 With a new image in 2014, the configuration and alignment of the dust ring and HR4796A has been nicknamed "Eye of Sauron".In 2017 a group using NASA/IRTF and Spitzer infrared spectroscopy of the infrared excess determined that the bright narrow ring is made up of very red devolatilzed cometary material, and that a second faint, hot diffuse dust component likely due to inspiralling material escaping from the ring was present close to the star and evaporating.The discovery of a complex dust structure about 1,600 AU across, enveloping HR 4796A, was announced in March 2018.
