Recent laboratory astrophysics publications delve into various aspects of astrophysical processes and phenomena. A study explores the optical constants of different types of water ice analogues in the terahertz-infrared range. Another research paper investigates the elemental and isotopic compositions of asteroid Bennu and meteorites from the outer Solar System.
Scientists also study the bulk and isotopic abundances of hydrogen in carbonaceous chondrites. The mechanical properties of salty ice powders are examined as analogues for Europa's erupted ice. Vapor pressure measurements of low-temperature hydrocarbon ices are conducted. The impact of specific chemical reactions on interstellar cloud chemistry is assessed.
Laboratory experiments investigate the behavior of molecules in dark interstellar clouds. Researchers analyze the interaction between nitrogen and aromatic hydrocarbons in atmospheric chemistry. The prebiotic chemistry of Titan is explored, focusing on nucleobases, ribose, and fatty acids. Titan's haze analogs' properties are examined under varying formation pressures.
The physical properties of Titan's haze are studied. Organics' adhesion force on Titan's surface is evaluated under low temperatures. Electron irradiation effects on methanol ices are discussed, with implications for Europa's surface chemistry. Laboratory studies explore the formation and behavior of the benzene cation from acetylene in helium nanodroplets.
The chemical evolution of methane ices is assessed under cosmic ray analogs processing. The dominant chemical reactions contributing to the formation and consumption of specific compounds in methane ices are identified.
