6.1: Identifying Absorption Lines in Blue Sky and Solar Spectra

Identifying Absorption Lines in Blue Sky and Solar Spectra Spectroscopic analysis is one of the cornerstones of astronomical research. By observing how the spectra of different astronomical objects behave, we can make grand conclusions about the nature of our universe. The solar spectrum is full of minute details which hint to the underlying physical processes […]

6.2: The Distance and Age of an Open Cluster

The Distance and Age of an Open Cluster Star clusters can serve as important tools to study the star formation, the dynamics of the ISM, and the evolution of our galaxy. They provide Astronomers the opportunity to study stellar populations where members might share many observational properties. These properties may include astrometry (space velocities, group […]
