Kepler-7b: A Transiting Planet with Unusually Low Density
David W. Latham, William J. Borucki, David G. Koch +18
We report the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, Mp = 0.43 Mj, but the radius is f…
Albedo heterogeneity on the surface of (1943) Anteros
Joseph Masiero
We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the Univers…
Identifying Anomalies in Gravitational Lens Time Delays
Arthur B. Congdon, Charles R. Keeton, C. Erik Nordgren
We examine the ability of gravitational lens time delays to reveal complex structure in lens potentials. In Congdon, Keeton & Nordgren (2008), we predicted how the time delay betwe…
Formation and evolution of planetary systems: the impact of high angular resolution optical techniques
Olivier Absil, Dimitri Mawet
The direct images of giant extrasolar planets recently obtained around several main sequence stars represent a major step in the study of planetary systems. These high-dynamic rang…
Fragmentation and Evolution of Molecular Clouds. II: The Effect of Dust Heating
Andrea Urban, Hugo Martel, Neal J. Evans
We investigate the effect of heating by luminosity sources in a simulation of clustered star formation. Our heating method involves a simplified continuum radiative transfer method…
SpeX Spectroscopy of Unresolved Very Low-Mass Binaries. I. Identification of Seventeen Candidate Binaries Straddling the L Dwarf/T Dwarf Transition
Adam J. Burgasser, Kelle L. Cruz, Michael Cushing +5
We report the identification of 17 candidate brown dwarf binaries whose components straddle the L dwarf/T dwarf transition. These sources were culled from a large near-infrared spe…
Recent VLBA/VERA/IVS Tests of General Relativity
E. Fomalont, S. Kopeikin, D. Jones +2
We report on recent VLBA/VERA/IVS observational tests of General Relativity. First, we will summarize the results from the 2005 VLBA experiment that determined gamma with an accura…
The Faint End of the Quasar Luminosity Function at z~4
Eilat Glikman, Milan Bogosavljevic, S. G. Djorgovski +4
We have conducted a spectroscopic survey to find faint quasars (-26.0 < M_{1450} < -22.0) at redshifts z=3.8-5.2 in order to measure the faint end of the quasar luminosity function…
The Vector Vortex Coronagraph: Laboratory Results and First Light at Palomar Observatory
D. Mawet, E. Serabyn, K. Liewer +3
High-contrast coronagraphy will be needed to image and characterize faint extra-solar planetary systems. Coronagraphy is a rapidly evolving field, and many enhanced alternatives to…
Parallactic Motion for Companion Discovery: An M-Dwarf Orbiting Alcor
Neil Zimmerman, Ben R. Oppenheimer, Sasha Hinkley +16
The A5V star Alcor has an M3-M4 dwarf companion, as evidenced by a novel astrometric technique. Imaging spectroscopy combined with adaptive optics coronagraphy allowed for the dete…
Coupling Photosphere and Corona: Linear and Turbulent Regimes
A. Verdini, R. Grappin, M. Velli
In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction eff…
Turbulence, Energy Transfers and Reconnection in Compressible Coronal Heating Field-line Tangling Models
R. B. Dahlburg, A. F. Rappazzo, M. Velli
MHD turbulence has long been proposed as a mechanism for the heating of coronal loops in the framework of the Parker scenario for coronal heating. So far most of the studies have f…
Checking Stability Of Planet Orbits In Multiple-planet Systems
F. Malbet, J. Catanzarite, M. Shao +1
The SIM Lite mission will undertake several planet surveys. One of them, the Deep Planet Survey, is designed to detect Earth-mass exoplanets in the habitable zones of nearby main s…
Optical Vectorial Vortex Coronagraphs using Liquid Crystal Polymers: theory, manufacturing and laboratory demonstration
D. Mawet, E. Serabyn, K. Liewer +4
In this paper, after briefly reviewing the theory of vectorial vortices, we describe our technological approach to generating the necessary phase helix, and report results obtained…
Application of XFaster power spectrum and likelihood estimator to Planck
G. Rocha, C. R. Contaldi, J. R. Bond +1
We develop the XFaster Cosmic Microwave Background (CMB) temperature and polarization anisotropy power spectrum and likelihood technique for the Planck CMB satellite mission. We gi…
Naturally-phasematched second harmonic generation in a whispering gallery mode resonator
J. U. Fürst, D. V. Strekalov, D. Elser +4
We demonstrate for the first time natural phase matching for optical frequency doubling in a high-Q whispering gallery mode resonator made of Lithium Niobate. A conversion efficien…
The Architecture of the Cassini Division
M. M. Hedman, P. D. Nicholson, K. H. Baines +6
The Cassini Division in Saturn's rings contains a series of eight named gaps, three of which contain dense ringlets. Observations of stellar occultations by the Visual and Infrared…
Abell 370 revisited: refurbished Hubble imaging of the first strong lensing cluster
Johan Richard, Jean-Paul Kneib, Marceau Limousin +2
We present a strong lensing analysis of the galaxy cluster Abell 370 (z=0.375) based on the recent multicolor ACS images obtained as part of the Early Release Observation (ERO) tha…
A turbulence-driven model for heating and acceleration of the fast wind in coronal holes
A. Verdini, M. Velli, W. H. Matthaeus +2
A model is presented for generation of fast solar wind in coronal holes, relying on heating that is dominated by turbulent dissipation of MHD fluctuations transported upwards in th…
