A3_3_Detection bias in the search for extrasolar planets

Owen Littlejohns, Kathryn Hill, Ryan Laird


The detection of extra solar planets is discussed, with particular emphasis laid upon the radial velocity method. An expression for how detectable a planet is based on planetary mass is derived. To illustrate the difficulties in finding terrestrial planets, this formula is applied to the Earth-Sun system to find the fractional change in wavelength.
