In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 1/9 the distance of Mercury from our Sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). a. What is the mass of the star? Express your answer in kilograms and as a multiple of our Sun's mass. b. How fast (in km/s) is this planet moving?

A. Use the definition of the center of mass to determine the maximum “wobble” velocity of a star of mass M caused by a planet of mass m orbiting at a distance r from the star with a period T. B. Thanks to Kepler, we know that the mass, period, and distance of an orbiting object are actually related. Use Newton’s version of Kepler’s Third Law to determine the maximum “wobble” velocity in terms of M, m, and r.

Nothing can escape the event horizon of a black hole, not even light. You can think of the event horizon as being the distance from a black hole at which the escape speed is the speed of light, 3.00×10^8 m/s, making all escape impossible. What is the radius of the event horizon for a black hole with a mass 3.5 times the mass of the sun?

3 O с Which of the following is a reason that astronomers have not found giant planets with the orbit of Neptune around other stars? our theories suggest that orbits as far away from a star as Neptune are never stable (and the presence of Neptune in our own solar system is a big mystery) the method we are using to find planets currently can only reveal low-mass planets, while we expect high-mass planets at the orbit of Neptune we have already found several planets as far from their stars as Neptune is from the Sun At the distance of Neptune's orbit, it takes 165 years to go around the Sun; getting information about just one cycle of such a planet's orbit around another star would take astronomers 165 years O at the orbit of Neptune, only very low-mass planets (smaller than Mercury) can form F3 $ 4 R (1) F F4 V DII % 5 T Q Search F5 G 6 B F6 Y = 8 0 H F7 & 7 U N PrtScn J F8 W 8 Home 1 W F9 M 9 K End O F10 ) PgUp 0 L
