Sentences with word «midplane»

Alternatively, turbulence or charging effects might lead to a reservoir of small grains at the surface layer that is not affected by the dust growth and fragmentation cycle dominating the dense disk midplane.
[3] Radial variation of chemical species in the disc midplane composition, and specifically the locations of snowlines, are crucial for understanding the chemistry of nascent planets.The snowlines mark the boundary beyond which a particular volatile chemical species is frozen out onto dust grains.
Interestingly, it shows a prominent equatorial dark lane sandwiched between two brighter features, due to relatively low temperature and high optical depth near the disk midplane.
Sixty hours later my little girl, Jemima, was born following induction via mid-forceps [an obstetric operation in which forceps are applied to the baby's head when it has reached the midplane of the mother's pelvis].
Unlike the normal variety of the stuff, which is fairly inert, this novel type of dark matter loses energy over time and settles into a thin disk in the midplane of our galaxy.
It was injected 9 astronomical units from the central prostar and is now in the disk's midplane.
ALMA is sensitive to shorter wavelengths that come from dust grains in the midplane of the disk, and its images of the star HL Tauri in 2014 and TW Hydrae this year showed smooth, symmetrical disks with dark circular «gaps» extending far beyond Neptune - like orbits (see picture below).
I will present new numerical models that treat dust coagulation / fragmentation, dust dynamics, simple gas - grain chemistry, and vapor diffusion simultaneously, and explore the connection between the water vapor in the disk atmosphere and the size - distribution and ice - to - rock ratios of the dust grains growing in the midplane.
Models by coauthor Hannah Jang - Condell, a former Carnegie postdoctoral researcher, showed that the disk was brighter than expected, which indicates that very small dust grains are being lifted high above the midplane.
We determine the scattering surface height above the midplane, based on the projected ring center offsets.
These grains weren't seen, which probably means that they have grown and sunk to the midplane of the disk where they can aggregate into water - rich planets.
For a counterintuitive relative flow direction — parallel to the disk midplane — we find that the structures generated by these distortions can very roughly approximate the HD 61005 morphology.
