In this lab the student will make use of Wien's Law and the Stellar radius formula to calculate the sizes of a number of stars. Please present your answers in a concise table with star name as on column, and star size in terms of the size of the sun in another column. Relevant Laws: Wien's Law: Amar = 2.98 x 10° /T The value of T is in Kelvin. Stellar Radius Formula: R= R, L, and T must be in terms of the size of the sun. The Sun's temperature is 6000 Kelvin. Calculate the sizes for each of these stars:

**Lab Exercise 2: Stellar Radius Lab** In this lab, the student will make use of Wien’s Law and the Stellar radius formula to calculate the sizes of a number of stars. Please present your answers in a concise table with the star name as one column, and star size in terms of the size of the sun in another column. **Relevant Laws:** - **Wien’s Law:** \(\lambda_{\text{max}} = \frac{2.98 \times 10^6}{T}\) The value of T is in Kelvin. - **Stellar Radius Formula:** \(R = \sqrt{\frac{L}{T^4}}\) R, L, and T must be in terms of the size of the sun. The Sun’s temperature is 6000 Kelvin. Calculate the sizes for each of these stars: | Star name | Luminosity | \(\lambda_{\text{max}}\) | |---------------|------------|---------------------------| | Antares | 550 | 930 nm | | Arcturus | 115 | 690 nm | | Barnard’s star| 0.004 | 1200 nm | | Betelgeuse | 14000 | 930 nm | | Pollux | 42 | 650 nm |
