TL;DR: In this article, a least-squares orbital solution using robust estimation yields orbital parameters of period yr, velocity amplitude m s 21, ecP p 6.9 K p 19 centricity, projected companion mass, and semimajor axis.

TL;DR: In this article, a procedure called BLENDER was proposed to model the photometry in terms of a "blend" rather than a planet orbiting a star, where a blend may consist of a background or foreground eclipsing binary (or star-planet pair) whose eclipses are attenuated by the light of the candidate and possibly other stars within the photometric aperture.

TL;DR: In this paper, the authors estimate the mutual Hill separations of planet pairs and find that 93% of the pairs are at least 10 mutual Hill radii apart, and that a spacing of ~20 mutual hill radii is most common.
