TL;DR: The K2-138 system with the most currently known planets was verified in this paper, where the authors verified the sixth planet's orbital period of $41.966 ± 0.006$ days and measure a radius of $3.44+0.32−0.31.
Journal ArticleDOI
Photometry of K2 Campaign 9 bulge data
TL;DR: In this paper, the Causal Pixel Model was extended for less-crowded fields, first by using the pixel response function together with accurate astrometric grids, second by combining signals from a few pixels, and third by simultaneously fitting for an astrophysical model.
