Hello all,
Some of you may have seen or be participating in Andrew Gaspur's List of O-type stars project. With Andrew's permission, I am starting a similar project for Wolf-Rayet class stars. Andrew has kindly agreed to let me use his spreadsheet format.
Wolf-Rayet stars are among my favorite space objects. They're the hottest stellar objects, up to 200,000 kelvin; and very often are found inside planetary nebula. These incredible objects put out so much power they usually blast off much of their outer layers to form the nebula we see. They represent a late stage in the evolution of highly massive stars, usually O-type. Their massive power comes from either helium fusion or sometimes carbon-nitrogen-oxygen fusion.
There should be only around 1000 of these objects in the whole galaxy, so making a catalog won't be an endless task! Even better, many of these objects are at the heart of nebula, so we'll also be helping to build a nebula catalog.
As with Andrew's project, there is a spreadsheet for entering data on these stars, and anyone who wishes to contribute can do so. We're looking both for general data (name, spectral type), but the best data is for you to go the system itself and scan the object!
The spreadsheet can be found here: Wolf-Rayet Stars of the Milky Way
Taken from Andrew's original post:
Now the big question is: Where do I find Wolf-Rayet stars?
Since they tend to be the most (or more) massive stars in a given sector, they can usually be found in star systems with certain letter codes in them. It currently appears that all procedurally generated Wolf-Rayets are found in systems with "AA-A h" classifications. Example: Tiefua AA-A h0
There may be other code types from procedural WRs. If so, they are likely to be:
- AA-A
- BA-A
- CL-Y
- DL-Y
- EG-Y
- FG-Y
However, many of these stars are also found inside nebula! Keep your eyes out for planetary nebula, and you'll often find them inside. To find existing known WR stars - for cataloging and for traveling to find and add data - you can also use EDSM's body search feature: https://www.edsm.net/en/search/bodies
A great many of the WR stars are found in the common star catalogues: HD, HIP, BD, CSI, and GCRV.
Thank you to all who choose to contribute!
