Size Distribution of Small Grains in the Inner Zodiacal Cloud
The Planetary Science JournalAbstract The Parker Solar Probe (PSP) spacecraft has transited the innermost regions of the zodiacal cloud and detects impacts to the spacecraft body via its electric field instrument. Multiple dust populations have been proposed to explain the PSP dust impact rates.

Meteoroid Streams Sculpt the Inner Zodiacal Cloud
The Planetary Science JournalAbstract The abundance of dust encountered by Parker Solar Probe in the inner zodiacal cloud exhibits persistent variability of ∼50% on timescales of its ∼100 day orbits. Spatial variations in the zodiacal cloud of ∼105 km, comparable to meteoroid stream cross sections, can be related to temporal variations of ∼100 days that evolve via ...

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.

A Dust Detection Database for the Inner Heliosphere Using the Parker Solar Probe Spacecraft
The Astrophysical Journal Supplement Series, 2023 A database of in situ dust impact detections made by the Parker Solar Probe spacecraft is created to facilitate studies of interplanetary dust dynamics in the inner heliosphere.

Zodiacal Cloud Complexes [PDF]
Earth, Planets and Space, 2014 We discuss some aspects of the study of the Zodiacal cloud based on brightness observations. The discussion of optical properties as well as the spatial distribution of the dust cloud show that the description of the dust cloud as a homogeneous cloud is reasonable for the regions near the Earth orbit, but fails in the description of the dust in the ...

Near-infrared Polarization Charateristics of the Zodiacal Light Observed with DIRBE/COBE
The Astrophysical Journal, 2023 We report near-infrared polarization of the zodiacal light (ZL) measured from space by the Diffuse Infrared Background Experiment (DIRBE) on board the Cosmic Background Explorer in photometric bands centered at 1.25, 2.2, and 3.5 μ m.

Disentangling the main populations of the Zodiacal Cloud from Zodiacal Light observations [PDF]
Earth, Planets and Space, 2014 Photometric surveys of the Zodiacal Light (ZL) already allowed to retrieve features of interplanetary dust space distribution and optical behaviour. Of the brightness “gathering” function dZ = D(α)/m along each line of sight (LOS), (α being the phase angle, m the subsolar distance of the LOS, D) the local scattering coefficient), two approximate values

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 ...

The Astronomical Journal, 2023 The diffuse, unresolved sky provides most of the photons that the Hubble Space Telescope (HST) receives, yet remains poorly understood. The HST Archival Legacy program SKYSURF aims to measure the 0.2–1.6 μ m sky surface brightness (sky-SB) from over 140 ...

Mercury's Exosphere as Seen by BepiColombo/PHEBUS Visible Channels During the First Two Flybys
Journal of Geophysical Research: Planets, Volume 128, Issue 12, December 2023., 2023 Abstract BepiColombo, the ESA/JAXA joint mission performed its first flyby of Mercury on 1 October 2021 and its second on 23 June 2022. PHEBUS observed the exosphere of Mercury during these flybys notably with its visible channels c404 (centered on the potassium emission line at 404 nm) and c422 (centered on the calcium emission line at 422 nm).
