Grain growth in protoplanetary disks in the Upper Scorpius revealed by millimeter-wave spectral indices
Tau Bito, Akimasa Kataoka, Takahiro Ueda +3
The measurement of dust size from millimeter-wavelength spectra provides direct constraints on grain growth in protoplanetary disks. The spectral indices between 0.88 mm and 2.9 mm…
Multi dust species inner rim in magnetized protoplanetary disks
Mario Flock, Ondřej Chrenko, Takahiro Ueda +3
The inner regions of protoplanetary disks, within ten astronomical units, are where terrestrial planets are born. By developing a new class of multi-dust radiative magnetized inner…
Predictions of dust continuum observations of circumplanetary disks with ngVLA: A case study of PDS 70 c
Yuhito Shibaike, Takahiro Ueda, Misato Fukagawa
A gas giant forms a small gas disk called a "circumplanetary disk (CPD)" around the planet during its gas accretion process. The small gas disk contains dust particles like those i…
Multi-Wavelength Dust Characterization of the HL Tau Disk and Implications for Planet Formation
Takahiro Ueda, Sean M. Andrews, Carlos Carrasco-González +4
We present a comprehensive analysis of the HL Tau dust disk by modeling its intensity profiles across six wavelengths (0.45 to 7.9 mm) with a resolution of 0.05 arcsec ( au)…
Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus
Caleb Painter, Sean M. Andrews, Claire J. Chandler +9
We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…
SMA and NOEMA reveal asymmetric sub-structure in the protoplanetary disk of IRAS23077+6707
Joshua B. Lovell, Leon Trapman, Kristina Monsch +5
We present high-resolution data of IRAS 23077+6707 (`Dracula's Chivito') with the Submillimeter Array (SMA at 1.33 mm/225.5 GHz) and the Northern Extended Millimeter Array (NOEMA a…
Thermally driven spontaneous dust accumulation in the inner regions of protoplanetary disks
Ryo Kato, Takahiro Ueda, Satoshi Okuzumi
In protoplanetary disks, the formation of planetesimals via streaming and/or gravitational instabilities requires regions with a locally enhanced dust-to-gas mass ratio. Convention…
