On the Origin of Faint Intracluster Starlight in Coma
Vladimir Korchagin, Toshio Tsuchiya, Shoken M. Miyama
Using N-body numerical simulations, we examine possible mechanisms for the origin of the intracluster starlight features recently discovered in the Coma cluster of galaxies. We sho…
Magnetorotational Instability in Protoplanetary Disks. II. Ionization State and Unstable Regions
Takayoshi Sano, Shoken M. Miyama, Toyoharu Umebayashi +1
We investigate where in protoplanetary disks magnetorotational instability operates, which can cause angular momentum transport in the disks. We investigate the spatial distributio…
Global Spiral Modes in NGC 1566: Observations and Theory
V. Korchagin, N. Kikuchi, S. M. Miyama +2
We present an observational and theoretical study of the spiral structure in galaxy NGC 1566. A digitized image of NGC 1566 in I-band was used for measurements of the radial depend…
