Welcome to Peredur Williams's home page
The most recent periastron passage in the WR140 system occurred
in 2009, stimulating an intensive multi-wavelength observing campaign to study

rapidly on account of the high orbital eccentricity. Some
from the 2009 Campaign were reported in July 2010 at the 39th Liège
