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 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star? Express your answer (a)in kilograms and (b)as a multiple of our sun's mass. |

Astronomers discover an exoplanet, a planet orbiting a star other than the Sun, that has an orbital period of 4.01 Earth years in a circular orbit around its star, which has a measured mass of 3.97X10^30. Find the radius of the exoplanet's orbit.

In July of 1999 a planet was reported to be orbiting the Sun-like star Iota Horologii with a period of 320 days. Find the radius of the planet’as orbit, assuming that Iota Horologii has the same mass as the Sun. (This planet is presumably similar to Jupiter, but it may have large, rocky moons that enjoy a relatively pleasant climate.)

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

In Astronomy we often deal with distances, or lengths, that range form the very small to the very large. For instance The size of a nucleus is roughly 0.000, 000,000,000,001 meters and the distance to the nearest star is roughly 700,000,000,000 meters. We will talk about these numbers using scientific notation where each zero is counted as ten raised to an exponent equal to the number of zeros. Le the size of a nucleus is 1 x...
