The Hubble Legacy Archive ACS grism data
Walsh, J. R.; Rosati, P.; Kümmel, M. +8 more
A public release of slitless spectra, obtained with ACS/WFC and the G800L grism, is presented. Spectra were automatically extracted in a uniform way from 153 archival fields (or "associations") distributed across the two Galactic caps, covering all observations to 2008. The ACS G800L grism provides a wavelength range of 0.55-1.00 µm, with a …

Kernel spectral clustering of time series in the CoRoT exoplanet database
Debosscher, J.; Varón, C.; Alzate, C. +1 more
Context. Detection of contaminated light curves and irregular variables has become a challenge when studying variable stars in large photometric surveys such as that produced by the CoRoT mission.
Aims: Our goal is to characterize and cluster the light curves of the first four runs of CoRoT, in order to find the stars that cannot be classifie…
Identification of a Complete 160 µm Flux-limited Sample of Infrared Galaxies in the ISO Lockman Hole 1 deg2 Deep Fields: Source Properties and Evidence for Strong Evolution in the FIR Luminosity Function for ULIRGs
Aussel, H.; Le Floc'h, E.; Veilleux, S. +13 more
We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 µm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman Hole (LH). Ground-based UV, optical, and near-infrared (NIR) photometry and optical spectroscopy have been used to det…

Meridional Flow Observations: Implications for the current Flux Transport Models
Howe, Rachel; Komm, Rudolf; Hill, Frank +2 more
Meridional circulation has become a key element in the solar dynamo flux transport models. Available helioseismic observations from several instruments, Taiwan Oscillation Network (TON), Global Oscillation Network Group (GONG) and Michelson Doppler Imager (MDI), have made possible a continuous monitoring of the solar meridional flow in the subphot…
Dispersive MHD turbulence in one dimension
Passot, T.; Sulem, P. L.; Laveder, D. +1 more
Numerical simulations of dispersive turbulence in magnetized plasmas based on the Hall-MHD description are presented, assuming spatial variations along a unique direction making a prescribed angle with the ambient magnetic field. Main observations concern the energy transfers among the different scales and the various types of MHD waves, together …
New Precision Orbits of Bright Double-lined Spectroscopic Binaries. VII. 47 Andromedae, 38 Cassiopeiae, and HR 8467
Williamson, Michael H.; Fekel, Francis C.; Pourbaix, Dimitri +1 more
Improved orbital elements for three double-lined spectroscopic binaries, 47 And, 38 Cas, and HR 8467, have been determined with extensive new radial velocities. For 38 Cas lines of the secondary have been detected for the first time. Given the orbital periods for these systems of 35.3682, 134.130, and 42.3813 days, respectively, it is not surprisi…
An SLS4 Longitude System Based on a Tracking Filter Analysis of the Rotational Modulation of Saturn Kilometric Radiation
Gurnett, D. A.; Kurth, W. S.; Averkamp, T. F. +3 more
Saturn has been known for over thirty years to emit an intense radio emission at kilometer wavelengths called Saturn Kilometric Radiation (SKR) that is modulated by the rotation of the planet. Although the period of this modulation was initially thought to represent the rotation period of the planet, it is now known that the radiation has two dist…
Plasma transition at the flanks of the Venus ionosheath: Evidence from the Venus Express data
Barabash, S.; Lundin, R.; Zhang, T. L. +6 more
Measurements conducted with the Analyzer of Space Plasmas and Energetic Atoms (ASPERA-4) instrument in the Venus Express spacecraft reveal the presence of a plasma transition within a boundary layer that extends along at the flanks of the Venus ionosheath and where the solar wind exhibits changes similar to those reported from previous missions (M…
