A Search for Meteoroid Streams and Their Sources in the Near-Sun Zodiacal Dust Cloud
The Astrophysical JournalThe structure and dynamics of the zodiacal cloud close to the Sun may be significantly influenced by the interaction between a background quasihomogeneous zodiacal cloud and discrete meteoroid streams associated with small bodies like comets and ...

Formation, Structure, and Detectability of the Geminids Meteoroid Stream
The 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.

Investigation of Dust Grains by Optical Tweezers for Space Applications
The 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

The orbital distribution of radar-detected meteoroids of the Solar system dust cloud [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 The radar meteoroid orbit data set obtained from the AMOR facility in Christchurch, New Zealand (longitude 172 ◦ 39 E, latitude 43 ◦ 34 S) between 1995 May and 1999 October contains ∼5 × 10 5 high-quality meteor records. The system was very sensitive compared with previous surveys, with a limiting radio magnitude of +14 corresponding to a 3 × 10 ...

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 ...

A Comparison of Geminid Models with the PSP/WISPR-observed Phaethon Dust Trail
The Astrophysical JournalWhite-light observations from the Wide-Field Imager for Parker Solar Probe (WISPR) instrument on NASA’s Parker Solar Probe recently revealed the presence of a narrow, dense dust trail close to the orbit of asteroid 3200 Phaethon. Although Geminid related,

How Long-lived Grains Dominate the Shape of the Zodiacal Cloud
The Planetary Science JournalGrain–grain collisions shape the three-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least understood sink of zodiacal dust grains. For the first time, we combine
