Supernovae are considered as prime sources of dust in space. Observations of local
supernovae over the past couple of decades have detected the presence of dust in …

Silica grains are ubiquitous in both circumstellar media and rocky bodies and are vital to
cosmic chemical processes, such as surface-catalyzed reactions and lunar water …

We study the formation of molecules and dust clusters in the ejecta of solar metallicity, Type
II-P supernovae (SNe) using a chemical kinetic approach. We follow the evolution of …

Dust particles, ubiquitous throughout the Universe, continuously evolve in processes closely
entangled with the stellar life cycle. Dust nucleates in outflows of dying stars and is heavily …

Reactions of SiO molecules have been postulated to initiate efficient formation of silicate
dust particles in outflows around dying (AGB) stars. Both OH radicals and H2O molecules …

We present a universal method for the large-scale prediction of the atomic structure of
clusters. Our algorithm performs the joint evolutionary search for all clusters in a given area …

This paper reports on computational studies of gas-phase reactions of SiO and Si2O2. The
oxidation of SiO can initiate efficient formation of silica or silicate dust particles in a wide …

Silicon monoxide (SiO) is a structurally complex compound exhibiting differentiated oxide-
rich and silicon-rich nano-phases at length scales covering nanoclusters to the bulk …

The formation of grains in the interstellar medium, ie, at low temperature, has been proposed
as a possibility to solve the lifetime problem of cosmic dust. This process lacks a firm …

To explain observations of abundant circumstellar dust and high stellar wind velocity, most
models simply postulate the efficient nucleation and growth of silicate dust particles. Here …
