Three years (and 2 fortnights) ago @plutokiller and I published our first #PlanetNine paper. But science is an iterative process, and since then we've made more progress. The result: an updated P9 Hypothesis (w/ Adams, Becker): arxiv.org/pdf/1902.10103…. Highlights in thread below.
First, an exec summary of the paper: we did thousands of new P9 simulations, and realized that P9 is smaller (m~5Mearth), closer (a~400-500AU), more circular (e~0.2) and visually brighter (V~23) than we originally thought. Pic: @jtuttlekeane Now, let’s dig into the details a bit.
For starters, some history and an acknowledgement: the Planet Nine hypothesis is by no means the first inference of a new solar system member that is based upon anomalous orbital behavior of known objects. But this class of scientific proposals has a long and uneven record.
