A second planetesimal collision in the Fomalhaut system

Paul Kalas, Jason J. Wang, Maxwell A. Millar-Blanchaer +7

The nearby star Fomalhaut is orbited by a compact source, Fomalhaut b, which has previously been interpreted as either a dust-enshrouded exoplanet or a dust cloud generated by the…

Early High-contrast Imaging Results with Keck/NIRC2-PWFS: The SR 21 Disk

Taichi Uyama, Bin Ren, Dimitri Mawet +22

High-contrast imaging of exoplanets and protoplanetary disks depends on wavefront sensing and correction made by adaptive optics instruments. Classically, wavefront sensing has bee…
