This service publishes spectral matrix data from the Earth magnetosphere
obtained by the CLUSTER satellites. The data contains the upper
triangle for the 5x5 correlation matrix of the three magnetic and
two electric components of the electromagnetic field in 27 frequency
bands in the SR2 reference frame. For more information, refer

The Exoplanet Orbit Database is a database of well-determined orbital parameters of exoplanets, and their host stars' properties. This database comprises spectroscopic orbital elements measured for planets orbiting their host stars from radial velocity and transit measurements as reported in the literature. The authors have also compiled fundamental transit parameters, stellar parameters, and the method used for the planets discovery. This Exoplanet Orbit Database includes all planets with robust, well measured orbital parameters reported in peer-reviewed articles. In addition to this HEASARC representation, the database is available in a searchable, filterable, and sortable form online through the Exoplanets Data Explorer table at <a href="http://exoplanets.org">http://exoplanets.org</a>, and the data can be plotted and explored through the Exoplanet Data Explorer plotter which is available at that web site. In their paper, the authors use the Data Explorer to generate publication-ready plots, giving three examples of the signatures of exoplanet migration and dynamical evolution: They illustrate the character of the apparent correlation between mass and period in exoplanet orbits, the different selection biases between radial velocity and transit surveys, and that the multi-planet systems show a distinct semi-major-axis distribution from apparently singleton systems. This table was first created by the HEASARC in August 2012 based on a machine-readable version of the Exoplanet Orbit Database which was obtained from the authors' web site (<a href="http://exoplanets.org">http://exoplanets.org</a>), file exoplanets.csv. It is updated usually within a day of whenever the source file is updated. This is a service provided by NASA HEASARC .
The Extrasolar Planets Encyclopedia is a working tool, providing all the latest detections and data that have been announced by professional astronomers, Which is intended to be used to facilitate progress in exoplanetology. Ultimately, researchers willing to make a quantitative, scientific use of the catalog can make their own judgement on the likelihood of the data and the detections. The stellar data (positions, distances, V and other magnitudes, mass, metallicities etc) are taken from Simbad or from professional papers on exoplanets. Ongoing large extrasolar planets ('exoplanets') projects include: <pre> Anglo-Australian Planet Search <<a href="http://www.phys.unsw.edu.au/~cgt/planet/AAPS_Home.html">http://www.phys.unsw.edu.au/~cgt/planet/AAPS_Home.html</a>> California & Carnegie Planet Search <<a href="http://exoplanets.org/">http://exoplanets.org/</a>> Geneva Extrasolar Planet Search Programmes <<a href="http://obswww.unige.ch/~udry/planet/planet.html">http://obswww.unige.ch/~udry/planet/planet.html</a>> Transatlantic Exoplanet Survey <<a href="http://www.astro.caltech.edu/~ftod/tres/tres.html">http://www.astro.caltech.edu/~ftod/tres/tres.html</a>> University of Texas - Dept. of Astronomy <<a href="http://www.as.utexas.edu/astronomy/research/ss.html">http://www.as.utexas.edu/astronomy/research/ss.html</a>> </pre> This table is based on the VOTable format of the catalog obtained from the Extrasolar Planets Encyclopaedia website at <a href="http://exoplanet.eu/">http://exoplanet.eu/</a>. It is maintained by Jean Schneider and is updated on a frequent basis, as needed. This is a service provided by NASA HEASARC .
Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee" helicoidal antenna, half of which being Right Handed (RH) polarized and the other half being Left Handed (LH) polarized. Four receivers are currently connected to the NDA, sampling data in spectral ranges within 5 to 80 MHz.
