Dynamical Mass Constraints on Low-Mass Pre-Main-Sequence Stellar Evolutionary Tracks: An Eclipsing Binary in Orion with a 1.0 Msun Primary and an 0.7 Msun Secondary
Keivan G. Stassun, Robert D. Mathieu, Luiz Paulo R. Vaz +2
We report the discovery of a double-lined, spectroscopic, eclipsing binary in the Orion star-forming region. We analyze the system spectroscopically and photometrically to empirica…
Searching for Planets in the Hyades III: The Quest for Short-Period Planets
D. Paulson, S. Saar, W. Cochran +1
We have been using the Keck I High Resolution Spectrograph (HIRES) to search for planetary companions in the Hyades cluster. We selected four stars from this sample which showed si…
Galactic Point Sources of TeV Antineutrinos
Luis A. Anchordoqui, Haim Goldberg, Francis Halzen +1
High energy cosmic ray experiments have identified an excess from the region of the Galactic Plane in a limited energy range around eV (EeV). This is very suggestive of n…
The Uncertainty in Newton's Constant and Precision Predictions of the Primordial Helium Abundance
Robert J. Scherrer
The current uncertainty in Newton's constant, G_N, is of the order of 0.15%. For values of the baryon to photon ratio consistent with both cosmic microwave background observations…
New Constraints on , , and w from an Independent Set of Eleven High-Redshift Supernovae Observed with HST
R. A. Knop, G. Aldering, R. Amanullah +45
We report measurements of , , and w from eleven supernovae at z=0.36-0.86 with high-quality lightcurves measured using WFPC-2 on the HST. This is an independent set of hi…
The intrinsic colour dispersion in Type Ia supernovae
S. Nobili, A. Goobar, R. Knop +1
The properties of low-redshift Type Ia supernovae are investigated using published multi-band optical broadband data from the Calan/Tololo and CfA surveys. The average time evoluti…
Physics with Cosmic Neutrinos, PeV to ZeV
Thomas J. Weiler
We begin with a brief overview of highest-energy cosmic ray data, and the experiments which will perform neutrino astronomy. We then discuss two particle physics aspects of neutrin…
Fine Scale Temperature Fluctuations in the the Orion Nebula and the t^2 Problem
C. R. O'Dell, M. Peimbert, A. Peimbert
We present a high spatial resolution map of the columnar electron temperature (Tc) of a region to the south west of the Trapezium in the Orion Nebula. This map was derived from Hub…
Detections of Ro-Vibrational H Emission from the Disks of T Tauri Stars
J. S. Bary, D. A. Weintraub, J. H. Kastner
We report the detection of quiescent H_2 emission in the v=1-0 S(1) line at 2.12183 um in the circumstellar environment of two classical T Tauri stars, GG Tau A and LkCa 15, in hig…
