Chapter 18, Problem 4P
If you observe light reflected from Saturn’s rings, you should see a redshift at one edge of the rings and a blueshift at the other edge. If you observe a spectral line and see a difference in wavelength of 0.0560 nm between opposite edges of the rings, and the unshifted wavelength (observed in the laboratory) is 500. nm, what is the orbital velocity of particles at the outer edge of the rings? (Hint:
Use the Doppler shift formula in Reasoning with Numbers 6-2.)

- If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in nm) should you expect between the opposite edge of the rings? (Hint: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity and the formula for the Doppler shift.) _______ nmarrow_forwardJupiter radiates more energy than it receives from the Sun by 8.7 x10-10 LO.

- If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in my) should you expect between the opposite edges of the rings? (Hint: the radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity) _______ nmarrow_forwardA certain binary system consists of two stars that have equal masses and revolve in circular orbits around a fixed point half-way between them. If the orbital velocity of each star is v=186 km/s and the orbital period of each is 11.3 days, calculate the mass M of each star. Give your answer in units of the solar mass, 1.99×1030 kg (e.g. if each planet's mass is 3.98×1030 kg, you would answer "2.00").arrow_forwardH5. A star with mass 1.05 M has a luminosity of 4.49 × 1026 W and effective temperature of 5700 K. It dims to 4.42 × 1026 W every 1.39 Earth days due to a transiting exoplanet. The duration of the transit reveals that the exoplanet orbits at a distance of 0.0617 AU. Based on this information, calculate the radius of the planet (expressed in Jupiter radii) and the minimum inclination of its orbit to our line of sight. Follow up observations of the star in part reveal that a spectral feature with a rest wavelength of 656 nm is redshifted by 1.41×10−3 nm with the same period as the observed transit. Assuming a circular orbit what can be inferred about the planet’s mass (expressed in Jupiter masses)?arrow_forward
