SOAR observations confirm a white dwarf so cool that its carbon has probably crystallized to a giant diamond

This image (left), taken in visible light at the SOAR telescope (right), shows the field of the pulsar/white dwarf pair. There is no evidence for the white dwarf at the position of the pulsar in this deep image, indicating that the white dwarf is much fainter, and therefore cooler, than any such known object. The two large white circles mask bright, overexposed stars. These results are presented in a recently published paper led by Dr. David Kaplan (UW-Milwaukee)
