Hopkins Ultraviolet Telescope Observations of Her X-1 (2009)
Bram Boroson, William P. Blair, Arthur F. Davidsen, S. D. Vrtilek, John Raymond, Knox S. Long, ...
We have obtained a far-ultraviolet spectrum of the X-ray binary Hercules X-1/HZ Herculis using the Hopkins Ultraviolet Telescope aboard the Astro-1 space shuttle mission in 1990 December. This is the...
FUSE Observations of a Full Orbit of Hercules X-1: Signatures of Disk, Star, and Wind (2007)
Boroson, Bram, Vrtilek, Saeqa Dil, Raymond, John C., Still, Martin
We observed an entire 1.7 day orbit of the X-ray binary Hercules X-1 with the Far Ultraviolet Spectroscopic Explorer (FUSE). Changes in the O VI 1032,1037 line profiles through eclipse ingress and...

Stellar Coronal Spectroscopy with the Chandra HETGS (2003)
Huenemoerder, David P., Boroson, Bram, Schulz, Norbert S., Canizares, Claude R., Buzasi, Derek L., Preston, Heather L., ...
Spectroscopy with the Chandra High Energy Transmission Grating Spectrometer provides details on X-ray emission and activity from young and cool stars through resolution of emission lines from a...
Hot Outflowing Gas from the X-ray Binary Hercules X-1 (2001)
Boroson, Bram, Kallman, Tim, Vrtilek, Saeqa Dil
We present a unified picture of outflowing gas from the X-ray binary system Hercules X-1/HZ Herculis. We suggest that the outflowing gas (a wind) causes UV emission seen in mid-eclipse, narrow UV...
Atmospheric reflection during an anomalous low state of Hercules X-1 (2001)
Still, Martin, O'Brien, Kieran, Horne, Keith, Boroson, Bram, Titarchuk, Lev G., Engle, Kimberly, ...
We present RXTE observations of the eclipsing X-ray binary Hercules X-1 during an anomalous low state. Data reduction reveals a light curve over 2.7 orbital cycles remarkably similar to optical and...
RXTE observations of Hercules X-1 during the 1998 July short high state (2001)
Still, Martin, O'Brien, Kieran, Horne, Keith, Hudson, Danny, Boroson, Bram, Vrtilek, Saeqa Dil, ...
We present RXTE monitoring of the eclipsing X-ray binary Hercules X-1 conducted over the short high state of 1998 July. This was one of the last major short high states before the source entered an...
RXTE Observations of Hercules X-1 During the July 1998 Short-high State (2001)
Still, Martin, O'Brien, Kieran, Horne, Keith, Hudson, Danny, Boroson, Bram, Vrtilek, Saeqa Dil, ...
We present RXTE monitoring of the eclipsing X-ray binary Hercules X-1 conducted over the short-high state of July 1998. This was one of the last major short-high states before the source entered an...

We present RXTE observations of the eclipsing X-ray binary Hercules X-1 conducted during an anomalous low state. Data reduction reveals a light curve over 2.7 orbital cycles remarkably similar to...
An Interstellar Conduction Front Within a Wolf-Rayet Ring Nebula Observed with the GHRS (1996)
Boroson, Bram, McCray, Richard, Clark, Christina Oelfke, Slavin, Jonathan, Mac Low, Mordecai-Mark, Chu, You-Hua, ...
With the High Resolution Spectrograph aboard the Hubble Space Telescope we obtained high signal-to-noise (S/N > 200 - 600 per 17 km/s resolution element) spectra of narrow absorption lines toward the...
