Evidence for a planetary companion to HD 100546 was gathered using the UVES echelle spectrograph at the VLT in
Chile . This confirms other data indicating a planetary companion. The planets size puts it near the border between a giant planet and abrown dwarf .Protoplanetary material
Spectroscopic analysis of mid-IR data taken from OSCIR on the 4 m Blanco Telescope at
Cerro Tololo Inter-American Observatory indicates the presence of a small particles (10 - 18 ) containingsilicates .Cite journal | title = The Disk and Environment of the Herbig Be Star HD 100546 | first = C.
