Radiative levitation
text:
Radiative levitation is the name given to a phenomenon that causes the spectroscopically-derived abundance of heavy elements in the photospheres of hot stars to be very much higher than solar abundance or than the expected bulk abundance; for example, the spectrum of the star Feige 86 has gold and platinum abundances three to ten thousand times higher than solar norms. The mechanism is that heavier elements have large photon absorption cross-sections when partially ionized, so efficiently absorb
