Effects from different grades of stickiness between icy and silicate particles on carbon depletion in protoplanetary disks
Tamami Okamoto, Shigeru Ida
Earth and other rocky bodies in the inner Solar System are significantly depleted in carbon compared to the Sun and interstellar medium (ISM) dust. Observations indicate that over…
Oxygen Isotope Exchange Between Dust Aggregates and Ambient Nebular Gas
Sota Arakawa, Daiki Yamamoto, Lily Ishizaki +2
Meteorites and their components exhibit a diverse range of oxygen isotope compositions, and the isotopic exchange timescale between dust grains and ambient gas is a key parameter f…
Effective reaction temperatures of irreversible dust chemical reactions in a protoplanetary disk
Lily Ishizaki, Shogo Tachibana, Tamami Okamoto +2
Dust particles in protoplanetary disks experience various chemical reactions under different physicochemical conditions through their accretion and diffusion, which results in the…
Monte Carlo Simulation of Dust Particles in a Protoplanetary Disk: Crystalline to Amorphous Silicate Ratio in Comets
Tamami Okamoto, Shigeru Ida
Observationally inferred crystalline abundance in silicates in comets, which should have been formed in the outer region of a protoplanetary disk, is relatively high (~ 10-60%), al…
