Drag the helium spectrum next to the star spectrum do some of the lines are

It sounds like you are working on comparing the spectra of helium and a star, perhaps in the context of astrophysics or spectroscopy. When you line up the helium spectrum next to the star spectrum, you would typically look for absorption or emission lines in both spectra.

1. **Helium Spectrum**: Helium's spectrum consists of distinct lines corresponding to specific wavelengths of light that are emitted or absorbed by helium atoms. These lines appear at specific intervals and are characteristic of helium.

2. **Star Spectrum**: The spectrum of a star is usually a continuous spectrum with dark absorption lines superimposed. These lines correspond to the elements present in the star's atmosphere, which absorb certain wavelengths of light.

When you drag the helium spectrum next to the star spectrum, you would focus on identifying whether the absorption lines in the star's spectrum match the emission lines from the helium spectrum. If they do match, it indicates that helium is present in the star’s atmosphere, and you can determine the relative abundance of helium and other elements based on the depth of the absorption lines.

This analysis can provide significant insights into the composition, temperature, and other physical properties of the star. If you are using software or a tool to perform this task, make sure to align the wavelengths correctly for accurate comparison.
