This is the first of a series three Papers devoted to study halo substructure in hierarchical cosmologies by means CUSP formalism. In present Paper we derive properties subhaloes and diffuse dark matter (dDM) accreted onto haloes their progenitors. Specifically, relate dDM at any time inter-halo medium real Universe or cosmological simulation with corresponding free-streaming mass resolution ma...

The LITHOPROBE seismic reflection project on Vancouver Island was designed to study the large-scale structure of several accreted terranes exposed on the island and to determine the geometry and structural characteristics of the subducting Juan de Fuca plate. In this paper, we interpret two LITHOPROBE profiles from southernmost Vancouver Island that were shot across three important terrane-boun...

White dwarfs with metal-polluted atmospheres have been studied widely in the context of accretion rocky debris from evolved planetary systems. One open question is geometry and how material arrives mixes white dwarf surface layers. Using 3D radiation-hydrodynamics code CO$^5$BOLD, we present first transport coefficients degenerate star which describe advection-diffusion a passive scalar across ...

Neutron stars formed in Type II supernovae are likely to be initially obscured by late-time fallback. Although much of the late-time fallback is quickly accreted via neutrino cooling, some material remains on the neutron star, forming an atmosphere which slowly accretes through photon emission. In this paper, we derive structure equations of the fallback atmosphere and present results of one-di...

One possible scenario for the formation of carbon-enhanced metal-poor stars is the accretion of carbon-rich material from a binary companion which may no longer visible. It is generally assumed that the accreted material remains on the surface of the star and does not mix with the interior until first dredge-up. However, thermohaline mixing should mix the accreted material with the original ste...

Fully cosmological, high-resolution N-body+smooth particle hydrodynamic simulations are used to investigate the chemical abundance trends of stars in simulated stellar halos as a function of their origin. These simulations employ a physically motivated supernova feedback recipe, as well as metal enrichment, metal cooling, and metal diffusion. As presented in an earlier paper, the simulated gala...

The theory of polar magnetic burial in accreting neutron stars predicts that a mountain of accreted material accumulates at the magnetic poles of the star, and that, as the mountain spreads equatorward, it is confined by, and compresses, the equatorial magnetic field. Here, we extend previous, axisymmetric, Grad–Shafranov calculations of the hydromagnetic structure of a magnetic mountain up to ...

Hubble Space Telescope observations of distant clusters have suggested a steep increase in the proportion of S0 galaxies between clusters at high redshifts and similar systems the present-day. It has been proposed that this increase results from the transformation of the morphologies of accreted field galaxies from spirals to S0s. We have simulated the evolution of the morphological mix in clus...

A low-power, non-thermal, ultrasonic deicing system is introduced as a potential deicing system for helicopter rotor blades that are currently being used. In this research effort, ultrasonic actuator disks excite isotropic plates and airfoil-shaped structures that are representative of helicopter leading edge protection caps. The system generates delaminating ultrasonic transverse shear stresse...
