Hi,
If you don't already know me, I am Simfishy, and am new to the forum. I am only 14 year old, and an amateur in the field of Science; so I don't know very much about many of the more complex fields. However, I will try to contribute to the forum with what I know, and if I am doing something that you don't all like, then feeel free to send me a private message! I do have experience forumming n other forums (especially HeavenGames), so my behavior isn't too eccentric, but might not necessarily be appropriate enough yet for this forum. Are there any newbie guidelines that many newbies overlook that I should pay meticulous attention to?
By the way, I love to ask questions; so please be prepared to answer them for me! Thanks! I'll try to be as much of a amicable newbie as possible! :)
Now, to my question.. What do you think is the probability of Betelgeuse exploding in a supernovae in the near future? While Betelgeuse isn't an extreme Cepheid variable yet, its magnitude does vary a bit, and it's only going to get more volatile with time. Additionally, if it does explode in a supernovae, then what do you think the effects are going to be for us? It is only 500 light years away, but violent supernovae explosions can release a burst of radiation that could still be potentially dangerous to life.
Also, how does Betelgeuse compare in mass to other red supergiants, like Antares or Eta Carinae? Would an supernovae of Betelgeuse pale in comparision to the supernovae of other red supergiants; or would it be more magnificent? I don't think it would be as magnificent as the supernovae observed in 1987 would be, but Betelgeuse's proximity does give me the shivers. If Betelgeuse exploded, do you think that the core would become a neutron star?
----------------
Another question: Are blue, yellow, and white supergiants nearing the end of their lives, or are they young stars that are eventually going to turn into red supergiants like Betelgeuse as they run out of fuel in their cores? They're brighter than many main sequence stars, but also cooler. FOr instance, would do you think would be the fates of stars like Rigel, Polaris, etc?
----------------
Now, the last question...
I do know that stars like the Sun or Alpha Centauri A will turn into red giants when they're old like Capella, but not necessarily supergiants like Antares. However, what would be the fate of white stars more massive than the sun in the main sequence, like Sirius, Mizar, or Vega? Would they become supergiants, or would they just be giants more massive than the sun? Would only the very bright main sequence stars like Spica, Mintaka, Alnilam, and Alnitak became supergiants?
Your responses will be greatly appreciated!
