This is a very rough, back-of-the-envolope, calculation, so give any inforation you find that disagrees with this the benefit ofthe doubt.

Arcturus is slightly smaller (and therefore hotter) than the star you want, so let's say the surface temerature of this orange giant of yours is about 4000K. In that case, we're talking about a planet orbiting at 3.6AU (the distance required for the star to appear 8 times the diameter of the sun from the surface of the planet) receiving 43.9 times more solar radiation than Earth!

Phwor! Scorching!
