Stellar evolution test review study guide

A nebula that is a dust cloud that obscures or hides light coming from behind it.

​

• planetary nebula

• Dark nebula
• Balmer lines
• absorption spectra

A nebula that produces its own light due to bright stars exciting particles within the cloud.

• dust lanes

• hydrogen

• emission nebula

• 21 cm lines

This type of nebula is simply scattering blue light emitted by a local star, but not receiving enough energy to excite their particles.

• supernova remnant

• reddening

• reflection nebula

• helium

A nebula produced from the death of a sun-like star (0.8 to 3 solar masses).

• planetary nebula

• Balmer lines

• absorption spectra

• dark nebula

A star-forming dust cloud.

• black body curve

• bluing

• stellar nebula

• doppler shifts

A non-typical nebula produced from the explosion of a massive star.

• supernova remnant

• reddening

• reflection nebula

• helium

What happens to light when passing through dust clouds?

• supernova remnant

• reddening

• reflection nebula

• helium

Apparent changes in the wavelength of light seen due to the movement of the source.

• black body curve

• bluing

• stellar nebula

• doppler shifts

Dark streaming regions seen in light-emitting nebulae formed by areas of dense dust.

• dust lanes

• hydrogen

• emission nebula

• 21 cm lines

The element found in greatest concentration in the interstellar medium.

• hydrogen and helium

• hydrogen

• helium

• calcium

• carbon
