Horizons: Exploring the Universe
Luminosity Spectral Classification Spectra of stars contains clues not only about
their temperature and composition; you can also use a star's spectrum to
determine Whether it is a main—sequence star, a giant, or a supergiant. The
larger a star ...

The Physical Universe: An Introduction to Astronomy
Since the Sun has an effective temperature of 5,800 K, we can estimate that a
10MQ main sequence star would have a surface temperature of about 20,000 K,
whereas a 0.5MQ star would have a surface temperature of only 4,000 K. Thus,
the ...
If stars were being formed and evolving steadily, we should then expect there to
be about 1000 main sequence stars for every pre-main-sequence star of about a
solar mass, so that pre-main-sequence stars would be relatively rare.

Foundations of Astronomy
Once a star consumes all of the hydrogen in its core, it can no longer remain a
stable main-sequence star. More massive stars age rapidly, but less massive
stars use up the hydrogen in their cores more slowly and live longer main-
sequence ...

Astrophysics is Easy!: An Introduction for the Amateur ...
A newly born star is often referred to as a zero-age-main-sequence-star,orzams
for short. There is a subtle but important difference between a zams star and a
main-sequence star. During its long life on the main sequence, a star will
undergo ...

Perspectives on Astronomy, Media Edition
Once a star consumes all of the hydrogen in its core, it can no longer remain a
stable main-sequence star. More massive stars age rapidly, but less massive
stars use up the hydrogen in their cores more slowly and have longer main-
sequence ...

Astronomy: A Physical Perspective
For a main sequence star the mass determines the size and temperature. The
lifetime of a star on the main sequence depends on the available fuel and the
rate at which that fuel is being consumed - the luminosity. Both of these quantities
...
The more mass a main-sequence star has, the hotter its core and the faster it
burns hydrogen, so the hotter, bluer, and brighter the star shines. After its birth, a
star therefore settles onto the main sequence at a luminosity and temperature
that ...

Star Clusters: Saas-Fee Advanced Course 28. Lecture Notes ...
stellar masses among post-main sequence stars, is that the companion to a post-
main sequence star is another post-main sequence star. The addition of the light
from a secondary star is thus not likely to affect significantly the luminosity or ...
