Dust enrichment and grain growth in a smooth disk around the DG Tau protostar revealed by ALMA triple bands frequency observations
Satoshi Ohashi, Munetake Momose, Akimasa Kataoka +10
Characterizing the physical properties of dust grains in a protoplanetary disk is critical to comprehending the planet formation process. Our study presents ALMA high-resolution ob…
Primordial or Secondary? Testing models of debris disk gas with ALMA
Gianni Cataldi, Yuri Aikawa, Kazunari Iwasaki +13
The origin and evolution of gas in debris disks is still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed. So far, obs…
A Constraint on the Amount of Hydrogen from the CO Chemistry in Debris Disks
Kazunari Iwasaki, Hiroshi Kobayashi, Aya E. Higuchi +1
The faint CO gases in debris disks are easily dissolved into C by UV irradiation, while CO can be reformed via reactions with hydrogen. The abundance ratio of C/CO could thus be a…
