Dense molecular cloud cores as a source of micrometer-sized grains in galaxies

Li, Zhi-Yun; Hirashita, Hiroyuki; Nozawa, Takaya +2 more

Coreshine in dense molecular cloud cores (dense cores) is interpreted as evidence for micrometer-sized grains (referred to as very large grains, VLGs). VLGs may have a significant influence on the total dust amount and the extinction curve. We estimate the total abundance of VLGs in the Galaxy, assuming that dense cores are the site of VLG formati…

A multifractal approach applied to the magnetic field turbulence in Jupiter's magnetosheath

Bolzan, M. J. A.; Echer, E.

We studied the magnetic field turbulence in Jupiter's magnetosheath during the Ulysses inbound trajectory in 1992. This analysis was conducted using nonlinear techniques such as kurtosis, probability density functions, multifractal approach and wavelet analysis. The results from the PDFs and kurtosis analysis, for each magnetic field component, sh…
