Extrasolar Planets (updated catalogue)

[Sirius_Alpha]

TESS Sector 21 planet candidates are out! Otherwise not a lot from TESS this time. Perhaps it's related to the current global situation.

A huge thank-you to SevenSpheres, LukeCEL, Fafers_br and pedro_jg for identifying problems that have been fixed and new information that has been implemented.

Two papers for TOI-732 were posted to arXiv, presenting different RV follow-up efforts, different orbit solutions and different names. For the orbit solutions I took that of Nowak, et al., purely because it was based off a higher number of data-points.

A number of single-transit planet candidates from TESS and CoRoT had been assigned "default" orbital periods based on the observation baselines of these missions. 50 days for a single-transit planet candidate detected by TESS for example. Instead, orbital periods are now estimated from the duration of the transit (giving the orbital velocity, under the assumption of a circular orbit).

Updated stellar orbits for 83 Leo, GJ 86 and 16 Cyg using Sixth Orbits Catalogue

I remember running into this for the OEC: the implied total mass of 83 Leo AB from the orbit in the Sixth Catalogue is implausibly low, about 0.4 solar masses.

[Sirius_Alpha]

Thanks for that! Do you have a better orbit I can use?

[ajtribick]

Thanks for that! Do you have a better orbit I can use?

Unfortunately I'm not aware of any. Given the length of the orbit I'd guess most solutions would be highly approximate anyway.

I see that the paper which provided the orbit is cited here with a rather different (but also implausible!) value of 5176 days for the period.

The paper itself is paywalled so I can't check what the original values were (e.g. if there was a transcription error into the Sixth Catalogue).

My apologies for the delay. TESS Sector 23 planets are out!

The NASA Exoplanet Archive's unconfirmed Kepler KOI list is a rather interesting place where, as far as I can tell, model-fitting throws bayesian priors to the wind and χ^2 minimization is the rule. "Does a sixteen solar-radius planet with an impact parameter of b=10 fit the data pretty well? That's what we'll go with, then." There were a number of "weird" systems like this that have been fixed by calculating their radius from their transit depth.

Wittenmyer, et al. followed up on 224 Kepler-K2 planet candidates and determined that 30 of them are almost certainly false positives. Because I felt many of them were clearly false positives based on their prior parameters when I was adding them to this catalogue in the past, very few of them were in this addon anyway, and therefore only six new systems have been removed.

[trappistplanets]

how do you install?

[SevenSpheres]

how do you install?

First remove the old exoplanet catalog by editing celestia.cfg to remove the lines "data/extrasolar.stc" and "data/extrasolar.ssc". Then extract the updated catalog to extras.

TESS Sector 24 planets are out! Additionally, new TESS Sector 10 and 11 planet candidates have also been released "after a recent review of the initial vetting for those sectors." Among the more interesting results is that at least two of the super-earths orbiting the nearby, bright star Nu2 Lupi are found to be transiting.

In June, a paper presenting six exomoon candidates was posted to arXiv. It is my opinion that the authors of the paper did not sufficiently make the case for the existence of these moons, having failed to consider the priors associated with the likelihood of additional planets causing the observed TTVs. See comments made after the paper was posted by David Kipping and Alex Teachey, who are leading pioneers in the exomoon field. Due to the problems associated with this research, I have chosen not to add these exomoons to the catalogue.

TESS Sector 25 planets are out!

Many planetary systems discovered by radial velocity feature giant planets in eccentric orbits. With the HST astrometric results for Ups And showing a significantly misaligned system, I have suspected that many of these eccentric multi-planet systems from RV would end up misaligned -- the remnants of a chaotic history of planet-planet scattering. Now we have some results from Gaia astrometry for π Men and HAT-P-11, both of which have an inner transiting planet and an outer eccentric giant planet. Gaia astrometry has detected the 3D orbits of the outer planet in these two systems, and while the 3D orbit of the inner planet is not known, the fact that it transits demonstrates the system is misaligned. π Men and HAT-P-11 are new additions to the (tiny) list of multi-planet systems with constrained mutual inclinations.

A sub-stellar companion was directly imaged around the sub-stellar object DH Tau b. So far, this has been listed as a planet in the exoplanet catalogue, and at eleven Jupiter-masses it has been considered a "planet" so far. Certainly it is less massive than other "planets." Lazzoni, et al. discovered a possible Jupiter-mass companion to DH Tau b. Nature often does not give us neat ways to categorize objects, and it's not clear if DH Tau Bb is a moon around a planet, or a planet around a "star." Their paper does not seem to deal with the issue, but it presents DH Tau Bb in terms of "the first case of a planetary-mass companion around a brown dwarf bound to a star." I have no real interest in arbitrating the nature of DH Tau Bb, so I will simply use the language of the paper and set DH Tau Bb as a planet around a star. Worsening the situation, the authors of the paper state that the DH Tau Bb is unconfirmed because there's a possibility that "DH Tau Bb" may be a PSF subtraction artifact. So, I'm settling on what is probably the least satisfying way to incorporate this paper: Changing DH Tau B to a star and adding DH Tau Bb as an unconfirmed planet. So we stay with one unconfirmed moon and lose a confirmed planet.

A Jupiter-mass companion to a sub-stellar mass companion to DH Tau.

Directly imaged planets. Young star associations are visible, where giant planets are hot enough for easier direct imaging in the infrared.

TESS Sector 26 planets are out!

I've improved the programme I use for this to be able to calculate Mean Anomaly for celestial bodies that have a 3D orbit but whose position on it is given as a position-angle at a certain epoch. This is sometimes done in literature for systems that have very loose orbital constraints. This improvement has allowed me to create more accurate orbits for some stars, as well as finally placing HR 8799's planets in their correct positions, as well as for a number of other directly imaged planets. Huge thanks to ajtribick for helping me with the math for this one.

The southern TESS Continuous Viewing Zone, where the density of TESS-detected planet candidates is higher due to a longer observing baseline.

Nice work!

Need to separate all stars with tag "replace" to avoid conflicts in extras or data, example:

1. When all content of CelestiaExoplanets folder is inside extras folder conflicts with any kind of new "modify" extrasolar ssc file inside extras folder
2. When rename explanets_stars.stc to extrasolar.stc and exoplanets.ssc to extrasolar.ssc to translate and replace in data folder conflicts with stars.dat of AjTribick

Suggestion is to separate addon in the next way:

data/extrasolar.ssc (before called here exoplanets.ssc but in data replace old extrasolar)
data/extrasolar.stc (before called here exoplanets_stars.stc) but without stars with tag "replace"
extras/exoplanet_stars_replace.stc (translate here all stars with tag "replace")
extras/exoplanets_unconfirmed
scripts

Here an easy way without to separate "replace" stars but i dont know if can generate other kind of conflicts is

data/extrasolar.ssc (before called here exoplanets.ssc but in data replace old extrasolar)
extras/exoplanets_stars.stc (original)
extras/exoplanets_unconfirmed
scripts
