A Cusp Slope -- Central Anisotropy Theorem
J. An, N. W. Evans
For a wide class of self-gravitating systems, we show that if the density is cusped like 1/r^{gamma} near the center, then the limiting value of the anisotropy parameter beta = 1 -…
Galaxy Models with Tangentially Anisotropic Velocity Distributions
J. H. an, N. W. Evans
This paper provides two families of flexible and simple galaxy models. Representatives of many of the families possess the important cosmological cusps, with the density behaving l…
Hypervirial Models of Stellar Systems
N. W. Evans, J. An
A family of cusped potential-density pairs is presented for modelling galaxies and dark haloes. The density profile is cusped like 1/r^(2-p) at small radii. The distribution functi…
High-Precicison Limb-Darkening Measurement of a K3 Giant Using Microlensing
Dale L. Fields, M. D. Albrow, J. An +21
We obtain high-precision limb-darkening measurements in five bands (V, V_E, I_E, I, and H) for the K3 III (Teff=4200 K, [Fe/H]=+0.3, log(g)=2.3) source of the Galactic bulge microl…
