Redshifted Absorption at He I 10830 as a Probe of the Accretion Geometry of T Tauri Stars
William Fischer, John Kwan, Suzan Edwards +1
We probe the geometry of magnetospheric accretion in classical T Tauri stars by modeling red absorption at He I 10830 via scattering of the stellar and veiling continua. Under the…
Modeling T Tauri Winds from He I 10830 Profiles
John Kwan, Suzan Edwards, William Fischer
The high opacity of He I 10830 makes it an exceptionally sensitive probe of the inner wind geometry of accreting T Tauri stars. In this line blueshifted absorption below the contin…
Non-Equilibrium Ionization Model for Stellar Cluster Winds and its Application
Li Ji, Q. Daniel Wang, John Kwan
We have developed a self-consistent physical model for super stellar cluster winds based on combining a 1-D steady-state adiabatic wind solution and a non-equilibrium ionization ca…
Probing T Tauri Accretion and Outflow with 1 Micron Spectroscopy
Suzan Edwards, William Fischer, Lynne Hillenbrand +1
In a high dispersion 1 micron survey of 39 classical T Tauri stars veiling is detected in 80%, and He I 10830 and Pgamma line emission in 97% of the stars. On average, the 1 micron…
He I 10830 as a Probe of Winds in Accreting Young Stars
S. Edwards, W. Fischer, J. Kwan +2
He I 10830 profiles acquired with Keck's NIRSPEC for 6 young low mass stars with high disk accretion rates (AS 353A, DG Tau, DL Tau, DR Tau, HL Tau and SVS 13) provide new insight…
