Pairing mechanisms for binary stars
M. B. N. Kouwenhoven, A. G. A. Brown, S. P. Goodwin +2
Knowledge of the binary population in stellar groupings provides important information about the outcome of the star forming process in different environments. Binarity is also a k…
High Accuracy Imaging Polarimetry with NICMOS
D. Batcheldor, G. Schneider, D. C. Hines +5
The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2-1.5%. To better quantify an…
f(R) Gravity and Chameleon Theories
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +1
We analyse f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) t…
Enormous disc of cool gas surrounding the nearby powerful radio galaxy NGC 612 (PKS 0131-36)
B. H. C. Emonts, R. Morganti, T. A. Oosterloo +5
We present the detection of an enormous disc of cool neutral hydrogen (HI) gas surrounding the S0 galaxy NGC 612, which hosts one of the nearest powerful radio sources (PKS 0131-36…
Lack of initial conditions dependence of fluctuations in warm inflation
Arjun Berera, Lisa M. H. Hall, Ian G. Moss +1
Warm inflation dynamics is fundamentally based on a system-reservoir configuration in which the dynamics is dictated by a fluctuation-dissipation relation. Recent work by Cerioni e…
Probing the Early Evolution of Young High-Mass Stars
E. Puga, A. Bik, L. B. M. F. Waters +22
Near-infrared imaging surveys of high-mass star-forming regions reveal an amazingly complex interplay between star formation and the environment (Churchwell et al. 2006; Alvarez et…
