Protoplanetary disks, that are rotating disks of gas and dust surrounding young stars, become the birthplace of planets. However, details of the formation process of these disks remain unclear. In (...more)

Polarization Substructure in the Spiral-dominated HH 111 Disk: Evidence for Grain Growth
In the early phase of star formation, protostellar disks are formed to grow the central protostars into stars. The disks will later evolve into protoplanerary disks to form planets like (...more)
Multiple Misaligned Outflows and Warped Accretion Flows in the Proto-multiple System Per-emb-8 and 55
Multiple Misaligned Outflows and Warped Accretion Flows in the Proto-multiple System Per-emb-8 and 55
Multiple systems are common outcome in the star-forming regions. However, the formation process of multiple system remains unclear due to the complex dynamic. To address this, we analyze the ALMA (...more)

Star formation quenching refers to the process by which galaxies cease forming stars, transitioning from actively star-forming to passive states. Many mechanisms have been proposed to explain star formation quenching. (...more)

Resolved Measurements of the CO-to-H2 Conversion Factor in 37 Nearby Galaxies
The molecular phase of the interstellar medium (ISM) hosts star formation. Measuring its properties, e.g. density and kinematics, is key to understanding star formation and ISM properties. The low-J CO (...more)

Early Planet Formation in Embedded Disks (eDisk). XIV. Flared Dust Distribution and Viscous Accretion Heating of the Disk around R CrA IRS 7B-a
Early Planet Formation in Embedded Disks (eDisk). XIV. Flared Dust Distribution and Viscous Accretion Heating of the Disk around R CrA IRS 7B-a
With the ALMA large program eDisk, we identified hot dust disks around a number of protostars. One of such objects, R Cr A IRS 7B-a, exhibits a peak brightness temperature (...more)
