Question

if a certain star emits most intensely in the visible region of the spectrum, a cooler star would emit mostly in what part of the spectrum

Answer 1

A cooler star would emit mostly in infrared range of the spectrum.

Emission of high temperature stars

High temperature stars like the Sun, which are approximately 6000 K at the surface, emit most of their radiation at visible wavelengths.

Emission of the cooler stars

In stark contrast to high temperature stars, the cooler stars emit most of their radiations in the infrared (IR) range.

Thus, we can conclude that,  a cooler star would emit mostly in infrared range of the spectrum.
