ALMA 2D super-resolution imaging survey of Ophiuchus Class I/flat spectrum/II disks. II. Statistical analysis of stellar and disk properties
Ayumu Shoshi, Masayuki Yamaguchi, Takayuki Muto +5
We present a statistical study of stellar and dust disk properties for young stellar objects in the Ophiuchus star-forming region. Building on our previous paper (Shoshi et al. 202…
A Hybrid Origin for the Multiple Ring-Gap Structures in the Large Protoplanetary Disk V1094 Sco: A Low-Mass Planet and Secular Gravitational Instability
Masayuki Yamaguchi, Masahiro N. Machida, Ryosuke T. Tominaga +7
High spatial resolution observations reveal that some protoplanetary disks host multiple ring-gap pairs at large stellocentric radii, yet their physical origin remains unsettled. W…
ALMA Band 9 CO(6--5) Reveals a Warm Ring Structure Associated with the Embedded Protostar in the Cold Dense Core MC 27/L1521F
Kazuki Tokuda, Mitsuki Omura, Naoto Harada +9
Infall and outflows, coupled with magnetic fields, rapidly structure the gas around newborn protostars. Shocks from interacting components encode the temperature and density distri…
Ring-Gap Structures in the Class I Circumstellar Disk of CrA IRS 2 Associated with Magnetic Flux-Driven Bubble
Ayumu Shoshi, Masayuki Yamaguchi, Mitsuki Omura +4
Recent ALMA observations with 0''.1 resolution reveal characteristic substructures in circumstellar disks around young Class I sources, providing clues to the early stages of morph…
ALMA High-resolution Observation for the Transitional Disk around IRAS 04125+2902
Ayumu Shoshi, Takayuki Muto, Quincy Bosschaart +5
Recently, the youngest transiting planet was discovered around the T Tauri star, IRAS 04125+2902, in the Taurus-Auriga star-forming region. This system is crucial for understanding…
ALMA 2D Super-resolution Imaging Survey of Ophiuchus Class I/Flat Spectrum/II Disks -- I: Discovery of New Disk Substructures
Ayumu Shoshi, Masayuki Yamaguchi, Takayuki Muto +4
This study focuses on Class I, Flat Spectrum (FS), and Class II disks in the Ophiuchus molecular cloud, a nearby active star-forming region with numerous young stellar objects (YSO…
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…
Ring Gap Structure around Class I Protostar WL 17
Ayumu Shoshi, Naoto Harada, Kazuki Tokuda +7
WL 17 is a Class I object and was considered to have a ring-hole structure. We analyzed the structure around WL 17 to investigate the detailed properties of WL 17. We used ALMA arc…
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…
