Water vapor as a probe of the origin of gas in debris disks
Yasuhiro Hasegawa, Riouhei Nakatani, Isabel Rebollido +5
Debris disks embrace the formation and evolution histories of planetary systems. Recent detections of gas in these disks have received considerable attention, as its origin ties up…
Broadening the Canonical Picture of EUV-Driven Photoevaporation of Accretion Disks
Riouhei Nakatani, Neal J. Turner, Shinsuke Takasao
Photoevaporation driven by hydrogen-ionizing radiation, also known as extreme-ultraviolet (EUV), profoundly shapes the lives of diverse astrophysical objects. Focusing here mainly…
A Primordial Origin for the Gas-Rich Debris Disks Around Intermediate-Mass Stars
Riouhei Nakatani, Neal J. Turner, Yasuhiro Hasegawa +4
While most debris disks consist of dust with little or no gas, a fraction has significant amounts of gas detected via emission lines of CO, ionized carbon, and/or atomic oxygen. Al…
Formation of dust clumps with sub-Jupiter mass and cold shadowed region in gravitationally unstable disk around Class 0/I protostar in L1527 IRS
Satoshi Ohashi, Riouhei Nakatani, Hauyu Baobab Liu +4
We have investigated the protostellar disk around a Class 0/I protostar, L1527 IRS, using multi-wavelength observations of the dust continuum emission at , 2.1, 3.3, and 6.…
