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…
Characterizing CO Fourth Positive Emission in Young Circumstellar Disks
Rebecca Schindhelm, Kevin France, Eric Burgh +5
Carbon Monoxide is a commonly used IR/sub-mm tracer of gas in protoplanetary disks. We present an analysis of ultraviolet CO emission in {HST}-COS spectra for 12 Classical T Tauri…
