Chapter 3, Problem 6P
(3.6) Gliese 581e is an exoplanet with a mass of 1.9 Earths that orbits a red dwarf star at a distance of 5 × 1010 m (0.33 AU). If its orbital period is 124 days, find the mass of the star in kg. Divide your answer by the Sun’s mass to see how much more or less massive the star is than our Sun.

A 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").
Pluto is considered a binary dwarf planet system
with its companion Charon. Pluto has a mass of 1.303 x
1022 kg and mean radius of 1188.3 km. Charon has a mass
of 1.586 x 1021 kg and mean radius of 606 km. The binary

system has a semi-major axis with the sun of 39.482 AU
and there is an average distance of 19,591.4 km between
the two dwarf planets. What is the system's center of mass
with respect to Pluto, and why does this mean that Charon
is a binary system and not a moon?

- A planet (in another galaxy) takes 5 000 Earth days to complete one full revolution around its own star (not the Sun). It is exactly as far away from its star as Earth is to its own Sun. Draw a FBD, then determine how many times more or less massive this star is than our sun (in other words, give a factor of mass, e.g “5x larger” or “5x smaller”)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_forwardThe two planets orbiting the nearby star Gliese 876 are observed to be in 2:1 resonance (i.e., the period of one is twice that of the other).

Check your answer for correctness.arrow_forwardDetermining the orbit of the two stars of Kepler-34, also called A and B. These two stars together are called a binary. A) Assume that star A has a mass of 1 solar mass and star B also has a mass of 1 solar mass. The semi major axis is 0.23 AU and the eccentricty is 0.53. What is the orbital period of the stellar A-B binary in days? Ignore the (much less massive) planet and focus on the orbit of the binary. B) Now let's consider the orbit of the planet, called "b". Since the planet orbits some distance away from the stars, it is an acceptable approximation to pretend like the stellar binary is like a single star with a mass that is the sum of the masses of stars A and B and that the mass of planet "b" is very small, calculate the semi-major axis in AU of the planet's orbit with a period of 289 days. (note: I think for this problem you are supposed to use Newton's version of Kepler's third law P2= 4π2/G(M1-M2)x a3 but, I'm not sure if that's the right thing to do). 1 solar mass= 2 x…arrow_forward
- Suppose you observe a binary system containing a main-sequence star and a brown dwarf. The orbital period of the system is 1 year, and the average separation of the system is 1 AU . You then measure the Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf, finding that the orbital speed of the brown dwarf in the system is 23 times greater than that of the main-sequence star. How massive is the brown dwarf in kg?arrow_forwardThe orbital radius of one exoplanet is 5.34 X 1011 m, with a period of 1270 Earth days.

- The tidal force is a differential force: dF/dr, which is the difference between the force at one distance and the force at another. If dr happens to correspond to, say, your height, then the tidal force is the difference in gravity felt by your head and by your feet. This amounts to a stretching force, since one end is pulled harder than the other end. Calculate the tidal force experienced by your body at the surface of a neutron star. Assume that the neutron star has a mass of 1.5 solar masses and a radius of 10 km. Assume that your mass is 100 kg and that your dr (height) is 2 m when standing and 0.5 m when prone. What is the tidal force when you are standing? What is the tidal force when you are prone? Based on the above, what do you recommend for minimizing the tidal force?arrow_forwardKepler’s third law says that the orbital period (in years) is proportional to the square root of the cube of the mean distance (in AU) from the Sun (Pa1.5) . For mean distances from 0.1 to 32 AU, calculate and plot a curve showing the expected Keplerian period. For each planet in our solar system, look up the mean distance from the Sun in AU and the orbital period in years and overplot these data on the theoretical Keplerian curve.arrow_forwardAn exoplanetary system has two known planets. Planet X orbits in 290 days and Planet Y orbits in 145 days. Which planet is closest to its host star?
