Radius/period probability distribution #21

Open ericagol opened 8 years ago

ericagol commented 8 years ago

Perhaps the radius/period probability distributions could be plotted in Figure 5 with the full probability distribution function (such as in the upper left panel of Figure 3).

We did this for Kepler-36b/c with radius vs. mass in this figure:

Also, it would be interesting to look at the joint impact parameter distributions & eccentricity distributions of the candidates. I would expect the former to be roughly uniform (with a slight fall-off at high eccentricity), and the eccentricity distribution i would expect to follow the prior, with perhaps a slight preference for large eccentricity due to the higher transit probability of eccentric planets at periastron.

I've attached the plot that your'e asking for in your comment. I don't really want to include this in the paper because it's a bit too messy but it is interesting to see!

Note: I've also changed this plot to only include the short period planets in our target sample... I think that's probably the better comparison.

Nice plot!

ericagol commented 8 years ago

Perhaps you can an an indicator in Figure 5 showing the minimum period that each planet can have given that there is not another transit observed in the Kepler dataset?

Good idea. Attached: full_sample_plus_cands-1

Nice! Now I'm thinking I'm seeing the gap again... definitely worth following up on.
