MESSENGER observations of large dayside flux transfer events: Do they drive Mercurys substorm cycle?
The large-scale dynamic behavior of Mercury’s highly compressedmagnetosphere is predominantly powered by magnetic reconnection, which transfers energy and momentum from the solar wind to the magnetosphere. The contribution of flux transfer events (FTEs) at the daysidemagnetopause to the redistribution of magnetic flux in Mercury’s magnetosphere is assessed with magnetic field data acquired in o...
متن کاملDistribution and compositional variations of plasma ions in Mercurys space environment: The first three Mercury years of MESSENGER observations
[1] We have analyzed measurements of planetary ions near Mercury made by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Fast Imaging Plasma Spectrometer (FIPS) over the first three Mercury years of orbital observations (25 March 2011 through 31 December 2011). We determined the composition and spatial distributions of the most abundant species in the regions sampl...
متن کاملInfluence of Chemical and Mineralogical Composition on Color for Commercial Talcs
Commercial talcs are pulverized mineral products with a variable chemical and mineralogic composition, widely used in industry. Although generally white, they have color variations. The aim of this study was to establish relationships between color parameters and the chemical and mineralogic composition of commercial talc samples, in order to investigate the causes of color. Chlorite, dolomite,...

tected, as it were, from another crossing over. This relation is illustrated in the diagram (fig. 7). If crossing over occurs at some point between two pairs of factors a and b indicated on the diagram, the next crossing over point of the chromosome would, if it occurred at all, lie at some distance away, rather than near by. This possibility can be tested in a case where several known points a...
متن کاملHollows on Mercury: MESSENGER evidence for geologically recent volatile-related activity.
High-resolution images of Mercury's surface from orbit reveal that many bright deposits within impact craters exhibit fresh-appearing, irregular, shallow, rimless depressions. The depressions, or hollows, range from tens of meters to a few kilometers across, and many have high-reflectance interiors and halos. The host rocks, which are associated with crater central peaks, peak rings, floors, an...
