Hi-Res Spectroscopy of a Volume-Limited Hipparcos Sample within 100 parsec
P. L. Lim, J. A. Holtzman, V. V. Smith +1
We obtain high-resolution echelle spectra of evolved Hipparcos stars within 100 parsec for detailed abundance analysis. We are particularly interested in subgiants because their ag…
Star Formation Histories of Local Group Dwarf Galaxies
Andrew E. Dolphin, Daniel R. Weisz, Evan D. Skillman +1
We report preliminary results of a project to homogeneously measure star formation histories for the majority of Local Group dwarf galaxies, based on archival WFPC2 observations. F…
Planetary Transits of TRES-1
A. Price, R. Bissinger, G. Laughlin +15
Observations of TRES-1b transits made during the late summer and fall 2004 observing season reveal a statistically significant but low amplitude brightening event during egress.
L-dwarf variability: Magnetic star spots or non-uniform clouds?
Christopher R. Gelino, Mark S. Marley, Jon A. Holtzman +2
The recent discovery of photometric variations in L dwarfs has opened a discussion on the cause of the variations. We argue against the existence of magnetic spots in these atmosph…
Particle-Mesh code for cosmological simulations
Anatoly Klypin, Jon Holtzman
Particle-Mesh (PM) codes are still very useful tools for testing predictions of cosmological models in cases when extra high resolution is not very important. We release for public…
Small-Scale Power Spectrum and Correlations in LCDM
Anatoly Klypin, Joel Primack, Jon Holtzman
Cosmological models with a positive cosmological constant and have a number of attractive features. A larger Hubble constant, which can be compatible with the recent HST es…
