African Decolonial Theory: A Conversation
Antipode, Volume 58, Issue 2, March 2026.Abstract Antipode has become a key platform for engaging with decolonial and anticolonial scholarship, as well as adjacent fields such as Black geographies, Indigenous studies, Latin American feminism, and work on settler‐colonialism. African reference points in this literature, however, have been far less common, both in the journal and more broadly ...

Mercury's Circumsolar Dust Ring as an Imprint of a Recent Impact
The Planetary Science Journal, 2023 A circumsolar dust ring has been recently discovered close to the orbit of Mercury. There are currently no hypotheses for the origin of this ring in the literature, so we explore four different origin scenarios here: the dust originated from (1) the ...

Sources of Interplanetary Dust [PDF]
International Astronomical Union Colloquium, 1996 AbstractAsteroids, comets and interstellar dust are possible sources of the particles that constitute the dust in the inner solar system. Each of these components gives rise to particular, characteristic features, the amplitudes of which can be used to estimate the size of the associated source.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Obtaining the Strength of the Magnetic Field from E- and B-Modes of Dust Polarization
The Astrophysical Journal, 2023 We perform numerical simulations of supersonic magnetohydrodynamic (MHD) turbulence and calculate Fourier power spectra of E - and B -modes arising from dust polarization. We pay close attention to the ratio of E -mode to B -mode spectra (a.k.a.

Determination of the Far-Infrared Cosmic Background Using COBE/DIRBE and WHAM Data
, 2007 Determination of the cosmic infrared background (CIB) at far infrared wavelengths using COBE/DIRBE data is limited by the accuracy to which foreground interplanetary and Galactic dust emission can be modeled and subtracted. Previous determinations of the

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Preparation, analysis and release of simulated interplanetary grains into low Earth orbit [PDF]
, 1985 Astronomical observations which reflect the optical and dynamical properties of interstellar and interplanetary grains are the primary means of identifying the shape, size, and the chemistry of extraterrestrial grain materials.

Dust Ablation on the Giant Planets: Consequences for Stratospheric Photochemistry
, 2017 Ablation of interplanetary dust supplies oxygen to the upper atmospheres of Jupiter, Saturn, Uranus, and Neptune. Using recent dynamical model predictions for the dust influx rates to the giant planets (Poppe, A.R.~et al.~[2016], Icarus 264, 369), we ...
