Which type of radiation would you look for in a star to demonstrate that nuclear fusion was occurring inside?
Neutrinos!
Neutrinos can freely pass through the star from the moment they are created, carrying with them information about the nuclear fusion happening in the stellar core. Nuclear reactions release energy through both neutrinos and gamma rays (technically created then a positron annihilates with an electron). Unfortunately, the gamma rays get re-absorbed and re-emitted many many times before they reach the'surface' of the star.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
