Figure 72: Relationship between the effective surface temperature , as measured by an observer
at infinity, and the local temperature at the bottom of the heat-blanketing envelope, (at
). Calculations performed for the ground-state (Fe) and partly-accreted envelopes
of mass . Numbers indicate for a star with surface
gravity (in units of 1014 cm s–2). Symbols in parentheses indicate chemical composition
of accreted envelope.
