Not transiting. The paper claiming discovery of transits was withdrawn by the authors according to arXiv and transits were not detected by MOST.

Yeah, should be Omicron CrB... Could have been cool if another named and a binary star (Alphecca) had a planet. Smile

Who knows? TTV in binaries could be as useful for CVs as for close binaries. Much longer timespans for observations, but...

However amongst notable "absences" I notice these ones missing:

- 4 planets around Gl 676 A
- Planet orbiting "Cronus star" BD+48 740

Plus several KOI candidates for which planetary nature is confirmed and T dwarfs WISE J1711+3500 b and WISE J1217+1626 b with undermassive secondary companions quite in planetary regime.

Was wondering what this one was, turns out I missed it because I was looking for the semimajor axis value, which appears to have been duplicated from the minimum mass.

BD+48 740 is in unconfirmed, as is Gl 676 Ab. The other Gl 676 A planets are indeed missing.

Kepler-36 b and c too. Plus I've received an e-mail announcing that some planets will not be included because either lacking of certain parameters like Kepler-60 and the recently announced ones (I could agree) or not yet published by Kepler website like Kepler-47 (???).

Not published? Shocked

There is an arXiv preprint and a Kepler website page dedicated to Kepler-47 and EPE says, not yet published?

Plus planet count gives now 831 and the catalog 834. I suspect there is still some confusion...

Last I saw, Kepler-47 was in there twice, too (as in, both planets in there twice), at least from the catalogue view.

EPE has a little bit of cleaning up to do.

On top of that, I click on the links to Kepler-47, and get a "Document not found" error. Could that be from the decision not to include them for now?

I have my first lecture to present next saturday. I was going to show this nice histogram with planets discoveries per year. So I have visited EPE today, plotted my histogram.. and suddenly.. this useless **** appears Razz.
http://exoplanet.eu/diagrams/?t=h&f=&x=discovered&xmin=&xmax=&y=raw&ymin=&ymax=
Can anyone help me with that? I really want to present those numbers.

Yeah I'm really not sure where they are getting those numbers, unless there's 200 hidden planets at the EPE. What I did is go to the main catalogue list, sort by year of discovery, select and copy all the rows of a particular year and paste it into programme such as Excel which will give you the number of lines, and take that for the number of planets for that year.

Yes the histogram code does not appear to be choosing sensible buckets for the discovery year...

The EPE histogram tool does not correctly let you set upper and lower limits either...

I also found frustrating that you can't change the units as before (i.e. Earth masses & radii and orbital periods in years).

I am repeating, I know, but the planet count is still lacking planets. I have 855 in total (accounting those ones announced yesterday) whereas EPE signs 849.

GJ 676A I'm aware of (b in unconfirmed, c-e missing entirely ... though probably c deserves to be in the unconfirmed section anyway)

which others?

Recently published WASP planets with not updated parameters. The last MOA planetary system, KELT-3 b, WASP-72 b and two more I don't recall now, perhaps among transiting planets or Doppler ones.

PH-1 is in there under KIC 4862625. Of the microlensing systems OGLE-2012-BLG-0026 seems to be missing was that the one you meant?

The others well spotted, thanks!

HD 4732 b & c, planetary system around K0 subgiant. And this signs 855 (856 + freshly announced WASP-71 b) Wink

It would be even 858 or more than 860 + WISE low-mass T/Y dwarfs, HD 203030 b, GSC 08047-00232, G 196-3 b Rolling Eyes

Oddities
BOKS-1 is mentioned as confirmed in the discovery paper but not categorised as such on the EPE.

Gliese 785 c listed as HD 192310 c in a separate system.

HD 24496 b was mentioned in a paper "FIVE NEW GIANT EXOPLANETS FROM THE CALIFORNIA PLANET SURVEY" that I could only access from a cached copy of the paper mentioned here, but all links to that paper have been replaced by a new paper "The California Planet Survey I. Four New Giant Exoplanets" at the same link in Edasich's post. So I do not know if this planet is retracted. I tried to e-mail Howard (paper's lead author) but got no response. If anyone knows what's up with this planet, please let me know.

KIC 10905746 b and KIC 6185331 b - EPE has them as confirmed planets but their discovery paper explicitly stated they were not confirmed.
We present the rst two planet candidates, discovered by Planet Hunters using Q1 data: KIC 10905746 and KIC 6315331 ... these two candidates are not con rmed planets.
EPE has KIC 12557548 b as a confirmed planet. I do not count it as one.

Several KOI planets are shown to have transit timing variations from which they derive densities, as described in this paper. EPE does not list these planets.

Did not the EPE have Lupus-TR-3 at one time?

Well BOKS-1b, Gliese 676Ab and Lupus-TR-3b are in the unconfirmed section at least. HAT-P-7 "c" is so far as I am aware just a linear RV trend so I'd say its omission is fairly reasonable at this point.

As for the rest, that's quite a lot of missing entries!

I would add HD 203030 b which is planet-mass and a couple of WISE binaries whose secondary masse fall well within planetary domain (8 < m <20 Mj ).

I've tried sending an e-mail to report this, but no results.

Only EPE's bibliography is updated.

I guess this doesnt exist, an 1.12 Rj must be spotted by Keppler. If BOKS-1 b exist it already have a Kepler-XX name.
