Jim Lattimer and coworkers found that the temperature of a neutron star in our Galaxy is dropping faster than can be explained
by standard cooling theories, matching researchers' expectations for a neutron star on its way to superfluidity. The
results are published in Phys. Rev. Letters and featured in Nature.
Cassiopeia A is 11,000 light years from Earth and at 330 years old it is the youngest neutron star known in our Galaxy.
All four authors of the Physical Review Letters paper have significant ties to Stony Brook University. Dany
Page, of the National Autonomous University in Mexico, received his Ph.D. from SBU in 1989. Co-author Madappa Prakash, of
Ohio University, is a former SBU faculty member. Andrew Steiner, of Michigan State University, received his Ph.D.
from SBU in 2002.
