Discovery of Line Pressure Broadening and Direct Constraint on Gas Surface Density in a Protoplanetary Disk
Tomohiro C. Yoshida, Hideko Nomura, Takashi Tsukagoshi +2
The gas surface density profile of protoplanetary disks is one of the most fundamental physical properties to understand planet formation. However, it is challenging to determine t…

A new method for direct measurement of isotopologue ratios in protoplanetary disks: a case study of the CO/CO ratio in the TW Hya disk
Tomohiro C. Yoshida, Hideko Nomura, Kenji Furuya +2
Planetary systems are thought to be born in protoplanetary disks. Isotope ratios are a powerful tool for investigating the material origin and evolution from molecular clouds to pl…
