Montet and colleagues combined high-spatial resolution and ground-based spectral observations, along with re-analysis of the K2 data, to confirm or refute the planetary status of earlier discoveries. They were able to validate 18 of the original 36 as planets, including a sub-Neptune planet, EPIC 201912552, orbiting a relatively bright M-dwarf star.
As Montet et al. point out, this object is a great candidate for follow-up observations. In fact, it looks like we could see it from Boise State’s Challis Observatory.
Friday’s attendees included Jennifer Briggs, Nathan Grigsby, Catherine Hartman, Tanier Jaramillo, Emily Jensen, and Liz Kandziolka.
