What are the very bright starts in the upper right of an h-r diagram called?
Hot stars are found in the left hand side of the diagram, cool stars the right, bright stars at the top, and lastly the faint stars are located at the bottom.
Why does the H-R diagram constructed from the data on the brightest stars differ so much from the diagram constructed data on the nearest stars?
The nearest stars - assuming all stars up to a certain distance are actually known - are representative of the general star population. The brightest stars are not. They are... brighter than the average stars.
What is known about stars that are placed toward the top of the H-R diagram?
They are very bright or luminous stars.
Why do stars appear in the night and not in the day?
The faint light of the stars is masked by the bright light of the sun.
What is a gigantism?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
What time stars visible tonight?
As soon as the sun sets and it begins to get dark, stars slowly start to come out. As it gets dark at different times on different days, then the answer is different each day. Bright stars come out first. So sometimes there are bright stars that will appear earlier. It can be interesting trying to spot stars starting to appear. If you know where a bright star should appear, which takes a little knowledge of the night sky or trying over the course over a few nights until you know where to look, you can see them starting to appear. Bright ones appear first and then the dimmer ones.
What is a red gigant?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
Why do the brightest stars in your sky appear so bright compared to other stars in your sky?
because those stars have high luminosities.
Why don't stars appear in photos of astronauts in space?
the light from sun is reflected &it is too bright
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Where are cool red giant stars on the H-R?
Depending on the luminosity they will appear to the right of the HR diagram.
Why are other stars not bright like the sun?
The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.
