Get the money

February 28th, 2012

It’s likely that everyone who reads this site has already seen the new Kepler candidates paper. Drawing on 16 months of photometric data, and importantly, on significant improvements to the reduction pipeline, it gives details on 2,323 planet candidates. The cumulative planet candidate table, in particular, makes for interesting reading.

In true Gordon Gekko style, I ran the new candidates table through my valuation formula (see here, here, and here.)

A screenshot of the results, for candidates with valuations greater than ten dollars are shown below. KOI 2650.01 and KOI 2124.01, assuming that they hold up, are both million dollar worlds. The total value of the current catalog is 10.9M.

    It is highly encouraging to see you posting again. Welcome back :). Keep up the great work.

    I think both of those candidates demonstrate the problems with the effective temperature part of the valuation formula. Comparing incident flux, 2650.01 is receiving 87% greater flux than the Earth, while 2124.01 receives 91% greater flux, which turns out to be the same value as Venus.

    Investigating the tables reveals you’ve got the valuation formula calibrated to give optimum values at roughly 30% greater insolation than Earth.

    Hi Greg,
    If I could add some comments as well – it is really, really, great to have you back (as well as everyone else). Another related area is how the HZ is defined, which seems to continually evolve. It is summarised in section 7.3. of the paper (without repeating everything here).
    Cheers.
