1 If you were using a telescope to study a pair of binary stars, and the telescope had an angularresolution of I arcsecond, could you resolve as two distinct objects the two stellar componentsof a binary system that had an orbital separation of 1000 AU and a distance from the Earth of500 parsecs?a) Yes. The angular separation of the binary stars would be 2 arcsecond.b) Yes. The angular separation of the binary stars would be 0.1 arcsecond.c) No. The angular separation of the binary stars would be 0.5 arcsecond.d) No. The angular separation of the binary stars would be 10 arcsecond.
