The Astrophysical Journal, 2023 Characterizing the physical properties of dust grains in a protoplanetary disk is critical to comprehending the planet formation process. Our study presents Atacama Large Millimeter/submillimeter Array (ALMA) high-resolution observations of the young ...

Dust Formation in Hot Stellar Winds [PDF]
Symposium - International Astronomical Union, 1995 WC-type Wolf-Rayet stars show episodic or persistent infrared emission attributed to amorphous carbon grains forming in their winds. The process of dust formation in the hydrogen-poor environments characteristic of WC winds is reviewed and compared to the chemical pathway to soot particle production in AGB stars. Emphasis is put on the formation of the

Indoor and outdoor dust in Damaturu Nigeria : composition, exposure and risk to human health [PDF]
, 2013 Harmattan and Dust (sand) storms together with anthropogenic activities including the use of firewood and kerosene as fuel for cooking, and diesel/petrol generators for electricity generation are potential sources of particulate and gaseous pollutants in

Symposium - International Astronomical Union, 1973 The view that dust is essential to star formation is challenged on the ground that other interstellar constituents can provide more rapid cooling. From the evidence of stellar minimum masses it is suggested that self absorption of the radiation emitted by the coolant H2 is the dominant mechanism leading to the heating of a collapsing fragment.

Galaxy simulation with dust formation and destruction [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We perform smoothed particle hydrodynamics (SPH) simulations of an isolated galaxy with a new treatment for dust formation and destruction. To this aim, we treat dust and metal production self-consistently with star formation and supernova feedback. For dust, we consider a simplified model of grain size distribution by representing the entire range of ...

Evading the dust fragmentation barrier with the streaming instability in protoplanetary disks
Astronomy & AstrophysicsContext. The streaming instability (SI) is a leading candidate for reaching solid densities sufficient to trigger the gravitational collapse needed for the formation of planetesimals. However, dust growth barriers appear to impede the ability to assemble
