High-contrast imaging of HD 163296 with the Keck/NIRC2 L'-band vortex coronograph

We present observations of the nearby (D\(\sim\)100\,pc) Herbig star HD~163296 taken with the vortex coronograph at Keck/NIRC2 in the L' band (3.7~\(\mu\)m), to search for planetary mass companions in the ringed disc surrounding this pre-main sequence star. The images reveal an arc-like region...
