Chondrule Formation During Low-Speed Collisions of Planetesimals: A Hybrid Splash-Flyby Framework
William Herbst, James P. Greenwood
Chondrules probably formed during a small window of time 1-4 Ma after CAIs, when most solid matter in the asteroid belt was already in the form of km-sized planetesimals. The…
The Macroporosity of Rubble Pile Asteroid Ryugu and Implications for the Origin of Chondrules
William Herbst, James P. Greenwood, Teng Ee Yap
We use the known surface boulder-size distribution of the C-type rubble pile asteroid Ryugu (NEA 162173) to determine its macroporosity, assuming it is a homogeneous granular aggre…
A Radiative Heating Model for Chondrule and Chondrite Formation
William Herbst, James P. Greenwood
We propose that chondrules and chondrites formed together during a brief radiative heating event caused by the close encounter of a small (m to km-scale), primitive planetesimal (S…
A New Mechanism for Chondrule Formation: Radiative Heating by Hot Planetesimals
William Herbst, James P. Greenwood
We propose that chondrules are formed by radiative heating of pre-existing dust clumps during close fly-bys of planetesimals with incandescent lava at their surfaces. We show that…
