Thanks
I would love to know what spectral classes they are going to be.
I choose an orange-brown color to highlight the question from sym666, because I suspect that they are going to be quite small and cool stars that emit orange light. I believe they are going to be small simply because most stars that are already fully formed in the galaxy are small and cool, and also low-mass star formation is so much more common in the Milky Way than high-mass star formation. Also, when high-mass star formation occurs, it appears that many small stars form for every big and massive one.
The Sun adn 61 Cygni. Illustration: RJHall.
But at least it looks as if one of the stars is going to be bigger than the others, and two of the stars - those that are very close together - look like they are going to be considerably smaller. Perhaps the biggest star will be spectral class K, and the two others will be M-class dwarfs?
The picture at left by RJHall shows a size and color comparison between the Sun and the K-class components of
61 Cygni. I must point out that K-class stars are most definitely not as red as the picture suggests - they are in fact not red at all, but yellow-orange - and not even M-class stars are that red. Only
carbon stars can be that red, and not even all carbon stars, either.
But I like the image. I think the triple star in today's APOD may grow into adulthood to become
something like that.
