A Young Planet Search in Visible and IR Light: DN Tau, V836 Tau, and V827 Tau
L. Prato, M. Huerta, C. M. Johns-Krull +3
In searches for low-mass companions to late-type stars, correlation between radial velocity variations and line bisector slope changes indicates contamination by large starspots. T…
Time-Resolved AU-Scale Jets Traced by Masers in the IRAS 4A/B Regions of NGC1333
Kevin B. Marvel, Bruce A. Wilking, Mark J Claussen +1
We present results of VLBI observations of the water masers associated with IRAS 4A and IRAS 4B in the NGC 1333 star-forming region taken in four epochs over a two month period. Bo…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
Chemical Abundances and Kinematics in Globular Clusters and Local Group Dwarf Galaxies and Their Implications for Formation Theories of the Galactic Halo
Doug Geisler, George Wallerstein, Verne V. Smith +1
We review Galactic halo formation theories and supporting evidence, in particular kinematics and detailed chemical abundances of stars in some relevant globular clusters as well as…
Quantitative comparison between Type Ia supernova spectra at low and high redshifts: A case study
G. Garavini, G. Folatelli, S. Nobili +44
We develop a method to measure the strength of the absorption features in Type Ia supernova (SN Ia) spectra and use it to make a quantitative comparison between the spectra of Type…
First VLBI mapping of a rare SiO isotopic substitution
R. Soria-Ruiz, F. Colomer, J. Alcolea +3
We report the first VLBI map of the 7 mm v=0 J=1-0 maser line of the 29-SiO isotopic substitution in the long period variable star IRC+10011. We have found that this maser emission…
