Spectroscopic evidence for helicity in explosive events
Sun: UV radiation—Sun: transition region— Sun: chromosphere
2011/9/30
We report spectroscopic observations in support of a novel view of transition region explosive events, observations that lend empirical evidence that at least in some cases explosive events may be not...
Li - O anti-correlation in NGC 6752: evidence for Li-enriched polluting gas
stars abundances – globular clusters individual NGC6752 – stars late-type
2010/11/11
Context. Elemental correlations and anti-correlations are known to be present in globular clusters (GCs) owing to pollution by CNO cycled gas. Because of its fragility Li is destroyed at the temperatu...
Evidence of major dry mergers at M* > 2 x 10^11 Msun from curvature in early-type galaxy scaling relations?
galaxies formation
2010/11/11
For early-type galaxies, the correlations between stellar mass and size, velocity dis-
persion, surface brightness, color, axis ratio and color-gradient all indicate that two mass scales, M∗ = ...
Power Spectrum Analysis of Physikalisch-Technische Bundesanstalt Decay-Rate Data: Evidence for Solar Rotational Modulation
Solar and Stellar Astrophysics (astro-ph.SR) Nuclear Experiment (nucl-ex) Instrumentation and Detectors (physics.ins-det)
2010/12/29
Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes.
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
