Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit
Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31
Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
CS Cha B: A disc-obscured M-type star mimicking a polarised planetary companion
S. Y. Haffert, R. G. van Holstein, C. Ginski +6
Context. Direct imaging provides a steady flow of newly discovered giant planets and brown dwarf companions. These multi-object systems can provide information about the formation…
Nonlinear wavefront reconstruction with convolutional neural networks for Fourier-based wavefront sensors
Rico Landman, Sebastiaan Haffert
Fourier-based wavefront sensors, such as the Pyramid Wavefront Sensor (PWFS), are the current preference for high contrast imaging due to their high sensitivity. However, these wav…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
Original use of MUSE's laser tomography adaptive optics to directly image young accreting exoplanets
Julien H. Girard, Jozua de Boer, Sebastiaan Haffert +8
We present recent results obtained with the VLT/MUSE Integral Field Spectrograph fed by the 4LGSF and its laser tomography adaptive optics module GALACSI. While this so-called narr…
Two accreting protoplanets around the young star PDS 70
S. Y. Haffert, A. J. Bohn, J. de Boer +5
Newly forming proto-planets are expected to create cavities and substructures in young, gas-rich proto-planetary disks, but they are difficult to detect as they could be confused w…
