It's part of my evil nature to digress into seemingly unrelated topics!

Earth-like planet, with water, around red dwarf Gliese 581? - REB - 4/24/2007 7:31:46 PM
- Are we *sure* it'd have volatiles? - dtb - 4/26/2007 1:13:42 PM
  - No such thing as sure - nick hoffman - 4/26/2007 11:37:36 PM
- It's actually has a diameter 50% larger than our world. - Jacob Samorodin - 4/25/2007 11:16:43 PM

      - very interesting... Now we need a imaging telescope that can tell us more! - The Artist formerly known as Scott Evil - 4/26/2007 1:40:37 PM

        Good point but - M.A.E. - 4/26/2007 2:31:25 AM

        Speaking of a moon- could part of this planet's calculated mass be a moon? - REB - 4/26/2007 2:34:40 PM
        
        Not 4 Earth masses- 5 Earth masses. - REB - 4/26/2007 2:57:26 PM
        
        I would love to see a true binary-planet... Where two relatively equal planets are sharing the same center of gravity. - The Artist formerly known as Scott Evil - 4/26/2007 4:25:03 PM
        
        I wonder what it would have been like to have Venus as our moon. - REB - 4/26/2007 9:57:49 PM
        
        Very Good point! - The Artist formerly known as Scott Evil - 4/26/2007 2:50:57 PM
        
        Good detective work. You were correct! - ER - 4/25/2007 3:13:11 PM

    - re: The flares could themselves result in "seasons" on such a planet. - The Artist formerly known as Scott Evil - 4/25/2007 2:44:07 PM
      - Interesting... - nick hoffman - 4/25/2007 11:07:18 PM
        
        I've always thought of seasonality as being critical to drive evolution. - The Artist formerly known as Scott Evil - 4/26/2007 3:26:56 AM

        Well Evolution Requires Either Genetic Drift Or Selective Pressure - M.A.E. - 4/26/2007 2:07:13 PM
        
        Getting wiped out can be good for evolution. - The Artist formerly known as Scott Evil - 4/26/2007 4:40:25 PM
      - Donâ€™t Red Dwarfs flair when they are young and calm down as they get older? - REB - 4/25/2007 2:48:57 PM
        
        Flares last minutes, maybe an hour or so (n/t) - phil - 4/25/2007 2:52:33 PM
        
        I mean a Red Dwarfâ€™s Flare frequency goes decreases as the star ages. - REB - 4/25/2007 2:55:23 PM
        
        rI'm specificly referring to red dwarf flare times (n/t) - phil - 4/25/2007 2:59:20 PM

        Tides - phil - 4/25/2007 2:58:39 PM
        
        Not sure about that... - TB - 4/25/2007 2:34:07 PM
        
        I think it would depend on the specific make-up of the planet and it's atmosphere (if any) - The Artist formerly known as Scott Evil - 4/25/2007 2:46:52 PM
        
        You're right about the tides, senior moment on my part. - ER - 4/25/2007 2:44:57 PM

  - I got the size wrong. This planet is 50% larger than the Earth. - REB - 4/24/2007 9:38:30 PM
    - 2.2Gs at 5 Earth masses and 1.5 Earth radii - phil - 4/24/2007 9:50:09 PM
      - Thanks Phil - Peter Bruener - 4/25/2007 5:03:02 AM
        
        AP says 1.6G; I don't get it (n/t) - phil - 4/25/2007 4:01:24 PM
        
        Either way it would be a great place to train athletes (n/t) - FrankC - 4/26/2007 9:43:21 PM
        
        That seems high. Jupiter is something like 2.3-2.4 with over 300 times the mass of Earth. (n/t) - REB - 4/25/2007 4:17:52 PM
        
        Huge Difference In Density - M.A.E. - 4/25/2007 9:27:29 PM

        They Don't - M.A.E. - 4/26/2007 2:17:47 AM
        
        Radius - depends on density which depends on compositionj which depends on.... - n - 4/25/2007 11:24:02 PM
