Solution
... False. By Wien's Law, since red is a longer wavelength than yellow, the surface temperature of the red one must be smaller. But by Stefan-Boltzmann's Law, its luminosity/area must also be smaller, and they are the same size. So the red one is less luminous. 3. ( T F ) Using parallax, astronomers can ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
