The status of the system as a strong nonthermal, variable
radio source, as well as an extremely bright (for a WR star) X-ray source
makes WR140 an ideal laboratory for studying the properties of hot stellar winds. The almost perfectly phase-dependent
behavior of the system in radio and X-rays is remarkable.
The system has a relativ long period and periastron passage. That means professional astronomers
have problems to obtain a lot of data during periastron. Due to its brightness amateurs can obtain reasonable data
and WR 140 gives a good oportunity to collaborate with the pro's.
We are looking for interested amateur spectroscopists for data contribution.
Don't hesitate to give information about your spectra and discuss results in our WR140-Forum.
