Question

How can you figure out the properties of a star?

Answer 1

Answer:

Analyze the Characteristics of a Star

Explanation:

Surface Temperature

First, you want to determine the color of the star - this can determine the heat and age of the star.

Second, you want to measure the spectrum and get the spectral type.

Chemical Composition

Determine which lines are present in the spectrum.

Luminosity

Measure the apparent brightness and compensate for distance

Radical Velocity

Measure the Doppler shift in the spectrum.

Rotation

Measure the width of spectral lines.

Mass

Measure the period and radial velocity curves of spectroscopic binary stars.

Diameter

1. Measure the way a star’s light is blocked by the Moon.

2. Measure the light curves and Doppler shifts for eclipsing binary stars.

Answer 2

Answer:

Measuring distances to stars through stellar parallax. Measuring distances to stars through the moving cluster method. Astronomers measure the temperature of a star by looking at the star's color and its spectrum. The apparent brightness of a star tells how bright it seems to us
