Gomez's Hamburger, also known as IRAS 18059−3211 or Gomez's Whopper, is an astronomical object believed to be a young A-type star surrounded by a protoplanetary disk. However, recent results suggest that this object is a young star surrounded by a protoplanetary disk, at a distance of about 900 light-years away.
It was discovered in 1985 on sky photographs obtained by Arturo Gómez, support technical staff at the Cerro Tololo Inter-American Observatory near Vicuña, Chile. The photos suggested that there was a dark band across the object, but its exact structure was difficult to determine because of the atmospheric turbulence that hampers all images taken from the ground. The star itself has a surface temperature of approximately 10,000 K.
The "buns" are light reflecting off dust. A disk of dust seen nearly exactly edge-on obscures the star and produces the dark band in the middle, the "burger". Protoplanetary disk can however form disk fragments that are gravitationally bound and can mimic protoplanets. In the case of GoHam b it is not clear if it is a protoplanet or just a disk fragment.
