HIP 45839 Archives

ShaneAO/ShARCS high-resolution imaging of HIP 18512 (left), ShaneAO/ShARCS imaging of HIP 45839 (center), and Keck/NIRC2 high-contrast imaging of HIP 45839 (right). Each image is oriented such that north is up and and east is to the left. HIP 18512 shows a binary at a separation of 10. ′′9 and a position angle of 12.7 ◦ . The Keck/NIRC2 imaging of HIP 45839 shows a faint source at 5. ′′3 which is not consistent with the observed RV trend and astrometric acceleration. A zoomed-in 0. ′′4 × 0. ′′4 cutout of the source is shown in the inset panel. Images are displayed with an arcsinh stretch to capture a large dynamic range (Lupton et al. 2004). -- astro-ph.EP
