Module #2 Measuring and Understanding Stellar Spectra

Lecture A: Total Energy Emitted by Blackboady

UPDATED

Digital Form Checkpoint: Answers these 2 questions in the FORM.


Lecture B: Photon Emission from Atoms

UPDATED
B1: Interactive Exercise: Photon Emission (NEW)

Lecture C: Photon Absorption from Atoms

UPDATED
C1: Ionization and Recombination Emission (NEW)

Digital Form Checkpoint: Open the detector - set the temperature to 30,000 degrees and let the simulation run to 100,000 total events. Enter in the number of ionizing events on the FORM.

Lecture D: Chemical Fingerprints of Stars

UPDATED

D1: Interactive Excercise on Identifying of Stellar Lines

Digital Form Checkpoint: Open the simulatoin Set the temperature to 12000K; selected the element LI for the atmosphere. Enter in the line strength of the 4592 line after the simulation stops on the FORM.

Lecture E: Stellar Spectra and Spectral Classification

UPDATED

Digital Form Checkpoint: Open the simulation - select the star A9--F0V. Measure the line strength (e.g. the equivalent width) of the hydrogen line at 4861 angstroms and enter that value on the FORM
