TL;DR: The most sensitive direct imaging and radial velocity (RV) exploration of epsilon Eridani to date is presented in this paper, where a new compilation and analysis of precise RV data spanning 30 years is presented, and combine it with upper limits from direct imaging search, the most sensitive ever performed.

TL;DR: The most sensitive direct imaging and radial velocity (RV) exploration of Eridani to date is presented in this article, where the RV data and direct imaging upper limit maps were combined in an innovative joint Bayesian analysis, providing new constraints on the mass and orbital parameters of the elusive planet.

TL;DR: In this paper, the authors measured the scattering phase functions in the 30 •-150 • scattering angle range and found the halo dust is both more forward-and backward-scattering than the ring dust.
