Chapter 6, Problem 33Q

(a)

To determine

The wavelength of the emission, if the Institute of Space and Astronautical Science (ISAS) in Japan proposes to place a radio telescope at an orbit higher than that of the HALCA telescope. The astronomers propose to use this combination of telescopes to study radio emission at a frequency of $43\text{ GHz}$, using the molecule of silicon monoxide found in the interstellar clouds that form stars. Using this telescope in conjunction with a ground-based radio telescope, a 25000 km long baseline is obtainable. $\left(1{\text{ GHz =1 gigahertz =10}}^9\text{ Hz}\right)$

(b)

To determine

The angular resolution that can be achieved by assuming the baseline to be the effective diameter of a radio telescope array, if the Institute of Space and Astronautical Science (ISAS) in Japan proposes to place a radio telescope at a higher orbit than that of the HALCA telescope. Astronomers propose to use this combination of telescopes to study radio emission at a frequency of $43\text{ GHz}$, from the molecule of silicon monoxide that is found in the interstellar clouds that form stars. Using this telescope in conjunction with a ground-based radio telescope, a 25000 km long baseline is obtainable. $\left(1{\text{ GHz =1 gigahertz =10}}^9\text{ Hz}\right)$
