Five Planets Orbiting 55 Cancri
Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler +9
We report 18 years of Doppler shift measurements of a nearby star, 55 Cancri, that exhibit strong evidence for five orbiting planets. The four previously reported planets are stron…
Spitzer 24-micron Time-Series Observations of the Eclipsing M-dwarf Binary GU Bootis
Kaspar von Braun, Gerard T. van Belle, David R. Ciardi +3
We present a set of {\it Spitzer} 24m MIPS time series observations of the M-dwarf eclipsing binary star GU Boötis. Our data cover three secondary eclipses of the system: two co…
Complex Organic Materials in the Circumstellar Disk of HR 4796A
J. H. Debes, A. J. Weinberger, G. Schneider
We combine HST/NICMOS imaging photometry of the HR 4796A disk at previously unobserved wavelengths between 1.71-2.22\micron with reprocessed archival observations to produce a meas…
GRB070125: The First Long-Duration Gamma-Ray Burst in a Halo Environment
S. B. Cenko, D. B. Fox, B. E. Penprase +15
We present the discovery and high signal-to-noise spectroscopic observations of the optical afterglow of the long-duration gamma-ray burst GRB070125. Unlike all previously observed…
Sources of zodiacal dust
S. I. Ipatov
Fractions of asteroidal particles, particles originating beyond Jupiter's orbit (including trans-Neptunian particles), and cometary particles originating inside Jupiter's orbit amo…
Dynamical Zodiacal Cloud Models Constrained by High Resolution Spectroscopy of the Zodiacal Light (Icarus, in press)
Sergei I. Ipatov, Alexander S. Kutyrev, Greg J. Madsen +3
The simulated Doppler shifts of the solar Mg I Fraunhofer line produced by scattering on the solar light by asteroidal, cometary, and trans-Neptunian dust particles are compared wi…
Observational Tests of Planet Formation Models
A. Sozzetti, G. Torres, D. W. Latham +8
We summarize the results of two experiments to address important issues related to the correlation between planet frequencies and properties and the metallicity of the hosts. Our r…
An Overdensity of i-dropouts Among A Population of Excess Field Objects in the Virgo Cluster
Haojing Yan, Nimish Hathi, Rogier Windhorst
Using a set of deep imaging data obtained by the ACS on the HST shortly after its deployment, Yan, Windhorst & Cohen (2003) found a large number of F775W-band dropouts (i-dropouts)…
Debris Disks Around Nearby Stars with Circumstellar Gas
Aki Roberge, Alycia J. Weinberger
We conducted a survey for infrared excess emission from 16 nearby main sequence shell stars using the Multiband Imaging Photometer for Spitzer (MIPS) on the Spitzer Space Telescope…
Mid-Infrared Spectroscopy of Lensed Galaxies at 1<z<3: The Nature of Sources Near the MIPS Confusion Limit
J. R. Rigby, D. Marcillac, E. Egami +10
We present Spitzer/IRS mid-infrared spectra for 15 gravitationally lensed, 24 micron--selected galaxies, and combine the results with 4 additional very faint galaxies with IRS spec…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Optical/Infrared Observations of the Anomalous X-ray Pulsar 1E 1048.1-5937 During Its 2007 X-Ray Flare
Z. Wang, C. Bassa, V. M. Kaspi +2
We report on optical and infrared observations of the anomalous X-ray pulsar (AXP) 1E 1048.1-5937, made during its ongoing X-ray flare which started in 2007 March. We detected the…
The SEGUE Stellar Parameter Pipeline. III. Comparison with High-Resolution Spectroscopy of SDSS/SEGUE Field Stars
C. Allende Prieto, T. Sivarani, T. C. Beers +14
We report high-resolution spectroscopy of 125 field stars previously observed as part of the Sloan Digital Sky Survey and its program for Galactic studies, the Sloan Extension for…
The initial-final mass relationship from white dwarfs in common proper motion pairs
S. Catalan, J. Isern, E. Garcia-Berro +3
The initial-final mass relationship of white dwarfs, which is poorly constrained, is of paramount importance for different aspects in modern astrophysics. From an observational per…
HAT-P-4b: A metal-rich low-density transiting hot Jupiter
G. Kovacs, G. A. Bakos, G. Torres +14
We describe the discovery of HAT-P-4b, a low-density extrasolar planet transiting BD+36 2593, a V = 11.2 mag slightly evolved metal-rich late F star. The planet's orbital period is…
The Survival Rate of Ejected Terrestrial Planets with Moons
J. H. Debes, S. Sigurdsson
During planet formation, a gas giant will interact with smaller protoplanets that stray within its sphere of gravitational influence. We investigate the outcome of interactions bet…
An m sin i = 24 Earth Mass Planetary Companion To The Nearby M Dwarf GJ 176
