Different degrees of nitrogen and carbon depletion in the warm molecular layers of protoplanetary disks
Kenji Furuya, Seokho Lee, Hideko Nomura
Observations have revealed that the elemental abundances of carbon and oxygen in the warm molecular layers of some protoplanetary disks are depleted compared to those is the inters…
Detection of HC18O+ in a protoplanetary disk: exploring oxygen isotope fractionation of CO
Kenji Furuya, Takashi Tsukagoshi, Chunhua Qi +4
The oxygen isotope fractionation scenario, which has been developed to explain the oxygen isotope anomaly in the solar system materials, predicts that CO gas is depleted in 18O in…
TIMES II: Investigating the Relation Between Turbulence and Star-forming Environments in Molecular Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Neal J. Evans +14
We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by a…
Evidence of Accretion Burst: The Viscously Heated Inner Disk of the Embedded Protostar IRAS 16316-1540
Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee +5
Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to thei…
TIMES I: a Systematic Observation in Multiple Molecular Lines Toward the Orion A and Ophiuchus Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Yunhee Choi +16
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the 10 lines of CO, CO, HCN, HCO, and NH and the…
High Spatial Resolution Observations of Molecular Lines towards the Protoplanetary Disk around TW Hya with ALMA
Hideko Nomura, Takashi Tsukagoshi, Ryohei Kawabe +9
We present molecular line observations of 13CO and C18O J=3-2, CN N = 3 - 2, and CS J=7-6 lines in the protoplanetary disk around TW Hya at a high spatial resolution of ~9 au (angu…
