WR140 Periastron 2016-2017
Another 7.9 years have pasted and here we did cover again the periastron of the system WRC + O5 . The event has been covered through all wavelengths from radio to X- Rays, from land and from space. The periastron took place the 18th December 2016. My modest contribution,
In the optical spectra it is important to study the effect of the wave passing the CIII line due to the stellar winds collision, with the production of dust.
