A likely flyby of binary protostar Z CMa caught in action
Ruobing Dong, Hauyu Baobab Liu, Nicolas Cuello +16
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations…
Determining dispersal mechanisms of protoplanetary disks using accretion and wind mass loss rates
Yasuhiro Hasegawa, Thomas J. Haworth, Keri Hoadley +6
Understanding the origin of accretion and dispersal of protoplanetary disks is fundamental for investigating planet formation. Recent numerical simulations show that launching wind…
Keck/OSIRIS Pa high-contrast imaging and updated constraints on PDS~70b
Taichi Uyama, Chen Xie, Yuhiko Aoyama +11
We present a high-contrast imaging search for Pa line emission from protoplanets in the PDS~70 system with Keck/OSIRIS integral field spectroscopy. We applied the high-resolutio…
The architecture of multi-planet systems as a tracer of their formation mechanisms
Udit Arora, Yasuhiro Hasegawa
Exoplanets observed by the {\it Kepler} telescope exhibit a bi-modal, radius distribution, which is known as the radius gap. We explore an origin of the radius gap, focusing on mul…
Formation of rims around chondrules via porous aggregate accretion
Yuji Matsumoto, Yasuhiro Hasegawa, Nozomi Matsuda +1
Chondrules are often surrounded by fine-grained rims or igneous rims. The properties of these rims reflect their formation histories. While the formation of fine-grained rims is mo…
ALMA Observations of the Asymmetric Dust Disk around DM Tau
Jun Hashimoto, Takayuki Muto, Ruobing Dong +5
We report an analysis of the dust disk around DM~Tau, newly observed with the Atacama Large Millimeter/submillimeter Array (ALMA) at 1.3 mm. The ALMA observations with high sensiti…
