Effect of Dust Size on the Near-Infrared Spectra (1.0-5.0 m) of Brown Dwarf Atmospheres
Satoko Sorahana, Hiroshi Kobayashi, Kyoko K. Tanaka
In this study, we demonstrate the dependence of atmospheric dust size on the near-infrared spectra of ten L dwarfs, and constrain the sizes of dust grains in each L dwarf atmospher…
Nano Dust in Space and Astrophysics
Ingrid Mann, Aigen Li, Kyoko Tanaka
We summarize the Focus Meeting (FM10) "Nano Dust in Space and Astrophysics" held in Vienna, Austria on 28-29 August 2018 during the 30th General Assembly of the International Astro…
Pure iron grains are rare in the universe
Yuki Kimura, Kyoko K. Tanaka, Takaya Nozawa +2
The abundant forms in which the major elements in the universe exist have been determined from numerous astronomical observations and meteoritic analyses. Iron (Fe) is an exception…
Homogeneous SPC/E water nucleation in large molecular dynamics simulations
R. Angelil, J. Diemand, K. Tanaka +1
We perform direct large molecular dynamics simulations of homogeneous SPC/E water nucleation, using up to molecules. Our large system sizes allow us to measure e…
Simple improvements to classical bubble nucleation models
Kyoko K. Tanaka, Hidekazu Tanaka, Raymond Angélil +1
We revisit classical nucleation theory (CNT) for the homogeneous bubble nucleation rate and improve the classical formula using a new prefactor in the nucleation rate. Most of the…
Bubble Evolution and Properties in Homogeneous Nucleation Simulations
Raymond Angélil, Jürg Diemand, Kyoko Tanaka +1
We analyze the properties of naturally formed nano-bubbles in Lennard-Jones molecular dynamics simulations of liquid-to-vapor nucleation in the boiling and the cavitation regimes.…
Direct Simulations of Homogeneous Bubble Nucleation: Agreement with CNT and no Local Hot Spots
Jürg Diemand, Raymond Angélil, Kyoko K. Tanaka +1
We present results from direct, large-scale molecular dynamics (MD) simulations of homogeneous bubble (liquid-to-vapor) nucleation. The simulations contain half a billion Lennard-J…
Free energy of cluster formation and a new scaling relation for the nucleation rate
Kyoko K. Tanaka, Jürg Diemand, Raymond Angélil +1
Recent very large molecular dynamics simulations of homogeneous nucleation with Lennard-Jones atoms [Diemand et al. J. Chem. Phys. {\bf 139}, 074309 (2013)] allo…
Molecular Dynamics Simulations of the Nucleation of Water: Determining the Sticking Probability and Formation Energy of a Cluster
Kyoko K. Tanaka, Akio Kawano, Hidekazu Tanaka
We performed molecular dynamics (MD) simulations of the nucleation of water vapor in order to test nucleation theories. Simulations were performed for a wide range of supersaturati…
Properties of Liquid Clusters in Large-scale Molecular Dynamics Nucleation Simulations
Raymond Angélil, Jürg Diemand, Kyoko K. Tanaka +1
We have performed large-scale Lennard-Jones molecular dynamics simulations of homogeneous vapor-to-liquid nucleation, with atoms. This large number allows us to resolve extr…
Large Scale Molecular Dynamics Simulations of Homogeneous Nucleation
Jürg Diemand, Raymond Angélil, Kyoko K. Tanaka +1
We present results from large-scale molecular dynamics (MD) simulations of homogeneous vapor-to-liquid nucleation. The simulations contain between one and eight billion Lennard-Jon…
Low-Temperature Crystallization of Amorphous Silicate in Astrophysical Environments
Kyoko. K. Tanaka, Tetsuo Yamamoto, Hiroshi Kimura
We construct a theoretical model for low-temperature crystallization of amorphous silicate grains induced by exothermic chemical reactions. As a first step, the model is applied to…
