The answer is Protostar.

Here's the step by step explanation:

1. The second stage in the formation of a star involves the accumulation of gas and dust in a region of space, creating a dense core.

2. This core, under the influence of its own gravitational pull, continues to attract more matter from its surroundings.

3. As more and more matter falls into the core, the pressure and temperature at the center increase.

4. This stage of a star's life is known as the Protostar stage. It is during this stage that the core of the star starts to heat up due to the increasing pressure from the overlying layers of gas and dust.

5. Scientists can detect protostars using infrared telescopes. This is because protostars, while not yet hot enough to emit visible light, do emit infrared radiation due to the heat generated by the gravitational compression of the gas and dust.

6. Therefore, the blank in your sentence should be filled with "Protostar". The sentence should read: "Second Stage: At the center of the swirling gas and dust, heat and pressure build up inside of the Protostar. Scientists find this stage using infrared telescopes."
