The James Webb Space Telescope, the replacement for the
Hubble Telescope, will have a diameter (aperture) of 6.5 m.
Calculate the minimum angular separation that two stars could
have and still be resolvable.
If two stars have a magnitude difference of 8.6 what will be its intensity ratio?
Two identical stars are moving in a circular orbit around one another with an orbital separation of 2 AU. The system lies
200 light-years from Earth. If we happen to view the orbit head-on, how large a telescope would we need to resolve the
stars, assuming diffraction-limited optics at a wavelength of 2 μm?
