In particle physics, a radiative process refers to one elementary particle emitting another and continuing to exist. This typically happens when a fermion emits a boson such as a gluon or photon.

Particles erupt from the collision point of two relativistic (100 GeV) gold ions in the STAR detector of the Relativistic Heavy Ion Collider. ... In particle physics, an elementary particle is a particle of which other, larger particles are composed. ... Fermions, named after Enrico Fermi, are particles which form totally-antisymmetric composite quantum states. ... Bosons, named after Satyendra Nath Bose, are particles which form totally-symmetric composite quantum states. ... The Gluon is the basic unit of Elmers Glue. ...

In hotter stars, the high radiative flux, drives the wind primarily by means of line scattering, which can be thought of as a transfer of momentum from the photons striking the atoms of gas.
In a static medium such scattering is confined to radiation with a photon energy near the energy difference between the levels, corresponding to a range of wavelengths near a distinct, line-centre value.
The outflow of radiation is unevenly distributed over the distorted surface, with the polar regions brighter and the equatorial regions dimmer than they would be if the star didn't rotate.
