Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations
M. N'Diaye, A. Vigan, B. Engler +7
Over the past decade, the high-contrast observation of disks and gas giant planets around nearby stars has been made possible on ground-based instruments using extreme adaptive opt…
WST -- Widefield Spectroscopic Telescope: design of a new 12m class telescope dedicated to widefield Multi-object and Integral Field Spectroscopy
P. Dierickx, T. Travouillon, G. Gausachs +12
The Wide-Field Spectroscopic Telescope (WST) is a concept for a 12-m class seeing-limited telescope providing two concentric fields of view for simultaneous Multi-Object Spectrosco…
WST -- Widefield Spectroscopic Telescope: addressing the instrumentation challenges of a new 12m class telescope dedicated to widefield Multi-object and Integral Field Spectroscopy
David Lee, Joel D. R. Vernet, Roland Bacon +23
WST - Widefield Spectroscopic Telescope: We summarise the design challenges of instrumentation for a proposed 12m class Telescope that aims to provide a large (>2.5 square degree)…
SPHERE RefPlanets: Search for epsilon Eridani b and warm dust
C. Tschudi, H. M. Schmid, M. Nowak +35
We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…
