The Quest for Microwave Foreground X
Angelica de Oliveira-Costa, Max Tegmark, R. D. Davies +4
The WMAP team has produced a foreground map that can account for most of the low-frequency Galactic microwave emission in the WMAP maps, tentatively interpreting it as synchrotron…
Lithium in stars with exoplanets
Garik Israelian, Nuno Santos, Michel Mayor +1
We present a comparison of the lithium abundances of stars with and without planetary-mass companions. New lithium abundances are reported in 79 planet hosts and 38 stars from a co…
Searching for non-Gaussianity in the VSA data
Richard Savage, Richard A. Battye, Pedro Carreira +28
We have tested Very Small Array (VSA) observations of three regions of sky for the presence of non-Gaussianity, using high-order cumulants, Minkowski functionals, a wavelet-based t…
Photometric variability of a young, low-mass brown dwarf
M. R. Zapatero Osorio, J. A. Caballero, V. J. S. Bejar +1
We report differential I-band and J-band photometry of S Ori 45, a cool (M8.5), young (1-8 Myr) brown dwarf of the sigma Orionis cluster with a likely mass estimated at around 20 t…
New measurement of the Lithium-6/Lithium-7 isotopic ratio in the extra-solar planet host star HD82943 and line blending in the Li 6708 A region
Garik Israelian, Nuno Santos, Michel Mayor +1
The presence of possible blends in the spectral region of the Li resonance line at 6708 A in solar-type metal-rich stars is investigated using high resolution and high signal-to-no…
