H5.
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)?
While looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.
One way that astronomers detect planets outside of our solar system (called exoplanets) is commonly referred to as the radial velocity method. This relies on the __________ ___________ to cause shifts in the spectral lines of stars as the stars perform tiny orbits around the center of mass of the host star and its orbiting planets. Those tiny orbits cause the stars to periodically (and therefore predictably) move closer to and further away from our solar system. Luckily, this method only relies on the motion of the star; its physical distance from us does not impact the resulting shifts.

- Which of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. For a telescope, increasing fe will decrease the actual size of the image seen by the person looking through the telescope. In crown glass, the index of refraction for red light is 1.512 and for orange light it is 1.514. Thus in crown glass, red light is faster than orange light. If unpolarized light is incident on a polarizer, 50% will pass through. The glasses for nearsighted people create real images for them to see. The smaller the diameter of an optic is, the larger the minimum angle it can discern is.arrow_forwardSometime around 2022, astronomers at the European Southern Observatory hope to begin using the E-ELT(European Extremely Large Telescope), which is planned to have a primary mirror 42 m in diameter. Let us assume that the light it focuses has a wavelength of 550 nm.

(Express your answer to two significant figures.) 2)What is the most distant Jupiter-sized planet the telescope could resolve, assuming it operates at the diffraction limit? (Express your answer to two significant figures.) 3)The nearest known exoplanets (planets beyond the solar system) are around 20 light-years away. What would have to be the minimum diameter of an optical telescope to resolve a Jupiter-sized planet at that distance using light of wavelength 550 nm? (Express your answer to two significant figures.)arrow_forwardWhich of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. The reason astronomers want telescopes with large primary mirrors is to gather as much light as possible. In crown glass, the index of refraction for red light is 1.512 and for yellow light it is 1.518. Thus in crown glass, red light is slower than yellow light. If the axes of two polarizers are anti-parallel to each other, then no light will get through. The glasses for nearsighted people create real images for them to see. The larger the diameter of an optic is, the smaller the minimum angle it can discern is.arrow_forward

Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…arrow_forwardConsider the attached light curve for a transiting planet observed by the Kepler mission.
