    I have a new paper out today! "Scaling K2. II. Assembly of a Fully Automated C5 Planet Candidate Catalog Using EDI-Vetter" The first fully automated analysis of transiting K2 exoplanets.

    Special thanks to all the collaborates on this project: , , , Ian Crossfield, Erik Petigura, , and David Ciardi. Look out for more to come in the near future from the "Scaling K2" series!

    Put it all together and you've got the ingredients for an exoplanet occurrence rate. Watch out for an upcoming paper on the our first analysis of this K2 C5 data!

    4. A measure of the false positives (the number of signals that look like planets but are not) in your sample. We flip the light curves (removing all true planet signals) and run our detection pipeline looking for signals that look like planets.

    3. A measure of the false negatives (the number of un-detected planets) in your sample. We inject false signals into the data and see how many we recover.

    2. A uniformly detected planet sample. Our paper introduces EDI-Vetter. A fully automated vetting machine able to parse through the data and find the true planet signals. We found 75 candidates, including 8 new planets!

    You need 4 ingredients to calculate an exoplanet occurrence rate: 1. A uniform stellar sample. just released a paper creating such a sample. "Scaling K2. I. Revised Parameters for 222,088 K2 Stars and a K2 Planet Radius Valley at 1.9 R⊕"

    For clarity, the first fully automated analysis!

    You need 4 main ingredients to perform an exoplanet occurrence rate: 1. A uniform stellar sample. just put out a paper creating such a sample. "Scaling K2. I. Revised Parameters for 222,088 K2 Stars and a K2 Planet Radius Valley at 1.9 R⊕"

    NEW PAPER ALERT! "Scaling K2. I. Revised Parameters for 222,088 K2 Stars and a K2 Planet Radius Valley at 1.9 R⊕" (soon in ApJS!) This is the first paper in the "Scaling K2" series, with the ultimate goal of computing planet occurrence rates. But...

    Today we bid adieu to another space telescope that helped kick start my research. joins Kepler in retirement, drifting along in their Earth-trailing orbits. Farewell my infrariend, thanks for all the brown dwarf and exoplanet follow-up!

    "The project is now managing to a March 2021 launch date but estimates only a 12 percent likelihood that this date will be achieved." With each additional overrun and delay, it gets harder to defend JWST—and also, perhaps, the hallowed Decadal Survey process that created it.
