How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
What group does tau ceti belong to in the HR-Diagram?
main sequence
How long is rotation time for the planets?
Each planets has a different length of time it takes to make a full rotation. The approximate lengths are: Mercury: 58 days, Venus: 243 days, Earth: 24 hours, Mars: 24 hours, Jupiter: 10 hours, Saturn: 11 hours, Uranus: 17 hours and Neptune: 16 hours.
Conversion of kg per hr into nm3 per hr?
You cannot convert kilograms per hour (kg/hr) into nanometers cubed per hour (nm3/hr). The kilogram is a measure of mass or weight while the cubic nanometer is a measure of volume. There is no direct conversion, unless you specify the density of the material involved.
How fast is 110 kmph in mph?
110 mph is equal 177.028 km/hr.
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
Why is there no neurton stars in the hr diagram?
Of course they are on the HR diagram. They are simply not on the main sequence.
What types of stars are found on an HR diagram?
All stars.
Where are 90 percent of stars on hr diagram?
main-sequence stars
Why is the hr diagram important to scientist?
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
Most of the stars on the HR Diagram are classified as which type of star?
stars there called stars
Are most of the stars on the HR diagram are classified as which type of star?
stars there called stars
What are the smallest stars in the HR diagram?
The red dwarves.
Where are most stars plotted on an HR diagram?
Main sequence
What are the stars located on the left side of the hr diagram like?
They are very hot stars.
Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The HR diagram does not reference stars on their way to the main sequence, only during or after.
What does the main sequence stars on the hr diagram represent?
Based on initial size and chemical composition a star will enter a band on the HR diagram as a mains sequence star. Stars on the main sequence are in equilibrium from thermal pressure trying to enlarge the star and gravitational pressure trying to collapse the star. Stars on the main sequence range from massive hot blue-white stars to much less massive red stars.
