    Solar flares triggering seismic events

    Well, given the way earthquakes work, someone will eventually argue that some butterfly landing on a specific rock caused the whole thing. On an unrelated note, I have spent most of this morning convincing people that 'an unusually low lunar perigee' is not the cause for the disaster in Japan...

    The eccentricity of binary stars' orbits

    Well, the planet's orbit will have to be stable enough to be an ellipse, which assumes it's quite far away from the apoapsis distance of the stars (AFAIRemember >12*a). Anyway, a circumbinary orbit should have it's Kepler elements defined w.r.t the binary system's barycenter.

    Total radiation flux from a star

    Any way I can realistically quantify this given the specs for a star and a distance? Something that wouldn't be pure guesswork? I understand there will be a lot of fudge-factors and unknown constants but the general trend will suffice. Heck, even a general 2D diagram will do. I guess what I...

    I Why is there a universal speed limit, c, and why is it what it is?

    Well, like bcrowell was saying, when asking 'why' questions, you inevitably end-up with a sequence like: Why is 'A' true? Because 'B' is true. Well, then why is 'B' true? Because 'C' is true. Well, then why is 'C' true? ... and you can do this for a long time until the answer comes back as...

    Total radiation flux from a star

    Hmm...enlightning! So the Stefan Boltzmann should account for most of the radiation coming out from a star? How about estimating the magnetic field strength? I would assume that depends on the rotation of the star? Is there any current way of determining the rotation of observable stars? Or...

    Total radiation flux from a star

    Hi all ! I'm looking around the net to find good resources on how to compute total radiation flux from a given star at a given orbiting distance. Ideally I'd like to get not just the W/m2 of the star, but also the expected high-energy radiation, thermal, solar wind pressure.. well, the...
