CYG OB1 Star Cluster Data
Description
Energy output and surface termperature for Star Cluster CYG OB1.
Usage
data("CYGOB1")
Format
A data frame with 47 observations on the following 2 variables.
logstlog survface termperature of the star.
loglilog light intensity of the star.
Details
The Hertzsprung-Russell (H-R) diagram forms the basis of
the theory of stellar evolution. The diagram is essentially a
plot of the energy output of stars plotted against their surface
temperature. Data from the H-R diagram of Star Cluster CYG OB1,
calibrated according to VanismaGreve1972 are given here.
