Question

lc2 hr diagram drill: name any constellations you know? choose one star to research and complete the following information using a search engine on your laptop. constellation: star name: luminosity (how bright is it): temperature: color: what is its star classification: draw an x where your star would be on this chart. complete these sentences using the chart: as the temperature decreases a stars color goes from white to to to. red stars are the stars. as the size of a star increases its luminosity. use your diagram to complete white/blue = hotter orange/red = cooler

Explanation:

For the constellation - naming part, common constellations include Orion, Ursa Major etc. For the star - research part, information can be found via search engines. Analyzing the HR diagram, as temperature decreases, color changes follow a pattern and red stars have a certain temperature - related characteristic, and there is a relationship between star size and luminosity.
For example, if we choose Sirius in the Canis Major constellation:

• Constellation: Canis Major
• Star Name: Sirius
• Luminosity: about 25.4 times that of the Sun
• Temperature: about 9940 K
• Color: White - blue
• Star Classification: A1V

On the HR diagram, Sirius would be in the main - sequence region near the upper left (hot and bright).
As the temperature decreases a star's color goes from white to blue to yellow to orange to red. Red stars are the coolest stars. As the size of a star increases its luminosity increases.

Answer:

Constellation: Canis Major
Star Name: Sirius
Luminosity: about 25.4 times that of the Sun
Temperature: about 9940 K
Color: White - blue
Star Classification: A1V
As the temperature decreases a star's color goes from white to blue to yellow to orange to red. Red stars are the coolest stars. As the size of a star increases its luminosity increases.
