HSAUR3 (version 1.0-15)

CYGOB1: CYG OB1 Star Cluster Data

Description

Energy output and surface termperature for Star Cluster CYG OB1.

Usage

data("CYGOB1")

Arguments

Format

A data frame with 47 observations on the following 2 variables.

logst

log survface termperature of the star.

logli

log 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.

Examples

Run this code

  data("CYGOB1", package = "HSAUR3")
  plot(logst ~ logli, data = CYGOB1)
