The astrophysical context of collision processes in meteorites
Chondrites are leftover solids from the early evolution of solar protoplanetary disk that never experienced melting since their formation. They comprise unequilibrated assemblages low- and high-temperature components, including volatile-rich, fine-grained matrices, Fe-Ni metal, s
A stochastic droplet collision model with consideration of impact efficiency
A stochastic droplet collision model (Sommerfeld [9]), based on the creation of a fictitious collision partner is described, taking into account impact efficiencies. The model of O’Rourke [5] is considered to predict the outcome of water-droplet collisions, being grazing or coale
Intra-collision Effects in the Collision-broadening of Spectral Line Profiles
Some details of events occurring during collisions that affect the profiles of collision-broadened spectral lines are reviewed. Emphasis is on the impact and quasi-static approximations. Rotational level mixing and collisional propagation are shown to be important processes. The
The collision of particles in granular systemsNikolai
Collisions between granular particles are irreversible processes which cause dissipation of mechanical energy by fragmentation or heating of the colliders. The knowledge of these phenomena is essential for the understanding of the behaviour of complex systems of granular particle
Research of the Influences of Input Parameters on the Result of Vehicles Collision Simulation
Vehicle collisions are complex processes which are determined by a large number of different parameters. The development of computer programs for simulation has made the collision analysis and reconstruction procedure easier, as well as the possibility to realise the influences o
Non-LTE Balmer line formation in late-type spectra: Effects of atomic processes involving hydrogen atoms
Context. The wings of Balmer lines are often used as effective temperature diagnostics for late-type (F, G, K) stars under the assumption they form in local thermodynamic equilibrium (LTE). Aims. Our goal is to investigate the non-LTE excitation and ionisation of hydrogen and the
Antiproton – Hydrogen Atom Collision at Intermediate
ion–atom collision processes is important in atomic physics. It helps us fundamentally understand particle interactions and the corresponding dynamics for applications in many subfields, such as fusion sciences, astrophysics, and material sciences. Furthermore, it presents an int
An atomistic investigation of FIB process damage on diamond
Focused Ion Beam (FIB) is one of the important machining techniques to fabricate diamond sensors/detectors used for drug analysis, chemical analysis and bio-sensing applications. In-depth understanding of the high energy collision process and the residual damage induced along the
Classical simulations and particle production in heavy-ion collisions
One of the most important predictions of lattice QCD is the existence of a transition from ordinary hadronic matter, where quarks and gluons are confined, to a quark–gluon plasma at high temperatures. Current estimates are that this transition takes place at Tc ∼ 150 − 170 MeV, a
