Phantom Dark Energy Models with a Nearly Flat Potential
Robert J. Scherrer, A. A. Sen
We examine phantom dark energy models produced by a field with a negative kinetic term and a potential that satisfies the slow roll conditions: [(1/V)(dV/dphi)]^2 << 1 and (1/V)(d^…

Surprising dissimilarities in a newly formed pair of 'identical twin' stars
Keivan G. Stassun, Robert D. Mathieu, Phillip A. Cargile +3
The mass and chemical composition of a star are the primary determinants of its basic physical properties--radius, temperature, luminosity--and how those properties evolve with tim…

Evolution of Oscillating Scalar Fields as Dark Energy
Sourish Dutta, Robert J. Scherrer
Oscillating scalar fields, with an oscillation frequency much greater than the expansion rate, have been proposed as models for dark energy. We examine these models, with particula…
