Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet's geochemical evolution
Larry R. Nittler, Asmaa Boujibar, Ellen Crapster-Pregont +6
Mercury, the innermost planet, formed under highly reduced conditions, based mainly on surface Fe, S, and Si abundances determined from MESSENGER mission data. The minor element Cr…
Evidence for Widespread Hydrogen Sequestration within the Moon's South Polar Cold Traps
Timothy P. McClanahan, J. J. Su, Richard D. Starr +5
The measured neutron flux from the Moons south polar region shows evidence of locally enhanced hydrogen concentrations, likely in the form of water ice, within most permanently sha…
The Second Catalog of Interplanetary Network Localizations of Konus Short Duration Gamma-Ray Bursts
D. Svinkin, K. Hurley, A. Ridnaia +72
We present the catalog of Interplanetary Network (IPN) localizations for 199 short-duration gamma-ray bursts (sGRBs) detected by the Konus-Wind (KW) experiment between 2011 January…
Calibration and validation of the lunar exploration neutron detector (LEND) observations for the study of the moon volatiles
J. J. Su, T. P. McClanahan, A. M. Parsons +6
This paper reviews improved calibration methods for the Lunar Reconnaissance Orbiter Lunar Exploration Neutron Detector. We cross calibrated the set of LEND observations and models…
A bright gamma-ray flare interpreted as a giant magnetar flare in NGC 253
D. Svinkin, D. Frederiks, K. Hurley +33
Magnetars are young, highly magnetized neutron stars that produce extremely rare giant flares of gamma-rays, the most luminous astrophysical phenomena in our Galaxy. The detection…
Global Major-Element Maps of Mercury from Four Years of MESSENGER X-Ray Spectrometer Observations
Larry R. Nittler, Elizabeth A. Frank, Shoshana Z. Weider +4
The X-Ray Spectrometer (XRS) on the MESSENGER spacecraft provided measurements of major-element ratios across Mercury's surface. We present global maps of Mg/Si, Al/Si, S/Si, Ca/Si…
