Phase Closure Image Reconstruction for Future VLTI Instrumentation
Mercedes E. Filho, Stephanie Renard, Paulo Garcia +21
Classically, optical and near-infrared interferometry have relied on closure phase techniques to produce images. Such techniques allow us to achieve modest dynamic ranges. In order…
Phase Referencing in Optical Interferometry
Mercedes E. Filho, Paulo Garcia, Gilles Duvert +20
One of the aims of next generation optical interferometric instrumentation is to be able to make use of information contained in the visibility phase to construct high dynamic rang…
Asteroseismology and Interferometry
M. S. Cunha, C. Aerts, J. Christensen-Dalsgaard +22
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies…
Preparing an ESO proposal
Pierre Kervella, Paulo J. V. Garcia
Preparing observing proposals is a classical exercise in an observational astronomer's life. In this paper, we summarize the general requirements to write a good proposal for the E…
Predicted rotation signatures in MHD disc winds and comparison to DG Tau observations
N. Pesenti, C. Dougados, S. Cabrit +4
Motivated by the first detections of rotation signatures in the DG Tau jet (Bacciotti et al. 2002), we examine possible biases affecting the relation between detected rotation sign…
Near-IR [Fe II] emission diagnostics applied to cold disk winds in young stars
N. Pesenti, C. Dougados, S. Cabrit +3
We investigate the emissivity properties of the main near-IR transitions of the Fe+ ion in the conditions prevailing in the inner regions of jets from young stars, based on a simpl…
