Oh hey, I'm on this site now!

I'll kick off this account by sharing our paper that hit arXiv yesterday.

The title says it all: we found Kepler offers no evidence that Earth-sized habitable zone planets should be more common around M versus FGK stars.

Check it out here: arxiv.org/abs/2310.11613
A comparison plot of recent estimates for the occurrence of Earth-sized habitable zone planets around M dwarfs and FGK stars. The left side of the figure compares results of recent studies for M dwarfs. Our new estimate is more uncertain than these previous works, sharing a 1-sigma upper bound of roughly 40% but now with a lower bound of roughly 1% (instead of previous bounds around 20%), and a median value of 14%. Text at the bottom reads that, for M dwarfs, this occurrence rate is less observationally constrained than previously believed. The right side of the figure includes comparisons to recent studies of Sun-like stars. While there is a range of plotted Sun-like estimates spanning from 5% to 85%, all of these values overlap with the new M dwarf estimate within 1 sigma. Text at the bottom restates that Kepler offers no evidence for higher Earth-sized habitable zone planet occurrence rates around M versus FGK stars.
