Leaky Dust Traps in Planet-embedded Protoplanetary Disks
The Astrophysical JournalFrom the survival of dust disks for a few Myr to the establishment of chemical dichotomy, dust traps are expected to play a pivotal role in sculpting protoplanetary disks and the early planet formation process.

The Astrophysical JournalJWST has enabled the detection of the ultraviolet (UV) continuum of galaxies at z > 10, revealing extremely blue, potentially dust-free galaxies. However, interpreting UV spectra is complicated by the well-known degeneracy between stellar ages, dust ...

Shoulder of Dust Rings Formed by Planet–Disk Interactions
The Astrophysical JournalRecent analyses of millimeter-wavelength protoplanetary disk observations have revealed several emission excesses on the previously identified dust rings, referred to as dust shoulders.

Distances to Recent Near-Earth Supernovae from Geological and Lunar 60Fe
The Astrophysical JournalNear-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive ^60 Fe pointing to a supernova at 3 Myr ago, as well as the recent discovery

Inside-out Planet Formation. VIII. Onset of Planet Formation and the Transition Disk Phase
The Astrophysical JournalInside-out planet formation (IOPF) is a theory of in situ formation via pebble accretion of close-in Earth to super-Earth mass planets at the pressure maximum associated with the dead zone inner boundary (DZIB), whose location is set initially by thermal

The Astrophysical JournalA near-infrared (NIR) excess has been discovered in the emission of the representative fast blue optical transient (FBOT) AT 2018cow. It was suggested that this NIR excess could be emitted by the dust surrounding the source and thus could provide a probe

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2
The Astrophysical JournalDiffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...
