Helium

Helium (from lit) is a chemical element with symbol He and atomic number 2.

Hydrogen

Hydrogen is a chemical element with symbol H and atomic number 1.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Quintuplet cluster

The Quintuplet cluster is a dense cluster of massive young stars about 100 light years from the Galactic Center (GC).

Solar luminosity

The solar luminosity,, is a unit of radiant flux (power emitted in the form of photons) conventionally used by astronomers to measure the luminosity of stars, galaxies and other celestial objects in terms of the output of the Sun.

Wolf–Rayet star

Wolf–Rayet stars, often abbreviated as WR stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of highly ionised helium and nitrogen or carbon.
