Comment : |
The Pleiades is light up from hot blue stars, the red radiation is almost nothing, and either there is any IR radiation.
But there is one star that looks to have strong IR radiation,
see the green star where the arrow is. I come back about that one.
Update:
Now I have the information from Aladin, this is the V* SY Tau star, a long period variable star. |
