From inter-filamentary gas to filaments and hubs: gas flows in the Mon R2 hub-filament system
Jihye Hwang, Doris Arzoumanian, Yoshito Shimajiri +5
Hub-filament systems (HFSs) play an important role in the formation of massive stars and star clusters. Although the velocity structures along dense filaments have been studied, th…
An Origin of Radially Aligned Filaments in Hub-Filament Systems
Shingo Nozaki, Shu-ichiro Inutsuka
Recent observations have identified hub-filament systems (HFSs) as the primary formation sites of massive stars and star clusters. Some HFSs are characterized by multiple filaments…
Self-supervised Synthetic Pretraining for Inference of Stellar Mass Embedded in Dense Gas
Keiya Hirashima, Shingo Nozaki, Naoto Harada
Stellar mass is a fundamental quantity that determines the properties and evolution of stars. However, estimating stellar masses in star-forming regions is challenging because youn…
How External Medium outside Prestellar Cores Affects Protostellar Growth: Variations in Accretion Rate and Evolution of Disks and Outflows
Shingo Nozaki, Masahiro N. Machida
We investigate how the external medium surrounding prestellar cores affects the star formation process by conducting three-dimensional resistive magnetohydrodynamic simulations. Th…
Extended and Compact Ortho-HD Structures Close to the Moment of Star-Formation: Evidence from ALMA-ACA Observations in Taurus
Kazuki Tokuda, Kenji Furuya, Naofumi Fukaya +8
Observing and characterizing pre- and protostellar cores in the earliest and densest stages of star formation is challenging due to their short timescales and high densities, limit…
Tracking Star-Forming Cores as Mass Reservoirs in Clustered and Isolated Regions Using Numerical Passive Tracer Particles
Shingo Nozaki, Hajime Fukushima, Kazuki Tokuda +1
Understanding the physical properties of star-forming cores as mass reservoirs for protostars, and the impact of turbulence, is crucial in star formation studies. We implemented pa…
Internal 1000 AU-scale Structures of the R CrA Cluster-forming Cloud -- I: Filamentary Structures
Kengo Tachihara, Naofumi Fukaya, Kazuki Tokuda +17
We report on ALMA ACA observations of a high-density region of the Corona Australis cloud forming a young star cluster, and the results of resolving internal structures. In additio…
Discovery of Asymmetric Spike-like Structures of the 10 au Disk around the Very Low-luminosity Protostar Embedded in the Taurus Dense Core MC 27/L1521F with ALMA
Kazuki Tokuda, Naoto Harada, Mitsuki Omura +10
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations have revealed an increasing number of compact protostellar disks with radii of less than a few tens of astro…
An ALMA-resolved view of 7000 au Protostellar Gas Ring around the Class I source CrA-IRS 2 as a possible sign of magnetic flux advection
Kazuki Tokuda, Naofumi Fukaya, Kengo Tachihara +5
Transferring a significant fraction of the magnetic flux from a dense cloud core is essential in the star formation process. A ring-like structure produced by magnetic flux loss ha…
