Question

1. what is the relationship between the color, temperature, and luminosity of a star? (finish the sentences correctly)

if the color is blue then...
if the color is red then...

1. what is the relationship between the size, temperature, and luminosity of a star? (finish the sentences correctly)

the bigger the star the...
the smaller the star the...

1. what do the x and y axes represent? include a direction in your answer. for example, “the x - axis is time and as you move right, the time increases.”

part ii: click on “planetarium simulation link” (you will then have to click on the square/arrow on the top right corner of your screen to get to the site and then click on adobe flash player and then click “allow”). next, scroll through the night sky and hover your mouse over any 3 stars. finally, fill out the table...you will need to use google after you find the names of the 3 stars you picked.
hr diagram - you may need to use this link to help you answer these questions.
name of the star magnitude spectral class color life - cycle stage

Explanation:

1. Blue - colored stars are hot and have high luminosity. Red - colored stars are cooler and have lower luminosity.
2. The bigger the star, the higher its temperature and luminosity. The smaller the star, the lower its temperature and luminosity.
3. Without seeing the specific diagram, in an HR - diagram (which is likely relevant here), the x - axis usually represents spectral type or temperature (from hot on the left to cool on the right) and the y - axis represents luminosity (from low at the bottom to high at the top).

Answer:

1. If the color is blue then the star is hot and has high luminosity. If the color is red then the star is cooler and has lower luminosity.
2. The bigger the star the higher the temperature and luminosity. The smaller the star the lower the temperature and luminosity.
3. In an HR - diagram, the x - axis represents spectral type or temperature (hot on left, cool on right) and the y - axis represents luminosity (low at bottom, high at top).
