Constraining the Age-Activity Relation for Cool Stars: The SDSS DR5 Low-Mass Star Spectroscopic Sample
Andrew A. West, Suzanne L. Hawley, John J. Bochanski +5
We present a spectroscopic analysis of over 38,000 low-mass stars from the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5). Analysis of this unprecedentedly large sample confi…
Thawing quintessence with a nearly flat potential
Robert J. Scherrer, A. A. Sen
The thawing quintessence model with a nearly flat potential provides a natural mechanism to produce an equation of state parameter, w, close to -1 today. We examine the behavior of…
The Monitor project: tracking the evolution of low mass and pre-main sequence stars
Suzanne Aigrain, Jonathan Irwin, Leslie Hebb +4
The Monitor project is a large-scale program of photometric and spectroscopic monitoring of young open clusters using telescopes at ESO and other observatories. Its primary goal is…
Dirac Fields in Loop Quantum Gravity and Big Bang Nucleosynthesis
Martin Bojowald, Rupam Das, Robert J. Scherrer
Big Bang nucleosynthesis requires a fine balance between equations of state for photons and relativistic fermions. Several corrections to equation of state parameters arise from cl…
A Photometric Survey for Variables and Transits in the Field of Praesepe with KELT
Joshua Pepper, K. Z. Stanek, Richard W. Pogge +5
The Kilodegree Extremely Little Telescope (KELT) project is a small aperture, wide-angle search for planetary transits of solar-type stars. In this paper, we present the results of…
The Weak Energy Condition and the Expansion History of the Universe
A. A. Sen, Robert J. Scherrer
We examine flat models containing a dark matter component and an arbitrary dark energy component, subject only to the constraint that the dark energy satisfies the weak energy cond…
