Submillimeter emission associated with candidate protoplanets
Andrea Isella, Myriam Benisty, Richard Teague +4
We present the discovery of a spatially unresolved source of sub-millimeter continuum emission ( m) associated with a young planet, PDS 70 c, recently detected in H em…
How do T Tauri stars accrete
Lee Hartmann, Jaehan Bae
We conjecture that observed protoplanetary disc accretion rates may be explained with low viscosities which could be the result of hydrodynamic turbulence. We show that viscosities…
How do stars gain their mass? A JCMT/SCUBA-2 Transient Survey of Protostars in Nearby Star Forming Regions
Gregory J. Herczeg, Doug Johnstone, Steve Mairs +55
Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accreti…
On the formation of multiple concentric rings and gaps in protoplanetary disks
Jaehan Bae, Zhaohuan Zhu, Lee Hartmann
As spiral waves driven by a planet in a gaseous disk steepen into a shock, they deposit angular momentum, opening a gap in the disk. This has been well studied using both linear th…
Planetary Signatures in the SAO 206462 (HD 135344B) Disk: A Spiral Arm Passing Through Vortex?
Jaehan Bae, Zhaohuan Zhu, Lee Hartmann
The disk surrounding SAO 206462, an 8 Myr-old Herbig Ae star, has recently been reported to exhibit spiral arms, an asymmetric dust continuum, and a dust-depleted inner cavity. By…
Are protoplanetary disks born with vortices? -- Rossby wave instability driven by protostellar infall
Jaehan Bae, Lee Hartmann, Zhaohuan Zhu
We carry out two-fluid, two-dimensional global hydrodynamic simulations to test whether protostellar infall can trigger Rossby wave instability (RWI) in protoplanetry disks. Our re…
