... there is no unanimity about how to raise mass from a photosphere out to the radius where dust can form, nor, in particular, is ... I have found instances of both. What of a fundamental momentum source for lifting mass away from the photosphere? ...
... stars, observed thermal radiation from the neutron star surface can be used in combination with a precise distance to constrain the `size' of the 1 neutron star photosphere, and thus the Equation of State of matter at extreme pressures and densities ...
... Besides intercepting much of the radiation from the photosphere, which is then reradiated as black-body radiation in the mid-IR, dust grains also protect outflowing molecules against rapid degradation by interstellar UV. ...

... This is comparable with a wind travel-time (t c/2 ve) ~ 770 yr from the photosphere to the 1612MHz emitting region, which derives from the phase-lag between the blue and red peaks of WX Psc (van Langevelde et al. ...
... on La Palma, enabling it to study the detailed interaction of "fibril" magnetic fields with turbulent plasmas in the solar photosphere, the root of the chromospheric and coronal activity of higher layers that is so conspicuous at ultraviolet and X-ray ...

... believed to arise from the rupture of a stressed magnetic structure which by magnetic buoyancy is forced upwards through the photosphere into the corona/transition region where reconnection of magnetic field occurs followed by considerable energy release ...
