Mutual Orbits and Masses of Six Transneptunian Binaries
W. M. Grundy, K. S. Noll, M. W. Buie +3
We present Hubble Space Telescope observations of six binary transneptunian systems: 2000 QL251, 2003 TJ58, 2001 XR254, 1999 OJ4, (134860) 2000 OJ67, and 2004 PB108. The mutual orb…
High Albedos of Low Inclination Classical Kuiper Belt Objects
M. J. Brucker, W. M. Grundy, J. A. Stansberry +4
We present observations of thermal emission from fifteen transneptunian objects (TNOs) made using the Spitzer Space Telescope. Thirteen of the targets are members of the Classical…
Reconnectionless CME eruption: putting the Aly-Sturrock conjecture to rest
L. A. Rachmeler, C. E. DeForest, C. C. Kankelborg
We demonstrate that magnetic reconnection is not necessary to initiate fast CMEs. The Aly-Sturrock conjecture states that the magnetic energy of a given force free boundary field i…
The Correlated Colors of Transneptunian Binaries
S. D. Benecchi, K. S. Noll, W. M. Grundy +3
We report resolved photometry of the primary and secondary components of 23 transneptunian binaries obtained with the Hubble Space Telescope. V-I colors of the components range fro…
Did Saturn's rings form during the Late Heavy Bombardment ?
Sebastien Charnoz, Alessandro Morbidelli, Luke H. Dones +1
The origin of Saturn\' s massive ring system is still unknown. Two popular scenarios - the tidal splitting of passing comets and the collisional destruction of a satellite - rely o…
On a Scattered-Disk Origin for the 2003 El61 Collisional Family - an Example of the Importance of Collisions on the Dynamics of Small Bodies
Harold F. Levison, Morbidelli Alessandro, David Vokrouhlicky +1
The recent discovery of the 2003EL61 collisional family in the Kuiper belt (Brown et al., 2007) is surprising because the formation of such a family is a highly improbable event in…
Solar Coronal Structures and Stray Light in TRACE
C. E. DeForest, P. C. H. Martens, M. J. Wills-Davey
Using the 2004 Venus transit of the Sun to constrain a semi-empirical point-spread function for the TRACE EUV solar telescope, we have measured the effect of stray light in that te…
The TEXES Survey For H2 Emission From Protoplanetary Disks
M. A. Bitner, M. J. Richter, J. H. Lacy +9
We report the results of a search for pure rotational molecular hydrogen emission from the circumstellar environments of young stellar objects with disks using the Texas Echelon Cr…
The Distribution of Basaltic Asteroids in the Main Belt
Nicholas A. Moskovitz, Robert Jedicke, Eric Gaidos +4
We present the observational results of a survey designed to target and detect asteroids whose colors are similar to those of Vesta family members and thus may be considered as can…
POLAR Investigation of the Sun - POLARIS
T. Appourchaux, P. Liewer, M. Watt +34
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the S…
Photometry and spectroscopy of GRB 060526: A detailed study of the afterglow and host galaxy of a z=3.2 gamma-ray burst
C. C. Thöne, D. A. Kann, G. Jóhannesson +58
Aims: With this paper we want to investigate the highly variable afterglow light curve and environment of gamma-ray burst (GRB) 060526 at . Methods: We present one of the…
(42355) Typhon-Echidna: Scheduling Observations for Binary Orbit Determination
W. M. Grundy, K. S. Noll, J. Virtanen +6
We describe a strategy for scheduling astrometric observations to minimize the number required to determine the mutual orbits of binary transneptunian systems. The method is illust…
Main Belt Binary Asteroidal Systems With Eccentric Mutual Orbits
F. Marchis, P. Descamps, J. Berthier +5
Using 8m-10m class telescopes and their Adaptive Optics (AO) systems, we conducted a long-term adaptive optics campaign initiated in 2003 focusing on four binary asteroid systems:…
`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…
[Ne II] Observations of Gas Motions in Compact and Ultracompact H II Regions
Qingfeng Zhu, John H. Lacy, Daniel T. Jaffe +2
We present high spatial and spectral resolution observations of sixteen Galactic compact and ultracompact H II regions in the [Ne II] 12.8 microns fine structure line. The small th…
Redetermination of the space weathering rate using spectra of Iannini asteroid family members
Mark Willman, Robert Jedicke, David Nesvorný +3
Rewriting a shorter abstract.
Reappraising Transition Region Line Widths in light of Recent Alfvén Wave Discoveries
Scott W. McIntosh, Bart De Pontieu, Theodore D. Tarbell
We provide a new interpretation of ultraviolet transition region emission line widths observed by the SUMER instrument on the Solar and Heliospheric Observatory (SOHO). This invest…
Origin of the Structure of the Kuiper Belt during a Dynamical Instability in the Orbits of Uranus and Neptune
Harold F. Levison, Alessandro Morbidelli, Christa Van Laerhoven +2
We explore the origin and orbital evolution of the Kuiper belt in the framework of a recent model of the dynamical evolution of the giant planets, sometimes known as the Nice model…
CME Propagation Characteristics from Radio Observations
S. Pohjolainen, L. van Driel-Gesztelyi, J. L. Culhane +2
We explore the relationship among three coronal mass ejections (CMEs), observed on 28 October 2003, 7 November 2004, and 20 January 2005, the type II burst-associated shock waves i…
On connecting the dynamics of the chromosphere and transition region with Hinode SOT and EIS
Viggo H. Hansteen, Bart De Pontieu, Mats Carlsson +14
We use coordinated Hinode SOT/EIS observations that include high-resolution magnetograms, chromospheric and TR imaging and TR/coronal spectra in a first test to study how the dynam…
