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…
The Far-Ultraviolet "Continuum" in Protoplanetary Disk Systems II: CO Fourth Positive Emission and Absorption
Kevin France, Rebecca Schindhelm, Eric B. Burgh +21
We exploit the high sensitivity and moderate spectral resolution of the -Cosmic Origins Spectrograph to detect far-ultraviolet spectral features of carbon monoxide (CO) presen…
Observations of Mass Loss from the Transiting Exoplanet HD 209458b
Jeffrey L. Linsky, Hao Yang, Kevin France +4
Using the new Cosmic Origins Spectrograph (COS) on the {\it Hubble Space Telescope (HST)}, we obtained moderate-resolution, high signal/noise ultraviolet spectra of HD 209458 and i…
Searching for Far-Ultraviolet Auroral/Dayglow Emission from HD209458b
Kevin France, John T. Stocke, Hao Yang +5
We present recent observations from the HST-Cosmic Origins Spectrograph aimed at characterizing the auroral emission from the extrasolar planet HD209458b. We obtained medium-resolu…
