Tutorial
Star A has a temperature of 5,000 K. How much energy per second (in J/s/m2) does it radiate from a square meter of its surface?
If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of
Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate from a square meter of its surface?
Part 1 of 4
The energy of a star is related to its temperature by
E = GT4
where σ = 5.67 x 10-8 J/s/m2/K4.
Part 2 of 4
To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA.

Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate onto a square meter of its surface?
Part 1 of 4
The energy of a star is related to its temperature by
E = OTA
where o = 5.67 x 10-8 J/s/m²/K4.
Part 2 of 4
To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA.

If the color of the sun's photosphere's maximum intensity light is green, is this the color we normally observe for the photosphere? Why or why not?
(I would assume it is not, but I do not know why...)

- Make a sketch of the Sun’s atmosphere showing the locations of the photosphere, chromosphere, and corona. What is the approximate temperature of each of these regions?arrow_forwardThe radius of the Sun is 0.7 million km. What percentage of the radius is taken up by the chromosphere? (Hint: Refer to Figure 8-1.)arrow_forwardFrom the information in Figure 15.21, estimate the speed with which the particles in the CME in parts (c) and (d) are moving away from the Sun. Figure 15.21 Flare and Coronal Mass Ejection. This sequence of four images shows the evolution over time of a giant eruption on the Sun. (a) The event began at the location of a sunspot group, and (b) a flare is seen in far-ultraviolet light. (c) Fourteen hours later, a CME is seen blasting out into space. (d) Three hours later, this CME has expanded to form a giant cloud of particles escaping from the Sun and is beginning the journey out into the solar system. The white circle in (c) and (d) shows the diameter of the solar photosphere. The larger dark area shows where light from the Sun has been blocked out by a specially designed instrument to make it possible to see the faint emission from the corona.
