Early Planet Formation in Embedded Disks (eDisk). XVIII. Indication of a possible spiral structure in the dust-continuum emission of the protostellar disk around IRAS 16544-1604 in CB 68

Sanemichi Z. Takahashi, Shigehisa Takakuwa, Ryosuke Nakanishi +11

We performed numerical simulations along with radiative transfer calculations to reproduce an intriguing asymmetric shoulder feature in the dust-continuum emission of the protostel…

Impact of Turbulent Magnetic Fields on Disk Formation and Fragmentation in First Star Formation

Kenji Eric Sadanari, Kazuyuki Omukai, Kazuyuki Sugimura +2

Recent cosmological hydrodynamic simulations have suggested that the first stars in the universe often form as binary or multiple systems. However, previous studies typically overl…

Metallicity Dependence of Molecular Cloud Hierarchical Structure at Early Evolutionary Stages

Masato I. N. Kobayashi, Kazunari Iwasaki, Kengo Tomida +3

The formation of molecular clouds out of HI gas is the first step toward star formation. Its metallicity dependence plays a key role to determine star formation through the cosmic…

Non-ideal magnetohydrodynamic simulations of the first star formation: the effect of ambipolar diffusion

Kenji Eric Sadanari, Kazuyuki Omukai, Kazuyuki Sugimura +2

In the present-day universe, magnetic fields play such essential roles in star formation as angular momentum transport and outflow driving, which control circumstellar disc formati…

Nature of supersonic turbulence and density distribution function in the multiphase interstellar medium

Masato I. N. Kobayashi, Tsuyoshi Inoue, Kengo Tomida +2

Supersonic flows in the interstellar medium (ISM) are believed to be a key driver of the molecular cloud formation and evolution. Among molecular clouds' properties, the ratio betw…
