... For smaller epochs the temperature of the ejecta is too high, or the photosphere must be at velocities so large that there is not enough material above it to form strong absorption lines. ...
... These components are constructed by averaging Fe i 6302 е magnetically sensitive absorption line profiles output from detailed radiative transport calculations of the solar photosphere. ...

... circumstellar gas they detect is transported from the photosphere of the star, and so one possibility would be that these, together with localized heating, lead to less opaque channels through which the emission from the photosphere can escape ...

... from which photons can escape (the photosphere) is a substantial fraction of the ... Observations at different wavelengths probe different layers within the photosphere. ...
... Smaller areas for the hotspots imply that their temperatures must be greater than T1290 , and so the bright features do trace pockets of hot gas within the deeper photosphere. ...
