The Cosmic Origins Spectrograph: On-Orbit Instrument Performance
S. Osterman, J. Green, C. Froning +31
The Cosmic Origins Spectrograph (COS) was installed in the Hubble Space Telescope in May, 2009 as part of Servicing Mission 4 to provide high sensitivity, medium and low resolution…
Ultraviolet and X-ray Variability of the Seyfert 1.5 Galaxy Markarian 817
Lisa M. Winter, Charles Danforth, Ranjan Vasudevan +9
We present an investigation of the ultraviolet and X-ray spectra of the Seyfert 1.5 galaxy Markarian 817. The ultraviolet analysis includes two recent observations taken with the C…
Cosmic Origins Spectrograph Detection of Ne VIII Tracing Warm - Hot Gas Towards PKS 0405-123
Anand Narayanan, Blair D. Savage, Bart P. Wakker +7
We report on the detection of Ne VIII in the HST/Cosmic Origins Spectrograph spectrum of the intervening absorption system at z = 0.495096 towards PKS 0405-123. The high S/N COS sp…
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…
Metals in the Exosphere of the Highly Irradiated Planet WASP-12b
L. Fossati, C. A. Haswell, C. S. Froning +17
We present near-UV transmission spectroscopy of the highly irradiated transiting exoplanet WASP-12b, obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope. Th…
Near-Infrared Spectroscopy of Low Mass X-ray Binaries : Accretion Disk Contamination and Compact Object Mass Determination in V404 Cyg and Cen X-4
Juthika Khargharia, Cynthia S. Froning, Edward L. Robinson
We present near-infrared (NIR) broadband (0.80--2.42 m) spectroscopy of two low mass X-ray binaries: V404 Cyg and Cen X-4. One important parameter required in the determination…
