James Michael Lattimer (born April 12, 1950 in Marion , Indiana ) is an American astrophysicist .

Life

Lattimer graduated from the University of Notre Dame with a bachelor's degree in 1972 and received his PhD in astrophysics from the University of Texas at Austin in 1976 with a dissertation on the collision of neutron stars and black holes. He was a post-doctoral student at the University of Chicago and the University of Illinois at Urbana-Champaign. In 1979 he became Assistant Professor and in 1988 Professor at the State University of New York at Stony Brook (SUNY). In 2013 he became a Distinguished Professor there.

In 1985/86 he was visiting professor at Nordita and from 1982 to 1984 Sloan Research Fellow . In 1999 he was a Guggenheim Fellow , in 1985 he received the Ernest Fullham Award and he is a Fellow of the American Physical Society . In 2013 he was a Yukawa visiting professor in Kyoto.

He worked on supernovae and developed equations of state for very hot and dense matter, as required in simulation calculations for supernovae and neutron stars. A joint work with Hans Bethe , Gerald Brown and JH Applegate from 1979 was important here. Together with FD Swesty, he then developed widely used, thermodynamically consistent state equation tables for use in simulations on high-performance computers. They were checked with data from nuclear physics experiments and observations of neutron stars (such as mass, radius).

In 1986 he and A. Burrows simulated the formation of new neutron stars in good agreement with observations made at SN 1987A . With Madappa Prakash and others he investigated the direct Urca cooling process (cooling of neutron stars and white dwarfs through neutrino emission), found a relationship between the equation of state of nuclear matter, neutron star mass and neutron star radius and developed the paradigm of minimal cooling for the thermal evolution of neutron stars.

In 2015 he received the Hans-A.-Bethe-Preis for outstanding work that combines the observation of supernovae and neutron stars with neutrino emissions and the equations of state of matter beyond the density in nuclei (laudation).
