"Epsilon Aurigae, Sirius B and Valenderay were simply among the most famous examples."
-Poul Anderson, "Lodestar" IN Anderson, The Earth Book OfStormgate (New York, 1979), pp. 368-408 AT p. 386.
Here Poul Anderson seamlessly blends current cosmology with his own science fiction. Epsilon Aurigae and Sirius B are real stars. Valenderay is the Eriau name for the supernova that threatened to destroy Merseian civilization in the earlier story, "Day of Burning."
Finally, "Lodestar" is about the search for the supernova that created Mirkheim.
