Johannes A. van Paradijs (9 June 1946 – 2 November 1999) was a Dutch high-energy astrophysicist. He is best known for discovering the first optical afterglow of a gamma-ray burst, GRB 970228, in February 1997, together with two of his students, and for establishing that gamma-ray bursts are extragalactic events.

Research

Van Paradijs determined the first mass of a neutron star, the X-ray pulsar Vela X-1 in 1975. In 1978 he showed that X-ray bursters are neutron stars in binary systems. Using spectroscopic mapping, he was the first to spatially resolve an accretion disk.

Academic career

Van Paradijs obtained his PhD at the University of Amsterdam, Netherlands, in 1975, working on cool giant stars. Afterwards he started working on X-ray binaries. In 1988 he was appointed full professor at the University of Amsterdam, and later he worked part-time at the University of Alabama in Huntsville, U.S. He published over 400 scientific papers, including many with long-time collaborator Walter Lewin of MIT.

The minor planet 9259 Janvanparadijs was named after him.
