Answer to Problem 1VSC

Solution:

10 Solar unit.

Explanation of Solution

Introduction:

Sub giant is the phase where star appears more brighter than the normal sub sequence star in the same spectral class.

In the H-R diagram shown in the figure luminosity corresponding to Sun’s subgiant stage is 10 Solar unit.

Hence, approximate luminosity corresponding to subgiant stage is 10 solar unit.

Conclusion:

Observing the H-R diagram shown the luminosity corresponding to subgiant stage is 10 solar unit.
