Effects of accretion flow on the chemical structure in the inner regions of protoplanetary disks
H. Nomura, Y. Aikawa, Y. Nakagawa +1
We have studied the dependence of the profiles of molecular abundances and line emission on the accretion flow in the hot ($\ga 100$K) inner region of protoplanetary disks. The gas…
Resolving the chemistry in the disk of TW Hydrae I. Deuterated species
C. Qi, D. J. Wilner, Y. Aikawa +2
We present Submillimeter Array (SMA) observations of several deuterated species in the disk around the classical T Tauri star TW Hydrae at arcsecond scales, including detections of…
Molecular Evolution and Star Formation: From Prestellar Cores to Protostellar Cores
Yuri Aikawa, Valentine Wakelam, Robin T. Garrod +1
We investigate molecular evolution in a star-forming core that is initially a hydrostatic starless core and collapses to form a low-mass protostar. The results of a one-dimensional…
Molecular Evolution in Collapsing Prestellar Cores III: Contraction of A Bonnor-Ebert Sphere
Yuri Aikawa, Eric Herbst, Helen Roberts +1
The gravitational collapse of a spherical cloud core is investigated by numerical calculations. The initial conditions of the core lie close to the critical Bonnor-Ebert sphere wit…
Axi-symmetric models of ultraviolet radiative transfer with applications to circumstellar disk chemistry
Gerd-Jan van Zadelhoff, Yuri Aikawa, M. R. Hogerheijde +1
A new two-dimensional axi-symmetric ultraviolet radiative transfer code is presented, which is used to calculate photodissociation and ionization rates for use in chemistry models…
