Composition and Temperature of stars.

For this project, our team is Benoit and Jimmy, and our goal is to find the composition and temperature of stars. Our question is: The diferent compositions and temperatures between the sun and Vega. We found an experiment to discover the temperature of the sun with the law of Wien and that was a success because the sun temperature's surface (photoshere), is 6000 K (Kelvin or Degrees is the same because the temperature is too hot to see a difference, Kelvin= 273+°C), and we found 6100 K. We found an other experiment for composition but for the moment it was a failure and not finished. The material necessary is a white light, arc condenser, a lens, a slit, salt in ethanol solution (to burn), a prism and screen.
 Here we have a video of the composition of stars. And with the last experiment, which recreates how we made the Newton telescope.

In the second part, we had a school outing with Mr Moulat to use a telescope and to find an other star and compare it with the composition and temperature of the sun. For this we used a Newton telescope.

 Now all we can do is wait.
