Web2 dagen geleden · We investigate the early (t < 1 day) kilonova from the neutron star merger by deriving atomic opacities for all the elements from La to Ra (Z = 57 - 88) ionized to the states V - XI. The opacities at high temperatures for the elements with open f-shells (e.g., lanthanides) are exceptionally high, reaching kappa_{exp} ~ 10^4 cm2/g at lambda < … Web8 mei 2024 · The discovery of superionic ice potentially solves the puzzle of what giant icy planets like Uranus and Neptune are made of. They’re now thought to have gaseous, mixed-chemical outer shells, a liquid layer of ionized water below that, a solid layer of superionic ice comprising the bulk of their interiors, and rocky centers.

WebThe F layer exists from about 90 to 240 miles. During daylight hours, the F layer separates into the F1 and F2 layers. The ionization in these layers is quite high and varies widely during the day with a maximum at noon. Recombination occurs slowly after sunset, so that an ionized layer is always present.
