I’m going to take on your question, though I definitely do not claim to be smarter than you. So you might want to stop reading right here, lol!
All stars are “like” our sun in that they put out their own light because of nuclear fusion taking place in their cores. But the similarity ends there. There is a huge variance, or variability, in the population of stars out there, in their mass, temperature, size, age, etc. There are short YouTube videos that show the variance in the size of stars.
I think most if not all stars are believed to have planets. But of course, some stars might not have planets because none ever formed (hard to believe), or were swept out of existence by nearby orbiting binary companions.
There is that, too.
That explanation totally works for me. :)
“However, for hotter stars, such as the components of Spica...”
I hope these guys don’t get into trouble. I read about some boys in high school that got into trouble for ranking how hot the girls were.
