Observation of the Double Sodium Layer Over Haikou, China by Lidar
Lidar, Double Sodium Layer Mesosphere and Lower-Thermosphere
2013/10/3
A Double Sodium Layer (DSL) structure was observed during the night of August 22, 2011 over Haikou, China (20°N, 110°E) by Na lidar. This DSL comprised a typical sodium layer at altitudes of 80~105km ...
Gyroscopic Pumping in the Solar Near-Surface Shear Layer
Gyroscopic Pumping Solar Near-Surface
2011/9/29
We use global and local helioseismic inversions to explore the prevailing dynamical balances in the solar Near-Surface Shear Layer (NSSL). The differential rotation and meridional circulation are inti...

two-layer Maclaurin ellipsoids: Application to planets and satellites
2011/10/12
The exact solution for the shape and gravitational field of a rotating two-layer Maclaurin ellipsoid of revolution is compared with predictions of the theory of figures up to third order in the small ...
On the source of dense outflows from T Tauri Stars. and III. Winds driven from the star-disc shear layer
stars pre-main-sequence stars: winds outflows stars circumstellar matter – stars formation
2010/11/11
Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (Te ≃ 80, 000 K) and dense (ne ≃ 1010 cm−3) component associated with the large scale jet. ...
Alpha effect due to buoyancy instability of a magnetic layer

Context. A strong toroidal field can exist in form of a magnetic layer in the overshoot region below the solar convection zone. This motivates a more detailed study of the magnetic buoyancy instabilit...
A mid-sized asteroid impact with the ocean could drastically deplete the ozone layer for many years, according to a team of US researchers. Such damage would expose the surface to levels of UV radiati...
