Solar Energetic Particle Track-production Rates at 1 au: Comparing In Situ Particle Fluxes with Lunar Sample-derived Track Densities

open access: yesThe Astrophysical Journal Letters, 2023
Heavy ( Z > 26) solar energetic particles (SEPs) with energies ∼1 MeV nucleon ^−1 are known to leave visible damage tracks in meteoritic materials. The density of such “solar flare tracks” in lunar and asteroidal samples has been used as a measure of a ...

Interplanetary Dust as a Foreground for the LiteBIRD CMB Satellite Mission

open access: yesThe Open Journal of Astrophysics, 2021
As ever-more sensitive experiments are made in the quest for primordial CMB B Modes, the number of potentially significant astrophysical contaminants becomes larger as well. Thermal emission from interplanetary dust, for example, has been detected by the

Investigation of Dust Grains by Optical Tweezers for Space Applications

open access: yesThe Astrophysical Journal, 2022
Cosmic dust plays a dominant role in the universe, especially in the formation of stars and planetary systems. Furthermore, the surface of cosmic dust grains is the benchwork where molecular hydrogen and simple organic compounds are formed. We manipulate

Prediction of the In-Situ Dust Measurements of the Stardust Mission to Comet 81P/Wild 2 [PDF]

open access: yes, 1999
We predict the amount of cometary, interplanetary, and interstellar cosmic dust that is to be measured by the Cometary and Interstellar Dust Analyzer (CIDA) and the aerogel collector on-board the Stardust spacecraft during its fly-by of comet P/Wild 2 ...
