Top-shaped asteroids as Lens-shaped bodies
نویسندگان
چکیده
Several asteroids are known to be shaped like toy tops. This paper models Top-Shaped Asteroids (TSAs) as Homogeneous Symmetric Lenses (HSLs), and derives their rotational, self-gravitational, total energies functions of mass, density, angular momentum. Then we raise, test, ultimately reject the hypothesis that TSAs take shape lowest energy, subject constraint they keep same momentum, while remaining HSLs. Other processes must control shapes TSAs. For completeness, also describe a Core-Mantle Model for TSAs, well an Inverted Model, derive self-gravitational energies, along with rotational energies. The gravitational potential at center HSL then is derived.

Curvature Evolution of Nonconvex Lens-shaped Domains
We study the curvature flow of planar nonconvex lens-shaped domains, considered as special symmetric networks with two triple junctions. We show that the evolving domain becomes convex in finite time; then it shrinks homothetically to a point, as proved in [22]. Our theorem is the analog of the result of Grayson [13] for curvature flow of closed planar embedded curves.

متن کاملCenter of Mass Estimation of Simple Shaped Magnetic Bodies Using Eigenvectors of Computed Magnetic Gradient Tensor
Computed Magnetic Gradient Tensor (CMGT) includes the first derivatives of three components of magnetic field of a body. At the eigenvector analysis of Gravity Gradient Tensors (GGT) for a line of poles and point pole, the eigenvectors of the largest eigenvalues (first eigenvectors) point precisely toward the Center of Mass (COM) of a body. However, due to the nature of the magnetic field, it i...
متن کاملStar-Shaped and L-Shaped Orthogonal Drawings
An orthogonal drawing of a plane graph G is a planar drawing of G, denoted by D(G), such that each vertex of G is drawn as a point on the plane, and each edge of G is drawn as a sequence of horizontal and vertical line segments with no crossings. An orthogonal polygon P is called orthogonally convex if the intersection of any horizontal or vertical line L and P is either a single line segment o...
متن کاملInfluence of After Body Shape on the Performance of Blunt Shaped Bodies as Vortex Shedders
The present study explores flow visualization experiments with various blunt shaped bluff bodies placed inside a circular pipe. The bodies mainly comprise of modifications of trapezoidal cylinder, most widely used in practical applications, such as vortex flowmeters. The present configuration possesses the feature of both internal and external flows with low aspect ratio. The vortex dynamics of...
