Planet Formation and Panspermia

One of the most exciting perspectives in astrochemistry lies in the part played by molecules in space, since they might have a crucial role in the Earth's chemical evolution and origin of life. Life-related molecules may reach the Earth's surface emb

Theoretical analysis of the atmospheric entry of sub-mm meteoroids of Mg x Ca1−xCO 3 composition

Autor: G. Micca Longo, Savino Longo

Publikováno v: Icarus. 310:194-202

Current models allow to reliably simulate mechanical and thermal phenomena associated with a micrometeor passage through the Earth’s atmosphere. However, these models have rarely been applied to materials other than those most common in meteorites,

Evaluation of CaSO4micrograins in the context of organic matter delivery: thermochemistry and atmospheric entry

Autor: Savino Longo, V. Piccinni, G. Micca Longo

Publikováno v: International Journal of Astrobiology. 18:345-352

In this paper, anhydrous calcium sulphate CaSO4(anhydrite) is considered as a carrier material for organic matter delivery from Space to Earth. Its capability of incorporating important fractions of water, leading to different species like bassanite

Thermal decomposition of MgCO3during the atmospheric entry of micrometeoroids

Autor: Savino Longo, G. Micca Longo

Publikováno v: International Journal of Astrobiology. 16:368-378

In this paper, a first study of the atmospheric entry of carbonate micrometeoroids, in an astrobiological perspective, is performed. Therefore an entry model, which includes two-dimensional dynamics, non-isothermal atmosphere, ablation and radiation

Spherically confined H$_2^+$: $^2\Sigma_g^+$ and $^2\Sigma_u^+$ states

Autor: G Micca Longo, Domenico Giordano, Savino Longo

The molecular ion H$_2^+$ is studied under strong confinement conditions produced by a spherical barrier centered in the gravity center of the molecule. Results for the potential curves are obtained by diffusion Monte Carlo methods for the ground sta
