We present the occurrence of waves patterns on the southern polar region of Mars as traced by the O2 dayglow emission at λ = 1.27 µm during late winter/early spring of MY 28. The observations were carried out by the OMEGA (Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité) imaging spectrometer on board Mars Express…

First Study of Dark Matter Properties with Detected Solar Gravity Modes and Neutrinos
DOI: 10.1088/2041-8205/746/1/L12 Bibcode: 2012ApJ...746L..12T

García, R. A.; Mathur, S.; Lopes, I. +5 more

We derive new limits on the cold dark matter properties for weakly interacting massive particles (WIMPs), potentially trapped in the solar core by using for the first time the central temperature constrained by boron neutrinos and the central density constrained by the dipolar gravity modes detected with the Global Oscillations at Low Frequency/So…

WISE/NEOWISE Preliminary Analysis and Highlights of the 67p/Churyumov-Gerasimenko near Nucleus Environs

On 2010 January 18-19 and June 28-29, the Wide-field Infrared Survey Explorer (WISE) spacecraft imaged the Rosetta mission target, comet 67P/Churyumov-Gerasimenko. We present a preliminary analysis of the images, which provide a characterization of the dust environment at heliocentric distances similar to those planned for the initial spacecraft e…

The Chandrayaan-1 X-ray Spectrometer: First results
DOI: 10.1016/j.pss.2011.08.014 Bibcode: 2012P&SS...60..217W

Grande, M.; Koschny, D.; Rothery, D. A. +30 more

We present X-ray fluorescence observations of the lunar surface, made by the Chandrayaan-1 X-ray Spectrometer during two solar flare events early in the mission (12th December 2008 and 10th January 2009). Modelling of the X-ray spectra with an abundance algorithm allows quantitative estimates of the MgO/SiO2 and Al2O3

Identification and physical properties of craters on Asteroid (2867) Steins
DOI: 10.1016/j.icarus.2012.08.008 Bibcode: 2012Icar..221.1119B

Jorda, L.; Lamy, P.; Barbieri, C. +2 more

We report on the physical properties of the craters of Asteroid (2867) Steins based on an analysis of images obtained with the OSIRIS instrument during the Rosetta flyby that took place on 5 September 2008. To compensate for the limited spatial resolution of the images and unfavorable illumination conditions, we applied three different filtering t…

The Deep Look at the Hard X-Ray Sky: The Swift-INTEGRAL X-Ray (SIX) Survey
DOI: 10.1088/0067-0049/201/2/34 Bibcode: 2012ApJS..201...34B

Greiner, Jochen; Ajello, Marco; Bottacini, Eugenio

The supermassive black holes at the center of active galactic nuclei (AGNs) are surrounded by obscuring matter that can block nuclear radiation. Depending on the amount of blocked radiation, the flux from the AGN can be too faint to be detected by currently flying hard X-ray (above 15 keV) missions. At these energies only ~1% of the intensity of t…

Alessi 95 and the short-period Cepheid SU Cassiopeiae
DOI: 10.1111/j.1365-2966.2012.20806.x Bibcode: 2012MNRAS.422.2501T

Gieren, W. P.; Alessi, B.; Storm, J. +6 more

The parameters for the newly discovered open cluster Alessi 95 are established on the basis of available photometric and spectroscopic data, in conjunction with new observations. Colour excesses for spectroscopically observed B- and A-type stars near SU Cas follow a reddening relation described by E(U-B)/E(B-V) = 0.83 + 0.02E(B-V), implying a valu…

Clancy, R. Todd; Sandor, Brad J.

Spectroscopically resolved observations of the 625.9 GHz H35Cl absorption lines were obtained with the James Clerk Maxwell Telescope on October 23, November 7, and December 5, 2010. The nightside atmosphere was observed on all three dates, and the dayside morning crescent was also observed on December 5. Shape of the pressure-broadened …

Scientific Analysis within SEPServer - New Perspectives in Solar Energetic Particle Research: The Case Study of the 13 July 2005 Event
DOI: 10.1007/s11207-012-0164-9 Bibcode: 2012SoPh..281..333M

Vainio, R.; Valtonen, E.; Riihonen, E. +19 more

Solar energetic particle (SEP) events are a key ingredient of solar-terrestrial physics both for fundamental research and space weather applications. Multi-satellite observations are an important and incompletely exploited tool for studying the acceleration and the coronal and interplanetary propagation of the particles. While STEREO uses for this…

A comprehensive study of RXTE and INTEGRAL observations of the X-ray pulsar 4U 1907+09

Şahiner, Ş.; Baykal, A.; Inam, S. Ç.

We analyse observations of the accretion-powered pulsar 4U 1907+09 from the International Gamma-Ray Astrophysics Laboratory (INTEGRAL; between 2005 October and 2007 November) and from the Rossi X-ray Timing Explorer (RXTE; between 2007 June and 2011 March). Using observations from the Imager on-board the INTEGRAL satellite (IBIS), the INTEGRAL Sof…
