Homework Statement
a) The peak intensity of light from the Sun occurs at a wavelength of 500 nm. Astronomers discover a nearby star, “Nus”, which is the same size and mass as the Sun, but has a peak wavelength of half this value. Is Nus hotter or colder than the Sun and by how much?
Nus is discovered to have eight planets in orbit. These eight planets are separated from Nus at precisely the same distances as the planets in our own Solar System are from the Sun. Do you expect that this system will be comprised of greater, fewer or the same number of giant planets as the Solar System, and why? [6 pts] c) The third planet from Nus, Htrae, has a single large moon, Noom. Astronomers learn that the Noom has a low density, has plenty of volatiles and that Htrae is spinning extremely rapidly. Based on this information, what is the most favorable hypothesis explaining the origin of Noom?[/B]
Im currently working on part a and I think I came up with 11,700 kelvin...
I would say that the system will be comprised of the same number as the solar system due to the fact the gas giants would be beyond the frostline where the suns heat would start to diminish, kind of like in our solar system. The heavier elements like rock and metal will stay inside the frost line and that might even lead to more terrestrial-like planets in Nus' system, but the lighter elements like hydrogen and helium are captured by the planets with enough mass to do so outside of the frostline.
Anyone want to correct me?
Noom has a lower density because the impact of giant protoplanetary collision gouged out the outer crust and mantle, and didn’t eject so much of the Htrae's iron core.The huge cloud of ejected debris coalesced into the Noom. The object that collided with Htrae mustve been huge and abundant in volatiles, hence the traces in its composition.
Is it safe to say the fast spinning of Htrae has to do with the the size of the object that collided with it?
