Monte Carlo Models of Comet Dust Tails Observed from the Ground
Universe, 2022 Dust particles leaving the comet nucleus surface are entrained by the gas within the first few nuclear radius distances and are subjected to a complex hydrodynamical environment.

The Planetary Science JournalComet C/2020 F3 (NEOWISE) reached perihelion on 2020 July 3 at 0.29 au and exhibited a highly structured dust tail. Using a simplified Finson–Probstein model, structures such as striae, observed in the tail in images obtained by the Parker Solar Probe ...

Detectability of Dust and Ion Tails of Interstellar Comet 3I/ATLAS by Europa Clipper
Research Notes of the AASAbstract The Europa Clipper spacecraft is located about 1 au downstream from the interstellar comet 3I/ATLAS around its perihelion. Here we model the propagation of pickup ions and cometary dust originating from 3I/ATLAS to examine their detectability by the Europa Clipper spacecraft.

Active Asteroid 311P/PanSTARRS: Rotational Instability as the Origin of its Multitails?
The Astronomical Journal, 2023 The active asteroid 311P/PanSTARRS is one of the two targets of the planned Chinese asteroid exploration mission Tianwen-2. During 2013, 311P experienced several mass-loss events and exhibited multiple comet-like tails. Here we analyze the morphology and

The formation of striated structures in dust tails of comets [PDF]
Astronomical School’s Report, 2012 The mechanism of formation of striae structures in the dust tails of comets is proposed. There are local active areas on the surfaces of comet nucleus. The formation of striae is indebted to the different rate of dust ejection from active areas depending on that they are located on the sunlit or shaded side of the rotating nucleus.

Dusty plasmas: from Saturn’s rings to semiconductor processing devices
Advances in Physics: X, 2021 Dusty plasmas are plasmas containing solid particles in the size range of about 10 nm—10 μm. The particles acquire an electrical charge by collecting electrons and ions from the plasma, or by photo-electron emission if they are exposed to UV radiation ...

Dust tail of the distant comet C/1999 J2 (Skiff) [PDF]
Astronomy & Astrophysics, 2003 CCD observations of comet C/1999 J2 (Skiff) were made at the Pik Terskol Observatory on September 15, 1999. The 2-m telescope equipped with the two-channel focal reducer of the Max-Plank-Institute for Aeronomy was used to study the cometary environment.

The dust tail of Comet Wilson 1987VII
The Astronomical Journal, 1990 The dust and plasma tails of Comet Wilson 1987VII were studied using photographic plates obtained by means of an ESO Schmidt camera. The plates were digitized adopting a square scanning window of 50 microns and properly calibrated by means of calibration wedges. Dust grains of diameters between 10 microns and 5 cm, ejected during the time interval -600

The dust tail of Comet C/1999 T1 McNaught-Hartley [PDF]
Astronomy & Astrophysics, 2003 A numerical method to compute cometary dust tail brightnesses has been developed. The method, analogous in many ways to the inverse Monte Carlo method proposed by Fulle ([CITE]), has been applied to red continuum images of comet C/1999 T1 McNaught-Hartley obtained by Lara et al. ([CITE]). The time and size dependence of the particle terminal velocities,
