- Which of the following statements are TRUE about the Sun's spectrum, which is shown in this image? Brightness 2.5 3.5 0 200 Sun's Spectrum vs. Thermal Radiator of a single temperature T = 5777 K peak spectrum of Sun spectrum of T = 5777 K blackbody emission spectrum (continuum) absorption lines 400 600 800 1000 1200 1400 1600 1800 Wavelength (nanometres) 2000 The spectrum shows the presence of many sunspots. The overall shape is consistent with a continuous spectrum emitted by a blackbody. The spectrum shows that the Sun emits light of all colors equally, which is why we see it as white. The spectrum shows that the Sun emits some light in ultraviolet wavelengths. The spectrum peaks in infrared wavelengths.1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this? 2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?What are the main similarities and differences between solar physics and stellar physics? What are the advantages and disadvantages of having a star so near us? SO
- 13 What is the solar wind? (A) The uppermost layer of the Sun, lying just above the corona B A stream of charged particles flowing outward from the surface of the Sun с D The wind that causes huge arcs of gas to rise above the Sun's surface The strong wind that blows sunspots around on the surface of the SunWhat is the ultraviolet catastrophe?What is the full story of how light elements formed?
- Earth tugs the Sun around as it orbits, but it affects the radial velocity of the sun by only 0.09m/s. How large a shift in wavelength does this cause in the Sun's spectrum at 575 nm?In the Sun, how do magnetic fields manifest and what is their origin?(Answer don't copy with hand written please)As a star runs out of hydrogen to fuel nuclear fusion in its core, changes within the star usually cause it to leave the main sequence, expanding and cooling as it does so. Would a star with a radius 12 times that of the Sun, but a surface temperature 0.5 times that of the Sun, be more, or less luminous than the Sun? Show and explain your reasoning. You may assume the surface area of a sphere is A = 4πr2.
