Imaging the inner ear in fossil mammals: High-resolution CT scanning and 3-D virtual reconstructions
The bony labyrinth of mammals, a delicate and complex cavity within the petrosal, houses the organs of hearing and equilibrium of the inner ear. Because this region is typically lodged deep within the skull, there have been few morphological studies of the bony labyrinth in fossils—where it frequently is completely enveloped by surrounding bone and sediment matrix. The recent development of hig...
متن کامل3D imaging and modeling of the middle and inner ear
The bones of the middle ear are the smallest bones in the body and are among the most complicated functionally. They are located within the temporal bone – rendering them difficult to access and study. An accurate 3D model can offer an excellent illustration of the complex spatial relationships between the ossicles and the nerves and muscles with which they intertwine. The overall objective was...
متن کاملEta Carinae: Bullet Streams and Colliding Wind Shocks
Eta Carinae, the most massive and most luminous star in our Galaxy, erupted in 1842 with an energy rivaling a supernova. It ejected approximately two solar masses of material to form an extended bipolar nebula (the homunculus), a variety of massive “bullets” (NN and NS knots and the South Bar) and the “spikes” (long narrow strings of bullets). We have performed spatial and spectral astrometry o...
متن کاملThe [o Iii] Veil: Astropause of Eta Carinae’s Wind?
We present narrowband images of η Carinae in the light of [O iii] λ5007 obtained with the Hubble Space Telescope/Wide Field Planetary Camera 2 (HST/WFPC2), as well as a groundbased image in the same emission line with a larger field of view. These images show a thin veil of [O iii] emission around η Car and its ejecta, confirming the existence of an oxygen-bearing “cocoon” inferred from spectra...
