Absence of Significant Cool Disks in Young Stellar Objects Exhibiting Repetitive Optical Outbursts
Hauyu Baobab Liu, Roberto Galván-Madrid, Eduard I. Vorobyov +10
We report Submillimeter Array (SMA) 1.3 mm high angular resolution observations towards the four EXor type outbursting young stellar objects (YSOs) VY Tau, V1118 Ori, V1143 Ori, an…
Planetary System Formation in Protoplanetary Disk around HL Tauri
Eiji Akiyama, Yasuhiro Hasegawa, Masahiko Hayashi +1
We re-process the Atacama Large Millimeter/Submillimeter Array (ALMA) long-baseline science verification data taken toward HL Tauri. As shown by the previous work, we confirm that…
Chondrule Formation via Impact Jetting Triggered by Planetary Accretion
Yasuhiro Hasegawa, Shigeru Wakita, Yuji Matsumoto +1
Chondrules are one of the most primitive elements that can serve as a fundamental clue as to the origin of our Solar system. We investigate a formation scenario of chondrules that…
Viscous Instability Triggered by Layered Accretion in Protoplanetary Disks
Yasuhiro Hasegawa, Taku Takeuchi
Layered accretion is one of the inevitable ingredients in protoplanetary disks when disk turbulence is excited by magnetorotational instabilities (MRIs). In the accretion, disk sur…
Probing the Physical Conditions of Supernova Ejecta with the Measured Sizes of Presolar Al2O3 Grains
Takaya Nozawa, Shigeru Wakita, Yasuhiro Hasegawa +1
A few particles of presolar Al2O3 grains with sizes above 0.5 mum are believed to have been produced in the ejecta of core-collapse supernovae (SNe). In order to clarify the format…
