| Abstract: |
Balmer series line strength is known to depend on photospheric stellar temper- ature. In the past astronomers relied on the H¯ line to determine the temperature of spectral type B, A, and F stars. The development of detectors that are more sensitive to red wavelengths now makes it easier to observe the H® line. This thesis presents a list of the H® values for several standard stars scattered throughout the sky and easily viewed from the northern hemisphere. Stars from the Pleiades, Hyades, Coma, and NGC 752 star clusters are included as well. This color index may be used to determine stellar temperature for spectral type B, A, F, G, and K stars. The obser- vation method is independent of instrumentation. Data were obtained at the West Mountain Observatory of Brigham Young University. |
