Supercooled Lennard-Jones Liquids and Glasses: a Kinetic Monte Carlo Approach
Javier Hernandez-Rojas, David J. Wales
A kinetic Monte Carlo (KMC) method is used to study the structural properties and dynamics of a supercooled binary Lennard-Jones liquid around the glass transition temperature. Thi…
Spectroscopic Signatures of Convection in the Spectrum of Procyon. Fundamental Parameters and Iron Abundance
Carlos Allende Prieto, Martin Asplund, Ramon J. Garcia Lopez +1
We have observed the spectrum of Procyon A (F5IV) from 4559 to 5780 A with a S/N of ~ 1e3 and a resolving power of 2e5. We have measured the line bisectors and relative line shifts…
Probability distribution of density fluctuations in the non-linear regime
J. Betancort-Rijo, M. Lopez-Corredoira
We present a general procedure for obtaining the present density fluctuation probability distribution given the statistics of the initial conditions. The main difficulties faced wi…
Analysis of the solar cycle and core rotation using 15 years of Mark-I observations:1984-1999. I. The solar cycle
S. J. Jiménez-Reyes, T. Corbard, P. L. Pallé +2
High quality observations of the low-degree acoustic modes (p-modes) exist for almost two complete solar cycles using the solar spectrophotometer Mark-I, located at the Observatori…
Detection of variable circular polarization in the SW Sex star V795 Herculis
P. Rodriguez-Gil, J. Casares, I. G. Martinez-Pais +1
We report the detection of modulated circular polarization in V795 Her. The degree of polarization increases with wavelength and is modulated with a period of 19.54 min, which is v…
A Fluid Dynamics Calculation of Sputtering from a Cylindrical Thermal Spike
M. M. Jakas, E. M. Bringa, R. E. Johnson
The sputtering yield, Y, from a cylindrical thermal spike is calculated using a two dimensional fluid dynamics model which includes the transport of energy, momentum and mass. The…
