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…

Atmospheric Temperature Inversions and He I 5876 Core Profile Structure in White Dwarfs

Beth Klein, Simon Blouin, Diego Romani +7

We report distinctive core profiles in the strongest optical helium line, He I 5876, from high-resolution high-sensitivity observations of spectral type DB white dwarfs. By analyzi…

The Chemical Composition of an Extrasolar Kuiper-Belt-Object

S. Xu, B. Zuckerman, P. Dufour +3

The Kuiper Belt of our solar system is a source of short-period comets that may have delivered water and other volatiles to Earth and the other terrestrial planets. However, the di…
