NEW PAPER ALERT! "Scaling K2. I. Revised Parameters for 222,088 K2 Stars and a K2 Planet Radius Valley at 1.9 R⊕" https://arxiv.org/abs/2001.11511 (soon in ApJS!) This is the first paper in the "Scaling K2" series, with the ultimate goal of computing planet occurrence rates. But...pic.twitter.com/1AY4I46jce

This means that the Kepler result is not a fluke, and since K2 probes different regions in the Galaxy, this result is not exclusive to the Kepler field! Here's how the radius valley looks in relation to incident stellar flux (left), and compared Kepler (right).pic.twitter.com/zN5ka4wilO

This result would not have been easily identifiable without a uniform set of stellar parameters.pic.twitter.com/nw5qHdkTsB

Not an astronomer, but would it be possible to stratify this result by star system age?If the absence is in younger systems as well, it would suggest they aren't being formed.If they are only absent in older systems, maybe they are being captured by gas giants or smthng like that

Astronomers believe planet formation is complete and solar systems don't change much by ~100 million years after the star forms. Most of these planets are around stars that are billions of years old. There are currently very few planets known around very young stars.
