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)?
Sometime 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. (1 light-year = 9.461×10^15 m)
Note: Jupiter's Diameter dj=1.43×10^8 m
1)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.)
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.)
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_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 planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. 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.

- When astronomers found the first giant planets with orbits of only a few days, they did not know whether those planets were gaseous and liquid like Jupiter or rocky like Mercury. The observations of HD 209458 settled this question because observations of the transit of the star by this planet made it possible to determine the radius of the planet. Use the data given in the text to estimate the density of this planet, and then use that information to explain why it must be a gas giant.arrow_forwardWhile doing a transit study, you find an exoplanet around a nearby Sun-like star. The time between transits is P= 32days. During a transit, the time from first to second contact is t2−t1= 30minutes, and the time from fist to third contact is t3−t1= 5hours. The depth of the transit is δF/F= 0.01. During follow-up radial velocity measurements of the star, you find that its peak radial velocity is vr= 65m s−1. What is the radius of the planet? What is the mass of the planet? What is the semimajor axis of the planet’s orbit?arrow_forwardWhat diameter telescope is needed to resolve the separation between an Earth-like planet and its star at 550 nm if the linear separation between them is 1 AU and the star system is 1 pc from Earth?arrow_forward
