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…
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…
Radiative shocks create environments for dust formation in novae
Andrea M. Derdzinski, Brian D. Metzger, Davide Lazzati
Classical novae commonly show evidence of rapid dust formation within months of the outburst. However, it is unclear how molecules and grains are able to condense within the ejecta…
The interplay between chemistry and nucleation in the formation of carbonaceous dust in supernova ejecta
Davide Lazzati, Alexander Heger
Core-collapse supernovae are considered to be important contributors to the primitive dust enrichment of the interstellar medium in the high-redshift universe. Theoretical models o…
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…
On the effects of microphysical grain properties on the yields of carbonaceous dust from type II SNe
David W. Fallest, Takaya Nozawa, Ken'ichi Nomoto +4
We study the role of the unknown microphysical properties of carbonaceous dust particles in determining the amount and size distribution of carbonaceous dust condensed in type II s…
Thermal fluctuations and nanoscale effects in the nucleation of carbonaceous dust grains
Adam C. Keith, Davide Lazzati
We investigate the role of thermal fluctuations and of the finite number of monomers in small clusters of carbon atoms on the nucleation rate of carbonaceous grains. Thermal fluctu…
