Dust Seeding Molecules in a Massive Protostar -- Detection of TiO in Orion Source I
Ziwei E. Zhang, Nami Sakai, Marcelino Agundez +16
We report the first detection of TiO in star-forming regions based on Atacama Large Millimeter/submillimeter Array observations of Orion Source I, a well-characterized massive prot…
Distribution of Chemically-Processed Dust in a Viscously Evolving Protoplanetary Disk: Application to Crystalline Silicates in Comets
Lily Ishizaki, Shogo Tachibana, Shigeru Ida
Dust particles undergo chemical reactions in protoplanetary disks according to their environments, producing compositional diversity in planetary materials. Extraterrestrial record…
Characteristics of natural remanence records in fine-grained particles returned from asteroid Ryugu
Masahiko Sato, Yuki Kimura, Tadahiro Hatakeyama +25
Particles collected from the asteroid Ryugu by the Hayabusa2 spacecraft offer a unique opportunity to investigate the magnetic record of the primitive solar system, as any terrestr…
The Elemental Abundances of Ryugu: Assessment of Chemical Heterogeneities and the Nugget Effect
Tetsuya Yokoyama, Nicolas Dauphas, Ryota Fukai +6
The Hayabusa 2 spacecraft sampled ~5.4 g of asteroid material from the Cb-type asteroid Ryugu. Initial analysis of the Ryugu materials revealed a mineralogical, chemical, and isoto…
