HD 100546 b is the largest exoplanet known.
Discovery
[edit]Evidence for a planetary companion to HD 100546 was gathered using the UVES echelle spectrograph at the VLT in Chile.[4] This confirms other data indicating a planetary companion. HD 100546 b might be the largest exoplanet discovered with a size of planet and surrounding disk[2] of around 6.9 RJ; the planet's size puts it near the border between a large planet and a brown dwarf.[1][4]
However, the position where HD 100546 b was detected was inside compared with the gap between the inner and outer disks, and outside compared with the central cavity, so the validity of the planet was shown from the characteristics of the star disk. There was a discrepancy with the discussion. As a result of further detailed observation of the position where HD 100546 b was detected, the light source identified as HD 100546 b appeared to be a point light source in the analysis under specific conditions, but in many cases it became a more diffuse structure.
