The formation of astrophysical Mg-rich silicate dust
Christopher Mauney, Davide Lazzati
We present new results for ground-state candidate energies of Mg-rich olivine (MRO) clusters and use the binding energies of these clusters to determine their nucleation rates in s…
Conservation of Angular Momentum in the Fast Multipole Method
Oleg Korobkin, Hyun Lim, Irina Sagert +5
Smoothed particle hydrodynamics (SPH) is positioned as having ideal conservation properties. When properly implemented, conservation of total mass, energy, and both linear and angu…
Formation and properties of astrophysical carbonaceous dust. I: ab-initio calculations of the configuration and binding energies of small carbon clusters
Christopher Mauney, Marco Buongiorno Nardelli, Davide Lazzati
The binding energies of n < 100 carbon clusters are calculated using the ab-initio density functional theory code Quantum Espresso. Carbon cluster geometries are determined using s…
Formation and properties of astrophysical carbonaceous dust
Christopher Mauney, Davide Lazzati
The classical theory of grain nucleation suffers from both theoretical and predictive deficiencies. We strive to alleviate these deficiencies in our understanding of dust formation…
