ON the DUST ENVIRONMENT of MAIN-BELT COMET 313 P/Gibbs [PDF]

open access: yes, 2015
peer reviewedWe present observations carried out using the 10.4 m Gran Telescopio Canarias and an interpretative model of the dust environment of activated asteroid 313 P/Gibbs.

Mechanistic Study of Platelet Membrane‐Coated Resveratrol Nanosystem in Mitochondrial Dysfunction and Endothelial Senescence During Atherosclerotic Lesion Development via FOXM1 Activation

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Schematic diagram of the mechanism by which PM@RSV NPs alleviate AS via FOXM1 activation. ABSTRACT Atherosclerosis (AS) is closely linked to endothelial cell (EC) senescence and mitochondrial dysfunction, which impair vascular repair. Resveratrol (RSV) has antioxidant, anti‐inflammatory, and pro‐angiogenic effects, but its clinical use is restricted by

Two dust populations of particle fragments in the striated tail of Comet MRKOS 1957 V

open access: yesThe Astronomical Journal, 1982
The striated tail of Comet Mrkos 1957 V is investigated. The formation and motions of the striae are described by the same particle-fragmentation model that has been successfully applied to Comet West. Two new kinds of striae are discovered, one made of absorbing particles and the other of essentially nonabsorbing ones.

The wind-sock theory of comet tails [PDF]

open access: yes, 1976
A method is reported for calculating the shapes of ionic comet tails that use the magnetic field along the tail to channel the tail plasma. The local momentum field in the solar wind determines magnetic field line locations along the tail.

A Monte Carlo approach to the analysis of the dust tail of comet P/Halley

open access: yesIcarus, 1992
Abstract A quantitative analysis of three wide-field photographs of Comet P/Halley obtained between 3 and 6 May 1986 has been carried out. The digitally processed maps were used as input for the Monte Carlo approach to interpreting cometary dust tails.

Dust in comet 103P/Hartley 2 coma by imaging polarimetry

open access: yes, 2012
Comet Hartley 2 dust was observed 21 days before perihelion and eight days after, at the time of the EPOXI mission. The scattered light by the dust was studied by a polarimetric imaging technique in different wavelengths (visible and near infrared)

Comet Tail Analyzer: A GUI Tool for Finson–Probstein Dust-tail Modeling

open access: yesResearch Notes of the AAS
Abstract I present Comet Tail Analyzer , an open-source Python graphical application for projecting Finson–Probstein syndyne and synchrone grids onto comet images. Operating as a forward-modeling tool, the software computes and overlays dust-particle loci on user-supplied ...
