Magnetic topologies of the Herbig Ae/Be stars
E. Alecian, G. A. Wade, C. Catala +9
Our recent discoveries of magnetic fields in a small number of Herbig Ae/Be (HAeBe) stars, the evolutionary progenitors of main sequence A/B stars, raise new questions about the or…
Computing the Rank and a Small Nullspace Basis of a Polynomial Matrix
Arne Storjohann, Gilles Villard
We reduce the problem of computing the rank and a nullspace basis of a univariate polynomial matrix to polynomial matrix multiplication. For an input n x n matrix of degree d over…
Turbulence and Magnetic Fields in Clouds
Shantanu Basu
We discuss several categories of models which may explain the IMF, including the possible role of turbulence and magnetic fields.
Magnetic Fields in Molecular Cloud Cores
Shantanu Basu
Observations of magnetic field strengths imply that molecular cloud fragments are individually close to being in a magnetically critical state, even though both magnetic field and…
A Generalized Potential with Adjustable Slope: A Hydrostatic Alternative to Cluster Cooling Flows
Andisheh Mahdavi
I discuss a new gravitational potential, Phi(r) ~ (r_0^n+r^n)^(-1/n), for modeling the mass distribution of spherical systems. This potential has a finite mass and generates a dens…
On quantizing semisimple basic algebras II: The general case
Mark J. Gotay
We prove that there is no consistent polynomial quantization of the coordinate ring of a basic non-nilpotent coadjoint orbit of a semisimple Lie group.
