Dust release from cold ring particles as a mechanism of spoke formation in Saturn's rings
Naoyuki Hirata, Hiroshi Kimura, Keiji Ohtsukia
Spokes in Saturn's rings are radially-extended structures consisting of dust grains. Although spacecraft and space telescope observations have revealed various detailed features of…
Electrostatic Dust Ejection From Asteroid (3200) Phaethon With the Aid of Mobile Alkali Ions at Perihelion
Hiroshi Kimura, Katsuhito Ohtsuka, Shota Kikuchi +12
The asteroid (3200) Phaethon is known to be the parent body of the Geminids, although meteor showers are commonly associated with the activity of periodic comets. What is most pecu…
Do twin spectral peaks of olivine particles in the thermal infrared diagnose their sizes and porosities?
Hiroshi Kimura, Johannes Markkanen, Ludmilla Kolokolova +4
A well-established constraint on the size of non-porous olivine grains or the porosity of aggregates consisting of small olivine grains from prominent narrow peaks in thermal infra…
Modelling cometary meteoroid stream traverses of the Martian Moons eXploration (MMX) spacecraft en route to Phobos
Harald Krüger, Masanori Kobayashi, Peter Strub +5
The Martian Moons Exploration (MMX) spacecraft is a JAXA mission to Mars and its moons Phobos and Deimos. MMX will carry the Circum-Martian Dust Monitor (CMDM) which is a newly dev…
Organic matter in interstellar dust lost at the approach to the heliosphere: Exothermic chemical reactions of free radicals ignited by the Sun
Hiroshi Kimura, Frank Postberg, Nicolas Altobelli +1
Aims. We tackle the conundrums of organic materials missing from interstellar dust when measured inside the Solar System, while undoubtedly existing in the local interstellar cloud…
Helios spacecraft data revisited: Detection of cometary meteoroid trails by in-situ dust impacts
Harald Krüger, Peter Strub, Max Sommer +5
Cometary meteoroid trails exist in the vicinity of comets, forming fine structure of the interplanetary dust cloud. The trails consist predominantly of cometary particles with size…
