Work

Neutron-star temperatures reveal the properties of ultradense matter that cannot be reproduced in terrestrial laboratories.

Tsuruta developed early theoretical models for how young neutron stars cool through neutrino emission and surface radiation.

Her work made thermal observations of compact stars a probe of nuclear matter and stellar interiors.
