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…
Confirmation of IGR J01363+6610 as a Be X-ray binary with very low quiescent X-ray luminosity
John A. Tomsick, Craig Heinke, Jules Halpern +4
The field containing the candidate High Mass X-ray Binary IGR J01363+6610 was observed by XMM-Newton on 2009 July 31 for 28 ks. A Be star was previously suggested as the possible c…
Suzaku observes weak flares from IGR J17391-3021 representing a common low-activity state in this SFXT
A. Bodaghee, J. A. Tomsick, J. Rodriguez +4
We present an analysis of a 37-ks observation of the supergiant fast X-ray transient (SFXT) IGR J17391-3021 (=XTE J1739-302) gathered with Suzaku. The source evolved from quiescenc…
The Exoplanet Orbit Database
Jason T Wright, Onsi Fakhouri, Geoffrey W. Marcy +8
We present a database of well determined orbital parameters of exoplanets. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from r…
Imaging Spectroscopy of a White-Light Solar Flare
J. C. Martinez Oliveros, S. Couvidat, J. Schou +4
We report observations of a white-light solar flare (SOL2010-06-12T00:57, M2.0) observed by the Helioseismic Magnetic Imager (HMI) on the Solar Dynamics Observatory (SDO) and the R…
RXTE and XMM observations of intermediate polar candidates
O. W. Butters, A. J. Norton, K. Mukai +1
Aims. To determine the credentials of nine candidate intermediate polars in order to confirm whether or not they are magnetic cataclysmic variables. Methods. Frequency analysis of…
The geometry of the filamentary environment of galaxy clusters
Yookyung Noh, J. D. Cohn
We construct a filament catalogue using an extension of the halo based filament finder of Zhang et al.(2009), in a 250 Mpc/h side N-body simulation, and study the properties of fil…
System Geometries and Transit / Eclipse Probabilities
Kaspar von Braun, Stephen R. Kane, Suvrath Mahadevan +3
Transiting exoplanets provide access to data to study the mass-radius relation and internal structure of extrasolar planets. Long-period transiting planets allow insight into plane…
Search for Gravitational Wave Bursts from Six Magnetars
J. Abadie, B. P. Abbott, R. Abbott +765
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…
The NASA-UC Eta-Earth Program: III. A Super-Earth orbiting HD 97658 and a Neptune-mass planet orbiting Gl 785
Andrew W. Howard, John Asher Johnson, Geoffrey W. Marcy +7
We report the discovery of planets orbiting two bright, nearby early K dwarf stars, HD 97658 and Gl 785. These planets were detected by Keplerian modelling of radial velocities mea…
STEREO and Wind observations of a fast ICME flank triggering a prolonged geomagnetic storm on 5-7 April 2010
Christian Möstl, Manuela Temmer, Tanja Rollett +6
On 5 April 2010 an interplanetary (IP) shock was detected by the Wind spacecraft ahead of Earth, followed by a fast (average speed 650 km/s) IP coronal mass ejection (ICME). During…
Flaring Solar Hale Sector Boundaries
Leif Svalgaard, Iain G. Hannah
Magnetic fields and the occurrence of flares and microflares are strongly concentrated near that portion (the Hale boundary) in each solar hemisphere where the change in magnetic s…
GEANT4 Simulations of Gamma-Ray Emission from Accelerated Particles in Solar Flares
Shichao Tang, David M. Smith
Gamma-ray spectroscopy provides diagnostics of particle acceleration in solar flares, but care must be taken when interpreting the spectra due to effects of the angular distributio…
The Oblique Orbit of the Super-Neptune HAT-P-11b
Joshua N. Winn, John Asher Johnson, Andrew W. Howard +6
We find the orbit of the Neptune-sized exoplanet HAT-P-11b to be highly inclined relative to the equatorial plane of its host star. This conclusion is based on spectroscopic observ…
O vi in the local interstellar medium
M. A. Barstow, D. D. Boyce, B. Y. Welsh +2
We report the results of a search for O VI absorption in the spectra of 80 hot DA white dwarfs observed by the FUSE satellite. We have carried out a detailed analysis of the radial…
Constraining the hard X-ray properties of the quiet Sun with new RHESSI observations
I. G. Hannah, H. S. Hudson, G. J. Hurford +1
We present new RHESSI upper limits in the 3-200 keV energy range for solar hard X-ray emission in the absence of flares and active regions, i.e. the quiet Sun, using data obtained…
