Astrophysics module - question 2. (1 Viewer)

[-X-]

Someone tell me briefly what they did for these:

Perform an investigation to demonstrate the use of filteres for photometric measurements

and...

perform investigation to model light curves for eclipsing binaries using computer simulation

Thanks

That site doesn't do any of the options though so it doesn't have answers to those dotpoints

http://instruct1.cit.cornell.edu/courses/astro101/java/eclipse/eclipse.htm for the second one try that website, it lets you play around with different types of stars

Thanks for that danger. So in the exam, should i just talk about how changing mass/class etc.... affect the graph and stuff?

And for the first dot point, is there anyone who has done it? I dont think many people do astrophysics. :/

Thanks.

Well... i was doing my notes for it and i'll tell you what I wrote but I really think it's on the wrong track and i was hoping someone would come up with something...

The only prac we did that seemed vaguely relevant was to use a ray box and place red and blue filters in front of it to simulate red and blue stars. Then in front of each 'star' we placed red, blue and green filters and measured the intensity of light given out by each. The green and blue filters represented the 'visual' and 'photometric' measurements real astronomers take and then we had readings for three parts of the spectrum of a 'star' and we could getr a rough idea of the shape of its spectrum...and yeah...
does this make sense?

I think this experiment is written up in Jacaranda anyway, or at least the method is
