Sentence examples for accretion of dust from inspiring English sources
During these years he first became associated with RA Lyttleton on problems of accretion of dust and gas around large bodies.
These are thought to be powered by the accretion of dust and other material into super-massive black holes at the centre of distant galaxies.
The researchers speculate that the formation of the planet, through accretion of dust or some sort of gravitational instability, may account for the "clearing" of the disk's thin zone.
The Hadean Eon is characterized by Earth's initial formation from the accretion of dust and gases and the frequent collisions of larger planetesimals and by the stabilization of its core and crust and the development of its atmosphere and oceans.

Stone pavement-covered accretionary deposits are a new key archive that allows quantifying the relative importance of dust accretion, slope processes, soil formation and vegetation cover.
η is the mass fraction of cold clouds where the accretion process occurs, τSN and τacc are the timescales of dust destruction and accretion, respectively.
