We use observations with the infrared-optimized Magellan Adaptive Optics (MagAO) system and Clio camera in 3.9 μ m light to place stringent mass constraints on possible undetected companions to Sirius A. We suppress the light from Sirius A by imagin

Publikováno v: Techniques and Instrumentation for Detection of Exoplanets X.

The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. A major limitation is the temporal error of the adaptive optics systems. The temporal error can be reduced with predictive control. We use a line
