Why do we square the transit depth?

I don't know what the square root of TD would look likeOh, would it just be what ever the square root of the transit depth is? 757x10^-6??!

An introductory astronomy course which is more like a physics course

What's worrying me is that I don't know algebra... I've hired a tutor but I'm trying to this without him. Thanks for your time and patience

Oh ok. This is where I get lost. How to find Rp

Hmmm but I thought we already have transit depth?

not quite sure what you mean,, but thanks for your patience...would that be 1/2*?

i halved the radius of the sun and that gave me the radius of adam

Homework Statement Astronomers discover a new transiting planet named Jakku. The parent star, Abrams, is known to have a radius equal to ½ that of the Sun’s. a) The transit depth of Jakku is 757 parts per million (757 x 10-6). How large is the planet? Convert your answer into units of Earth...

I can't...but thanks for your time and help. It is much appreciated...

no...i guess back to the drawing board. My head is about to explode...

swap Earth and moon??

r is the radius of the moon, d is the distance, and m is the affected object on the moon??
