Consequences of the Solar System passage through dense interstellar clouds [PDF]

open access: yesAnnales Geophysicae, 2003
Several consequences of the passage of the solar system through dense interstellar molecular clouds are discussed. These clouds, dense (more than 100 cm-3), cold (10–50 K) and extended (larger than 1 pc), are characterized by a gas-to-dust mass ...

Formation, Structure, and Detectability of the Geminids Meteoroid Stream

open access: yesThe Planetary Science Journal, 2023
The Geminids meteoroid stream produces one of the most intense meteor showers at Earth. It is an unusual stream in that its parent body is understood to be an asteroid, (3200) Phaethon, unlike most streams, which are formed via ongoing cometary activity.

Investigating Coronal Holes and CMEs as Sources of Brightness Depletion Detected in PSP/WISPR Images

open access: yesThe Astrophysical Journal, 2023
The Parker Solar Probe (PSP) mission provides a unique opportunity to observe the solar corona from distances below 20 R _☉ . In this work, we utilize white light images from the Wide-field Imager for Solar PRobe aboard the PSP from solar encounters 10 ...

Heliocentric distance dependence of zodiacal light observed by Hayabusa2#

open access: yesEarth, Planets and Space, 2023
Zodiacal light (ZL) is sunlight scattered by interplanetary dust particles (IDPs) at optical wavelengths. The spatial distribution of IDPs in the Solar System may hold an important key to understanding the evolution of the Solar System and material ...

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 ...

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

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

Dust observations with antenna measurements and its prospects for observations with Parker Solar Probe and Solar Orbiter [PDF]

open access: yesAnnales Geophysicae, 2019
The electric and magnetic field instrument suite FIELDS on board the NASA Parker Solar Probe and the radio and plasma waves instrument RPW on the ESA Solar Orbiter mission that explore the inner heliosphere are sensitive to signals generated by dust ...
