A machine learning potential for simulating infrared spectra of nanosilicate clusters
Zeyuan Tang, Stefan T. Bromley, Bjørk Hammer
The use of machine learning (ML) in chemical physics has enabled the construction of interatomic potentials having the accuracy of ab initio methods and a computational cost compar…
Bottom-up dust nucleation theory in oxygen-rich evolved stars I. Aluminium oxide clusters
David Gobrecht, John M. C. Plane, Stefan T. Bromley +3
Aluminum oxide (alumina, AlO) is a promising candidate as a primary dust condensate in the atmospheres of oxygen-rich evolved stars. Therefore, alumina \textit{seed} pa…
A global optimisation study of the low-lying isomers of the alumina octomer (AlO)
David Gobrecht, Leen Decin, Sergio Cristallo +1
We employ the Monte-Carlo Basin-Hopping (MC-BH) global optimisation technique with inter- atomic pair potentials to generate low-energy candidates of stoichiometric alumina octomer…
Nucleation of small silicon carbide dust clusters in AGB stars
David Gobrecht, Sergio Cristallo, Luciano Piersanti +1
Silicon carbide (SiC) grains are a major dust component in carbon-rich AGB stars. The formation pathways of these grains are, however, not fully understood.\ We calculate ground st…
Dust formation in the oxygen-rich AGB star IK Tau
D. Gobrecht, I. Cherchneff, A. Sarangi +2
We model the synthesis of molecules and dust in the inner wind of the oxygen-rich Mira-type star IK Tau, by considering the effects of periodic shocks induced by the stellar pulsat…
