Happy Dinkinesh flyby, everyone.

In the May release of the exoplanet catalogue, I described some work that had been done sifting through transiting planet candidates from TESS and Kepler-K2 and seeing which of them lined up with Gaia DR3 NSS systems (or nearby eclipsing binary blends). This allowed for the ability to refute each of these candidates. That work has been completed and submitted as a paper submitted to arXiv this month. Our most important result was the discovery that the data that led to the discovery by Livingston (2018) of K2-256 b was actually caused by a nearby eclipsing binary blended with the star. And with that, the Celestia Community now finds itself taking a more active role in shaping this add-on and its contents.

I've become very busy with some things in "real life" and so I've been struggling to maintain this catalogue recently. It's likely to be better in January 2024. There was a paper presenting an updated Kepler planet catalogue (Lissauer, et al.), but I just haven't had time to fully update this addon with its contents. That will have to be deferred to when I have the time. The Kepler planets are in need of a lot of overhauling, and so hopefully that will get accomplished at some point in November. I hope everyone understands. So yes - Kepler-385 has a seventh planet candidate; no - you won't find it here.

05 November 2023
- 138 TESS candidate planets added (TOI-6689 through TOI-6827).

The Kepler planetary systems have undergone an overhaul. The Kepler DR25 data was downloaded from the NASA Exoplanet Archive to serve as a base, and then updated periods and radii were added from Lissauer et al's work, and masses were updated where available from Judkovsky, et al's work. This is quite a large change to the catalogue so it's possible that there may be some unforseen issues but I've done what I can to limit that, including identifying all systems where KOI's were in multi-stellar systems and ensuring that the correct stars were updated with the correct parameters, etc. If anyone finds anything amiss, please let me know.

As a result of some work by Michel & Magrauer, many new stellar companions to planetary systems have been identified. The full list is here:

Thank-you for mentioning this. The problem has been tracked down to a barycenter that didn't have coordinates or an "OrbitBarycenter" line. This issue has been fixed.

I decided to give planetary rotation periods another look. What I've been doing so far is assigning anything with an orbital period < 300 days a tidal equilibrium spin period. This is pretty blunt-force and I've known for a while it could be done better, and I wanted to implement a more tidally-driven model. I'm afraid I can't quite make sense of the tidal spin-down equations I've seen so far, but I've found some formulas on the worldbuildingpasta site that are pretty explicit.

An important consideration here is the system's age. I don't know the ages of many systems, and I've been assuming 5 Gyr for any system without a known age. This was driven by the need to have something other than zero for the internal heating contribution to the temperature/Sudarsky class. Maxine was helpful in guiding me to work by Hurley, et al. (2000) that provides an equation for the main sequence lifetime of a star as a function of its mass. So now I guesstimate the age of a system by taking its most massive star, finding the main sequence lifetime, and halving it. If the main sequence lifetime exceeds the age of the Universe, then I cap the guesstimated age at 7 Gyr.

Tidal dissipation factor estimates tend to be all over the place. I'm using values from Lainey (2016) and Polycarpe (2018) to build a step-function that roughly follows solar system worlds.
If the radius is < 2000, Q=37.5 (Lunar-like),
If the radius is < 5000, Q=99.5 (Mars-like),
If the radius is < 10000, Q=280 (Earth-like),
If the radius is < 35000, Q=500 (Uranus-like),
If the radius is < 65000, Q=1000 (Saturn-like),
If the radius is greater, then Q = 10^6 (Jupiter-like).
Definitely open to revising these numbers, but estimating Q appears to be a very challenging effort for giant planets especially with estimates for Jupiter being discrepant to a couple orders of magnitude.

If the age of the system exceeds the tidal synchronization time for the planet, it is left in the tidal equilibrium spin period. Otherwise, this all allows me to guesstimate spin periods for exoplanets using either the initial spin rate that was calculated as before for giant planets, or for a stand-in initial spin rate (V = 0.5 km/s) for terrestrial bodies (I'm well aware that this is, in reality, effectively stochastic).

The previous version suffered from some issues due to the rewriting of the tidal model for the rotation periods. I've attempted to fix these. I've also completed adding the PHOI (Planet Hunters Object of Interest) designations from Schmitt (2016),. Before, only K2-55 b (PHOI-3 b) had this identifier. I've also adopted impact parameters for some unconfirmed K2 planets from that paper and updated LHS 1678.
