High-resolution Ultraviolet Radiation Fields of Classical T Tauri Stars
Kevin France, Rebecca Schindhelm, Edwin Bergin +2
The far-ultraviolet (FUV; 912--1700 Å) radiation field from accreting central stars in Classical T Tauri systems influences the disk chemistry during the period of giant planet for…
Hot Gas Lines in T Tauri Stars
David R. Ardila, Gregory J. Herczeg, Scott G. Gregory +20
For Classical T Tauri Stars (CTTSs), the resonance lines of N V, Si IV, and C IV, as well as the He II 1640 A line, act as diagnostics of the accretion process. Here we assemble a…
Probing the Inner Regions of Protoplanetary Disks with CO Absorption Line Spectroscopy
Matthew McJunkin, Kevin France, Eric B. Burgh +4
Carbon monoxide (CO) is the most commonly used tracer of molecular gas in the inner regions of protoplanetary disks. CO can be used to constrain the excitation and structure of the…
Lyman alpha dominance of the Classical T Tauri FUV Radiation Field
Rebecca Schindhelm, Kevin France, Gregory Herczeg +6
Far-ultraviolet (FUV) radiation plays an important role in determining chemical abundances in protoplanetary disks. HI Lyman alpha is suspected to be the dominant component of the…
From Protoplanetary Disks to Extrasolar Planets: Understanding the Life Cycle of Circumstellar Gas with Ultraviolet Spectroscopy
Kevin France, Matthew Beasley, David R. Ardila +20
Few scientific discoveries have captured the public imagination like the explosion of exoplanetary science during the past two decades. This work has fundamentally changed our pict…
A Hubble Space Telescope Survey of H2 Emission in the Circumstellar Environments of Young Stars
Kevin France, Rebecca Schindhelm, Gregory J. Herczeg +8
The formation timescale and final architecture of exoplanetary systems are closely related to the properties of the molecular disks from which they form. Observations of the spatia…
