First Terrestrial Soft X-ray Auroral Observation by The Chandra X-ray Observatory

Anil Bhardwaj, G. Randall Gladstone, Ronald F. Elsner +6

Northern auroral regions of Earth were imaged with energetic photons in the 0.1-10 keV range using the High-Resolution Camera (HRC-I) aboard the Chandra X-ray Observatory at 10 epo…

A study of Jupiter's aurorae with XMM-Newton

G. Branduardi-Raymont, A. Bhardwaj, R. F. Elsner +6

We present a detailed analysis of Jupiter's X-ray (0.2-10 keV) auroral emissions as observed by XMM-Newton in Nov. 2003 and compare it with that of an Apr. 2003 observation. We dis…

On the Size of Structures in the Solar Corona

C. E. DeForest

Fine-scale structure in the corona appears not to be well resolved by current imaging instruments. Assuming this to be true offers a simple geometric explanation for several curren…

Latest results on Jovian disk X-rays from XMM-Newton

G. Branduardi-Raymont, A. Bhardwaj, R. F. Elsner +6

We present the results of a spectral study of the soft X-ray emission (0.2-2.5 keV) from low-latitude (`disk') regions of Jupiter. The data were obtained during two observing campa…

Fluxon Modeling of Low-Beta Plasmas

Craig E. DeForest, Charles C. Kankelborg

We have developed a new, quasi-Lagrangian approach for numerical modeling of magnetohydrodynamics in low to moderate plasmas such as the solar corona. We introduce the concept…

Observations Supporting the Role of Magnetoconvection in Energy Supply to the Quiescent Solar Atmosphere

Scott W. McIntosh, Alisdair R. Davey, Donald M. Hassler +4

Identifying the two physical mechanisms behind the production and sustenance of the quiescent solar corona and solar wind poses two of the outstanding problems in solar physics tod…

A Re-appraisal of the Habitability of Planets Around M Dwarf Stars

Jill C. Tarter, Peter R. Backus, Rocco L. Mancinelli +29

Stable, hydrogen-burning, M dwarf stars comprise about 75% of all stars in the Galaxy. They are extremely long-lived and because they are much smaller in mass than the Sun (between…

Ultraviolet Spectroscopy of Comet 9P/Tempel 1 with Alice/Rosetta during the Deep Impact Encounter

Paul D. Feldman, S. Alan Stern, Andrew J. Steffl +5

We report on spectroscopic observations of periodic comet 9P/Tempel 1 by the Alice ultraviolet spectrograph on the Rosetta spacecraft in conjunction with NASA's Deep Impact mission…

First Constraints on Rings in the Pluto System

A. J. Steffl, S. A. Stern

Simple theoretical calculations have suggested that small body impacts onto Pluto's newly discovered small satellites, Nix and Hydra, are capable of generating time-variable rings…

Discovery of a Binary Centaur

K. S. Noll, H. F. Levison, W. M. Grundy +1

We have identified a binary companion to (42355) 2002 CR46 in our ongoing deep survey using the Hubble Space Telescope's High Resolution Camera. It is the first companion to be fou…

Simple Magnetic Flux Balance as an Indicator of Neon VIII Doppler Velocity Partitioning in an Equatorial Coronal Hole

Scott W. McIntosh, Alisdair R. Davey

We present a novel investigation into the relationship between simple estimates of magnetic flux balance and the Ne VIII Doppler velocity partitioning of a large equatorial coronal…

Loki, Io: New groundbased observations and a model describing the change from periodic overturn

Julie A. Rathbun, John R. Spencer

Loki Patera is the most powerful volcano in the solar system. We have obtained measurements of Loki's 3.5 micron brightness from NASA's Infrared Telescope Facility (IRTF) and have…

The Positions, Colors, and Photometric Variability of Pluto's Small Satellites from HST Observations 2005-2006

S. A. Stern, M. J. Mutchler, H. A. Weaver +1

Pluto's two small satellites, temporarily designated S/2005 P 1 and S/2005 P 2, were observed on four dates (15.1 and 18.1 May 2005, 15.7 February 2006, and 2.8 March 2006) using t…

The Discovery of Two New Satellites of Pluto

H. A. Weaver, S. A. Stern, M. J. Mutchler +6

Pluto's first known moon, Charon, was discovered in 1978 (Christy 1978) and has a diameter about half that of Pluto (Buie 1992,Young 1994, Sicardy 2005), which makes it larger rela…
