Robert C. Duncan (astrophysicist)
Robert C. Duncan (born September 2, 1956 in Pensacola , Florida ) is an American astrophysicist. He is at the University of Texas at Austin (and its McDonald Observatory ).
Duncan received his PhD in astrophysics from Cornell University in 1986 (Dissertation: Topics in the theory of neutron star cooling).
In 1992, together with Christopher Thompson , he developed the Magnetar model (pulsars with extremely high magnetic fields) of the Soft Gamma Repeater (SGR).
In 2003 he and Thompson and Chryssa Kouveliotou received the Bruno Rossi Prize for their work on magnetars.
According to Duncan and colleagues, a particularly strong eruption of the SGR 1806-20 magnetar on December 27, 2004 shows a similarity to brief gamma-ray flashes (lasting less than two seconds).
