Revision of VLT/UVES constraints on a varying fine-structure constant
Michael T. Murphy, John K. Webb, Victor V. Flambaum
We critically review the current null results on a varying fine-structure constant, alpha, derived from VLT/UVES quasar absorption spectra, focusing primarily on the many-multiplet…
The Metallicity of Stars with Close Companions
Daniel Grether, Charles H. Lineweaver
We examine the relationship between the frequency of close companions (stellar and planetary companions with orbital periods < 5 years) and the metallicity of their Sun-like (~ FGK…
Binarity as a key factor in protoplanetary disk evolution: Spitzer disk census of the eta Chamaeleontis cluster
J. Bouwman, W. A. Lawson, C. Dominik +4
The formation of planets is directly linked to the evolution of the circumstellar (CS) disk from which they are born. The dissipation timescales of CS disks are, therefore, of dire…
Investigating grain growth in disks around southern T Tauri stars at millimetre wavelengths
Dave Lommen, Chris M. Wright, Sarah T. Maddison +7
CONTEXT - Low-mass stars form with disks in which the coagulation of grains may eventually lead to the formation of planets. It is not known when and where grain growth occurs, as…
Asteroseismology with the WIRE satellite. I. Combining Ground- and Space-based Photometry of the Delta Scuti Star Epsilon Cephei
H. Bruntt, J. C. Suarez, T. R. Bedding +10
We have analysed ground-based multi-colour Stromgren photometry and single-filter photometry from the star tracker on the WIRE satellite of the delta scuti star Epsilon Cephei. The…
Probing variations in fundamental constants with radio and optical quasar absorption-line observations
P. Tzanavaris, M. T. Murphy, J. K. Webb +2
Nine quasar absorption spectra at 21-cm and UV rest-wavelengths are used to estimate possible variations in x=alpha^2 g_p mu, (alpha is the fine structure constant, g_p the proton…
