SOHO`s Frequently Asked Questions
... Good question. Even scientists can debate the answer to this one. Two leading answers are "yellowish-white" and "green." Our eyes perceive sunlight as being yellow or white -- but DO NOT LOOK AT the Sun to confirm this! It is also correct to say it is "green," too, because the Sun's peak wavelength ...

Chapter 4 The Formation of Population III stars in a ΛCDM universe
... Figures 4.1, 4.2, and 4.3 zoom in on the central gas core in each halo at the redshift of collapse by factors of four, showing projections of log baryon density, log baryon temperature, and maximum refinement level, respectively. The largest-scale panel shows a projection of a volume of the universe ...

The Correlation of Lithium and Beryllium in F and G
... CORRELATION OF Li AND Be IN F AND G DWARF STARS There is relatively less information on Be abundances because (1) it is more difficult to observe the resonance lines of Be ii near the atmospheric cutoff near 3000 8, (2) there is more line blending in that spectral region, which can blur the spectra ...
