β-curves for amorphous carbon (‘C’, green lines, Kimura & Mann 1999), astronomical silicates (“SiO”, solid gold line, Gustafson 1994; and blue lines, Kimura & Mann 1999), and adapted astronomical silicates (“ad. SiO”) with an assumed dust density of ρd = 2500 kg/m3 (thick dashed maroon line; Sterken et al. 2012a). The β-curves of Kimura & Mann (1999) have porosities, p, ranging from 0% (compact particles) to 93% (fluffy particles), indicated by different line styles.

Interstellar Dust Measured In Situ by Ulysses

by Keith CowingJuly 2, 2025July 2, 2025

Impacts of interstellar dust (ISD) grains on the Ulysses spacecraft allowed for the first successful in situ measurement of ISD (Grün et al. 1993).
