To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.

What type of star is the hottest on the H R diagram?

The hottest type of star on the Hertzsprung-Russell (H-R) diagram is typically a blue star, which falls in the top left portion of the diagram. These stars are usually massive and have high surface temperatures, leading to their blue coloration and positioning on the diagram.


What is a star diagram in celestial navigation?

A star diagram in celestial navigation is a graphical representation of the positions of specific navigational stars in the night sky at a particular time and location. Navigators use star diagrams to determine their position at sea by measuring the angles between the stars and the horizon and comparing them to precalculated values. This technique helps mariners to establish their latitude accurately.


What does an H-R diagram relate a star's temperature to?

The temperature is displayed along the horizontal axis while the vertical axis is the star's absolute magnitude. So the HR diagram is a scatter diagram relating temperature and brightness, and eah star occupies one point.


What is the main sequence phase of a star?

The main sequence phase means that, if you plot an H-R (Hertzsprung-Russel) diagram, it is in the so-called "main sequence", the area in the graph where you find the majority of stars. Those are the stars that currently fuse hydrogen into helium.


When a star changes its position in the HR diagram it is because the star is?

undergoing changes in its temperature and/or luminosity, which affect its spectral type and position on the HR diagram.

What two caracteristics of a star are plotted on the Hertzsprung-Russell diagram?

The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.

What info does a H R diagram give us?

H-R diagrams are used to plot brightness against size and spectrum of a star. For eg, The sun is a medium sized star or a G type star with luminosity showed by surface temperature of 5, 500 degrees centigrade.
