The Sirius System and its Astrophysical Puzzles: Hubble Space Telescope and Ground-Based Astrometry

evidence

Supports the identification of Sirius B as the first observed white dwarf and the Stefan-Boltzmann radius estimate of about 0.008 solar radii at roughly 25,000 K. Neither source was fetched; the 31 January 1862 discovery date and the 18.5-inch aperture come from reference summaries.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
