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.

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.

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.

MUPUS insertion device for the Rosetta mission
Journal of Telecommunications and Information Technology, 2023 An original mechanical device designed to insert a penetrator into a cometary nucleus in an almost gravityfree environment is described. The device comprises a hammer and a power supply system that stores electrical energy in a capacitor.
