Based On Its Location On The Hr Diagram What Can We Say About Rigels Mass And Lifetime

The layers collapse on the core. Its mass is about 5 m sun and its lifetime is about 10 9 years.

Properties Of Stars

So this is the main point to keep in mind.

Based on its location on the hr diagram what can we say about rigels mass and lifetime. The hr diagram spans a rather large range in luminosity from 10 4 l on the low end to as much as 10 6 l on the high end. The diagram was created circa 1910 by ejnar hertzsprung and henry norris russell and represents a major step towards an understanding of stellar evolution. This interactive applet might help you visualize some of the properties of the hr diagram.

Higher mass stars will have surface temperatures and luminosities that place at the upper left end of the main sequence and lower mass stars will have parameters that place them at the lower right. Transcript of rigels life cycle by seth husney. A stars luminosity is the.

The hertzsprungrussell diagram abbreviated as hr diagram hr diagram or hrd is a scatter plot of stars showing the relationship between the stars absolute magnitudes or luminosities versus their stellar classifications or effective temperatures. Nothing because it is not on the main sequence. Less luminous cooler smaller and less massive compared to a main sequence star with a short lifetime a main sequence star with a long lifetime is.

The main sequence is a mass sequence. Based on its location on the hr diagram what can we say about rigels mass and lifetime. The related color.

The main sequence stretching from the upper left hot luminous stars to the bottom right cool faint stars dominates the hr diagram. Based on its location on the hr diagram what can we say about rigels mass and lifetime. As time goes on hydrogen fusion in the core of a star becomes inefficient and can no longer hold the other layers of the star.

Classifying stars the hertzsprung russell diagram there are a few hundred billion stars in our galaxy the milky way and billions of galaxies in the universe. Of the 12 brightest stars in our sky most are giants and supergiants. More simply it plots a stars luminosity against its temperature.

Its mass is about 5 m sun but we cannot determine its lifetime. Its lifetime is about 10 9 years but we cannot determine its mass. There are 3 main regions or evolutionary stages of the hr diagram.

Answers antibiotics free full text the diagram below shows a bacterial replication fork and its principal proteins. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns. As this happens the temperature rises in the star until it is hot enough to fuse helium into carbon.

It is here that stars spend about 90 of their lives burning hydrogen into helium in their cores. Answers the diagram below shows a bacterial replication fork and its principal proteins. Patterns in the h r diagram.
