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)?
If you could visit another planetary system while the planets are forming, would you expect to see the condensation sequence at work, or do you think that process was most likely unique to our Solar System? How do the properties of the extrasolar planets discovered so far affect your answer?
Do you expect the most planetary system in the Universe have analogs to our Solar System’s asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment?
If the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?
