Heating in an Extended Accretion Disk Corona along the Z-Pattern in Cyg X-2
N. S. Schulz, D. P. Huenemoerder, L. Ji +3
We observed at very high spectral resolution the prototype Z-source Cyg x-2 twice along its entire X-ray spectral variation pattern. In this preliminary analysis we find an extende…
Photometric properties of resolved and unresolved magnetic elements
Serena Criscuoli, Mark Rast
We investigate the photometric signature of magnetic flux tubes in the solar photosphere. We developed two dimensional, static numerical models of isolated and clustered magnetic f…
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
S. Johnston, R. Taylor, M. Bailes +47
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
Cluster Abell 520: a perspective based on member galaxies. A cluster forming at the crossing of three filaments?
M. Girardi, R. Barrena, W. Boschin +1
The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still debated. An interesting case is the rich, merging cluster Abell 5…
A dynamical perspective on additional planets in 55 Cancri
Sean N. Raymond, Rory Barnes, Noel Gorelick
Five planets are known to orbit the star 55 Cancri. The recently-discovered planet f at 0.78 AU (Fischer et al. 2008) is located at the inner edge of a previously-identified stable…
Ubiquitous Water Masers in Nearby Star-Forming Galaxies
Jeremy Darling, Crystal Brogan, Kelsey Johnson
We report the detection of water maser emission from four nearby galaxies hosting ultradense HII (UDHII) regions, He 2-10, the Antennae galaxies (NGC 4038/4039), NGC 4214, and NGC…
A New FUSE Survey of Interstellar HD
Theodore P. Snow, Teresa L. Ross, Joshua D. Destree +5
We have used archival FUSE data to complete a survey of interstellar HD in 41 lines of sight with a wide range of extinctions. This follow up to an earlier survey was made to furth…
Photoevaporation of Protoplanetary Disks
Z. Balog, G. H. Rieke, J. Muzerolle +4
We present HST/NICMOS Paschen alpha images and low and high resolution IRS spectra of photoevaporating disk-tail systems originally detected at 24 micron near O stars. We find no P…
Tides and the Evolution of Planetary Habitability
Rory Barnes, Sean N. Raymond, Brian Jackson +1
Tides raised on a planet by its host star's gravity can reduce a planet's orbital semi-major axis and eccentricity. This effect is only relevant for planets orbiting very close to…
Sunyaev-Zel'dovich Effect Observations of the Bullet Cluster (1E 0657-56) with APEX-SZ
N. W. Halverson, T. Lanting, P. A. R. Ade +33
We present observations of the Sunyaev-Zel'dovich effect (SZE) in the Bullet cluster (1E 0657--56) using the APEX-SZ instrument at 150 GHz with a resolution of 1 arcmin. The main r…
The effect of photo-ionization on the cooling rates of enriched, astrophysical plasmas
Robert P. C. Wiersma, Joop Schaye, Britton D. Smith
Radiative cooling is central to a wide range of astrophysical problems. Despite its importance, cooling rates are generally computed using very restrictive assumptions, such as col…
Calibration and flight performance of the long-slit imaging dual order spectrograph
Roxana E. Lupu, Stephan R. McCandliss, Brian Fleming +3
We present a preliminary calibration and flight performance of the Long-Slit Imaging Dual Order Spectrograph (LIDOS), a rocket-borne instrument with a large dynamic range in the 90…
Mg I emission lines at 12 and 18 micrometer in K giants
J. O. Sundqvist, N. Ryde, G. M. Harper +2
The solar Mg I emission lines at 12 micrometer have already been observed and analyzed well. Previous modeling attempts for other stars have, however, been made only for Procyon an…
Cosmological Shocks in Adaptive Mesh Refinement Simulations and the Acceleration of Cosmic Rays
Samuel W. Skillman, Brian W. O'Shea, Eric J. Hallman +2
We present new results characterizing cosmological shocks within adaptive mesh refinement N-Body/hydrodynamic simulations that are used to predict non-thermal components of large-s…
The Mass Distribution and Lifetime of Prestellar Cores in Perseus, Serpens, and Ophiuchus
Melissa L. Enoch, Neal J. Evans, Anneila I. Sargent +3
We present an unbiased census of starless cores in Perseus, Serpens, and Ophiuchus, assembled by comparing large-scale Bolocam 1.1 mm continuum emission maps with Spitzer c2d surve…
From Shock Breakout to Peak and Beyond: Extensive Panchromatic Observations of the Type Ib Supernova 2008D associated with Swift X-ray Transient 080109
Maryam Modjaz, W. Li, N. Butler +38
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis…
`Tail-end' Bondi-Hoyle accretion in young star clusters: Implications for disks, planets, and stars
Henry B. Throop, John Bally
Young stars orbiting in the gravitational potential well of forming star clusters pass through the cluster's dense molecular gas and can experience Bondi-Hoyle accretion from reser…
IR Contamination in Galactic X-Ray Novae
Mark T. Reynolds, Paul J. Callanan, Edward L. Robinson +1
The most widely used means of measuring the mass of black holes in Galactic binaries - specifically the X-ray novae - involves both radial velocity measurements of the secondary st…
