Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]
, 1992 The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

CO2: A Small Ubiquitous Molecule With a Lot of Astrochemical Debate Attached
Frontiers in Astronomy and Space Sciences, 2020 Water, carbon monoxide and carbon dioxide are the most abundant molecules in the condensed phase of interstellar dust grains. Water is formed by hydrogenation of oxygen species adsorbed on the surface of dust grains, while carbon monoxide is formed by ...

Mechanical Properties of Cometary Surfaces
Universe, 2022 Mechanical properties, in particular, strength (tensile, shear, compressive) and porosity, are important parameters for understanding the evolution and activity of comets. However, they are notoriously difficult to measure.

Small-body encounters using solar sail propulsion [PDF]
, 2004 Cometary Rendezvous and Flybys have large V requirements, which impose almost unattainable, and sometimes prohibitive, demands on the propellant budget of conventional, chemical propulsion.

Activity of Comets Constrains the Chemistry and Structure of the Protoplanetary Disk
Universe, 2022 Recent data of molecular clouds and protoplanetary disks constrain the composition and structure of the disk and planetesimals. Laboratory experiments suggest that dust accretion in disks stops at pebble sizes. Sublimation and recondensation of water ice

Application of the regularization method to differential equations of comets' motion
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009 Regularization method for differential equation of comets' motion is used. Numerical integration of the equation of motion of 10 short-period comets during the period of 1800 to 2204 with the use of osculating elements of the large planets is done.

Chemical Convection and Stratification in the Earth's Outer Core
Frontiers in Earth Science, 2019 Convection in the Earth's outer core is driven by buoyancy sources of both thermal and compositional origin. The thermal and compositional molecular diffusivities differ by several orders of magnitude, which can affect the dynamics in various ways.
