecta from the NASA/DART Impact on Dimorphos: Observations and Monte Carlo Models

open access: yesThe Planetary Science Journal, 2023
The NASA Double Asteroid Redirection Test (DART) spacecraft successfully crashed on Dimorphos, the secondary component of the binary (65803) Didymos system. Following the impact, a large dust cloud was released, and a long-lasting dust tail developed. We

SEARCH OF THE Na IN THE REGION OF THE SUBLIMATION OF THE NEAR-SUN DUST

open access: yesOdessa Astronomical Publications, 2017
An evaluation of the Na number in the sublimation zone of the near-Sun interplanetary dust, based on a comparison with the intensity of the radiation of the Na in the Earth atmosphere, has been obtained.

The Mid-Infrared Spectrum of the Zodiacal and Exozodiacal Light [PDF]

open access: yes, 2003
The zodiacal light is the dominant source of the mid-infrared sky brightness seen from Earth, and exozodiacal light is the dominant emission from planetary and debris systems around other stars.

Unique, non‐Earthlike, meteoritic ion behavior in upper atmosphere of Mars

open access: yesGeophysical Research Letters, 2017
Interplanetary dust particles have long been expected to produce permanent ionospheric metal ion layers at Mars, as on Earth, but the two environments are so different that uncertainty existed as to whether terrestrial‐established understanding would ...

Meteorites and cosmic dust: Interstellar heritage and nebular processes in the early solar system

open access: yesEPJ Web of Conferences, 2012
Small solar system bodies like asteroids and comets have escaped planetary accretion. They are the oldest and best preserved witnesses of the formation of the solar system.

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.

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 ...
