Thermochemical constraints on a primordial-origin of gas-rich debris disks
H. Mitani, W. Ooyama, R. Nakatani +2
Recent observations have revealed gas-rich debris disks around intermediate-mass stars at ages of tens of Myr. The origin of this gas remains unclear: it may be primordial, retaine…

From streamers to stars: overcoming mass loss in protoplanetary disks
W. Ooyama, R. Nakatani, T. Hosokawa +1
Recent high-resolution observations have revealed filamentary accretion flows (``streamers'') in protoplanetary disks older than 1 Myr, suggesting that late-stage interstellar gas…
