We study the formation of molecular precursors to dust in the ejecta of Population III supernovae (Pop. III SNe) using a chemical kinetic approach to follow the evolution of small dust cluster abundances from day 100 to day 1000 after explosion. Our work focuses on zero-metallicity 20 M sun and 170 M sun progenitors, and we consider fully macroscopically mixed and unmixed ejecta. The dust precursors comprise molecular chains, rings, and small clusters of chemical composition relevant to the… 
THE CHEMICALLY CONTROLLED SYNTHESIS OF DUST IN TYPE II-P SUPERNOVAE
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 molecules and small
Condensation of dust in the ejecta of Type II-P supernovae
Aims: We study the production of dust in Type II-P supernova by coupling the gas-phase chemistry to the dust nucleation and condensation phases. We consider two supernova progenitor masses with
The interplay between chemistry and nucleation in the formation of carbonaceous dust in supernova ejecta
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 of dust formation in
Molecules and dust in the ejecta of Type II-P supernovae
Abstract We study the formation of molecules and dust clusters in the ejecta of solar metallicity, Type II-P supernovae using a chemical kinetic approach and follow the evolution of molecules and
Molecules and dust in Cassiopeia A - I. Synthesis in the supernova phase and processing by the reverse shock in the clumpy remnant
Aims: We study the chemistry of the Type IIb supernova ejecta that led to the Cas A supernova remnant to assess the chemical type and quantity of dust that forms and evolves in the remnant phase. We
Formation of Dust in the Ejecta of Type Ia Supernovae
We investigate the formation of dust grains in the ejecta of Type Ia supernovae (SNe Ia), adopting the carbon-deflagration W7 model. In the calculations of dust formation, we apply the nucleation and

TLDR
A kinetic model to describe the formation of gas-phase precursors from Ca, Mg, Fe, SiO and TiO in an outflow cooling from 1500 to 1000 K shows that more than 10−13 CN per H nucleus will be produced when the outflow temperature is still well above 1000‬K, sufficient to explain the observed number density of grains in circumstellar dust shells.
Molecules and dust in Cassiopeia A - II. Dust sputtering and diagnosis of supernova dust survival in remnants
We study the dust evolution in the supernova remnant Cassiopeia A. We follow the processing of dust grains that formed in the Type II-b supernova ejecta by modelling the sputtering of grains. The
The metal and dust yields of the first massive stars
We quantify the role of Population (Pop) III core-collapse supernovae (SNe) as the first cosmic dust polluters. Starting from a homogeneous set of stellar progenitors with masses in the range [13 -
Dust formation and evolution in the ejecta of core-collapse supernovae
Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter
