Question

Please include all intermediate steps. That the stars emit radiation as a black body, find the total emissive power (E [W/m^2]) emitted by Star A (EsA [W/m^2]) and Star B (EsB [W/m^2]), respectively? The wavelengths associated with UV, Visible, and IR parts of the spectrum are defined in Table 1. Wavelength limits: UV (0.0-0.4 μm), VIS (0.4-0.7 μm), and IR (0.7-100 μm). Calculate the fraction of solar emission for Star A and Star B that lies in the UV, Visible, and IR regions. Assuming the planets are the same size and distance from Earth, which star will be the brightest to an observer on Earth? Explain your reasoning.

You observe two stars in the night sky. Star A has a surface temperature of 10,000 K. Star B has a surface temperature of 2,500 K. a. What is the peak wavelength of the blackbody radiation emitted by each star? (2 points) b. In what portion of the electromagnetic spectrum (e.g. X-ray, Visible, Radio, etc.) does each star's peak wavelength of blackbody radiation fall? What color do you think they'd appear to human eyes? Explain. (2 points) c. Star B has a radius four times that of Star A. You can assume the stars are spherical in shape. What is the ratio of the intrinsic energy per unit time emitted by Star A to that of Star B. (2 points)

We measure the black body spectrum of a star in a star cluster and find that it has a surface temperature of 10,000 K. Assuming the star is a Main Sequence star, what is the luminosity in Watts? The sun's luminosity is 3.91 x 10^26 Watts. If the measured intensity of the star is 8.1 x 10^-1 Watts per square meter (W/m^2), how far away is the star in light years?

(Part A) Consider a blackbody that radiates with an intensity I2 at a room temperature of 300K. At what intensity will this blackbody radiate when it is at a temperature of 400K? (Part B) At what wavelength (lambda m) would the intensity of blackbody radiation be at a maximum when the blackbody is at 2900K? (Part C) An astronomer is trying to estimate the surface temperature of a star with a radius of 5.0x10^8 by modeling it as an ideal blackbody. The astronomer has measured the intensity of radiation due to the star at a distance of 2.5x10^13 and found it to be equal to 0.055 W/m^2. Given this information, what is the temperature of the surface of the star? Express the answer in K.

00:01 All right, so let's say we have star a that has a temperature of 10 ,000 kelvin, and then we have star b, which has a temperature of 2 ,500 kelvin.
00:15 So part a asks, what's the peak wavelength for each of these? so the peak wavelength for star a is going to be rewrite it in presumably nanometers.
00:24 We write this as 2 .9 times 10 to the 6 nanometers times a kelvin, divided by the temperature.
00:30 Which is 10 to the 4th kelvin so our kelvin units cancel out and we'll just get 290 nanometers and then star b it has one -fourth of the temperature of star a so we could really write this as like four times the wavelength of star a to maybe make things a little bit easier so that is 1160 nanometers i believe and so that's part a, part b, want to know what portion of the electromagnetic spectrum is each of these.
01:10 So star a, this is like ultraviolet, and then star b, this is infrared.
01:16 Part c, what color would they appear to the human eyes? so this would appear like blue, and this would appear red, sorry, and then part c...
