1. What is the radius of the exoplanet in solar radii?
2. What is the period of the exoplanet's orbit in years?
3. What is the total duration of the exoplanet's transit across the star in years?
1. I used the correct formula for volume this time to get 0.255 solar radii
2. 16.33 years...
If one jupiter mass is 0.001 solar masses
3. There is no transit... :?

I got the same answers for your #1 and #3, but for #2 I got 15.697 years. Did you put the whole system mass?

Heh, I only put in the star's mass . I've messed up enough, you should put up the next question.

1. 2MASSJ22282889-431026
2. variable T6.5 brown dwarf
3. complex clouds or weather patterns that change with altitude and different layers/patches of gas in storms the size of Earth

Who predicted 21 cm HI radiation (and in what year)?
1. What is the name of the center object?
2. When was it discovered, and by who?
3. There is another object in this system that is not visible because it does not emit in visible wavelengths. What is it called, and what (broad category) does it emit in?
4. What star cluster is this object seen in from Earth?
5. What is the name of the object to the right of it, and what kind of object is it?
. I've messed up enough, you should put up the next question.
