Interplanetary dust delivery of water to the atmospheres of Pluto and Triton

, 2018
Context. Both Pluto and Triton possess thin, N2-dominated atmospheres controlled by sublimation of surface ices. Aims. We aim to constrain the influx and ablation of interplanetary dust grains into the atmospheres of both Pluto and Triton in order to

The Spheroidal Analog Method for Modeling Irregular Porous Aggregates

The Astrophysical Journal
It is shown that the optical properties of an irregular porous grain with effective radius a _eff  ≲ 3 λ (where λ is the wavelength) can be well approximated by a “spheroidal analog”: a spheroid with appropriate axial ratio and size, with a dielectric ...

Reactive Molecular Dynamics Simulations of Micrometeoroid Bombardment for Space Weathering of Asteroid (162173) Ryugu

The Astrophysical Journal
Remote sensing observations by Hayabusa2 and laboratory measurements have revealed that the phyllosilicates on asteroid (162173) Ryugu are dehydrated/dehydroxylated due to space weathering.

Link between interplanetary & cometary dust: Polarimetric observations and space studies with Rosetta & Eye-Sat

, 2014
International audienceIntensity and linear polarization observations of the solar light scattered by interplanetary dust, the so-called zodiacal light, provide information on properties of the dust particles, such as their spatial density, local changes,

Combined micro-infrared (IR) and micro-raman measurements on stratospheric interplanetary dust particles

, 2007
In preparation for the Stardust sample analyses, we performed combined micro-IR/micro-Raman measurements on five Interplanetary Dust Particles (IDPs) that were characterized by Field Emission Scanning Electron Microscope analyses.

Magnesium Isotopic Composition of Interplanetary Dust Particles

, 1979
The magnesium isotopic composition of some extraterrestrial dust particles has been measured. The particles are believed to be samples of interplanetary dust, a significant fraction of which originated from the disaggregation of comets and may contain ...

Kuiper Belt Dust Grains as a Source of Interplanetary Dust Particles

, 1996
The recent discovery of the so-called Kuiper belt objects has prompted the idea that these objects produce dust grains that may contribute significantly to the interplanetary dust population.
