wandering anagram stars

By catdynamics on May 15, 2008.

Greg Laughlin at Systemic has put out a teasing hint about a potential major extrasolar planet discovery.

There has been a rumour circling the community that a major extrasolar planet discovery was to be announced imminently.
I do not have any confidential or embargoed information regarding this.

Greg Laughlin in a classical astronomical tradition just posted an anagram allegedly hinting at the discovery - in part to stake turf in case of a scoop, I gather

The anagram is: Huge Applet, Unsearchable Terrestrials!

Go try your luck over at Oklo, report any successes here.

For what is it worth, my solution to the anagram is:

TrES alleges Alph Centauri B Super Earth!

TrES is a major, active transit survey

This is a guess. Had to stretch a bit to accommodate the missing "a".
It will be huge if true.
I am looking forward to hearing all about it, real soon now.
Bonus if it is in the habitable zone.

PS: Ok, now I like Alpha Centauri B Super Earth, Resist Glee! better.

Previous limits on Alpha Cen B companions were about 0.5 Jupiter masses inside 0.2 AU going to about 2 Jupiter masses out at 2 AU
so plenty of room for a super earth inside an AU.

Or, as Brian notes below, the Alpha Cen may be a red herring and this is a teaser for a completely different result.
The CTIO observations of Alpha Cen commence may 19th, the Europeans did look at it, don't know if anyone else down south took a preliminary look at Alpha Cen.

PPS: Greg has stated the solution does not include the words "super" or "earth" and does include a "German name".
Now, "Herschel" springs to mind, looking at the letters on offer, but a better choice might be "Euler" combined with the word "phase" maybe?
Oh, and "Gliese" also, goes without saying...

The non-denial of "Alpha Centauri" or variants thereof is also intriguing but possibly a red herring. Lack of an "O", "K" or "V" limits the options sharply - eg it can't be about Struve's star.

Howsabout: Alpha Cen B Terrestrials Tug Euler Phase?!

Note to those who don't regularly read Systemic: to read the comments associated with a post on the Systemic blog, you have to click on the number after the post's title. From conversation in the real world, I've gathered that this seems to be completely obvious to some readers and not obvious at all (ever!) to others.

"Greg Laughlin in a classical astronomical tradition just TrES is a major, active transit survey"

Can someone translate this into English for me? I understand it is huge if true.

Two problems with the TrES hypothesis: two of the telescopes are in North America and can't reach -61d declination, and I'm pretty sure that alpha Cen B would saturate even a 10cm aperture. Alpha Centauri seems like a reasonable bet for the overall topic, though.

For any bloggers who want to start prepping the nerd culture references, I recommend that you start here.

It doesn't have to involve Alpha Centauri B, though:

"Herschel bags terrestrial planet" is in there, with what looks like enough vowels left over to make an abbreviation for a star name. Something involving the Utrecht Echelle Spectrograph?

Hm, not enough consonants left.

I can get: Large Hints Euler Phase Perturbs Eta Lac

or Euler Phase Perturbs Eta Lac, Earthlings!

In fact "eta Lac" comes up a lot as a "non-word" residual. Nice star, or it would be if it were a proper star - Lac is so feeble that only alpha and beta Lac are formally designated, though there must be an eighth brightest star in there.
However HAT P-1 transiting star is in Lacerta... it is the most inflated of the known hot Jupiters, which could be a sign it is being perturbed and tidally pumped, since its period is a respectable 4.5 days.

just a short comment: it seems that there is a sentence in Greg's text which has been overlooked, and might in fact give a clue: "After all, there are only so many nearby *red dwarfs* in the sky"...This would probably rule out Alpha Centauri.

or am I missing something?

I saw that, which is why I was contemplating Struve's stars.
But there is no "M" or "D" etc in the anagram.
There is a Gliese - so could be interesting new low mass M star planet, but Greg is being too clever with his phrasing.

Though I did notice we managed to take down his server, briefly.

Gliese charts a bluer, superearth planet!

What do I win?

Steinn asks "Which Gliese?"

One possibility appears to be "Gliese 310Aa".

You can spell out some numbers along with the word Gliese - for example, Gliese three ten, and then you are left with:
(gliese three ten Aa)(upplet,Usrchabl star !)

If I understand this table correctly: http://www.ari.uni-heidelberg.de/datenbanken/aricns/gliese.htm, "Gliese 310Aa" is a valid star designation.

Other possibilities for spelling out the numbers so that other star catalog designations can be used include "three", "ten", "eight", and "thirteen"...

Hm. Gliese 3 is a bright K5V star, but it is far south.

Eight and thirteen suffer from lack of "I"s.

Gliese 10 is 6 Cet - an F5V star, little bit south, not likely.

I thought eight and thirteen, which are in the original anagram, might be helpful if solution involves a designation from another (non-Gliese) catalog.

While we are talking about partial (non)solutions, I'll just mention that Tau Ceti is also in the original anagram, as is "Herschel bags tau ceti planet euler" (+rrpsar), and for the partial solution "Herschel bags terrestrial planet", the leftovers - PSAUUE - include the sourthern constellation "Apus", and its official abbreviation "Aps", as well as PsA (short for Piscis Austrinus). But I can't figure out what to do with the rest.

I think one good search strategy might be to check what known exoplanet system star designations show up in the original anagram -- Greg's work seems likely to involve adding an additional planet to a known system.

Yup.
I doubt Herschel, unless Greg is using poetic license to refer to late 18th century descriptive observations of Herschel himself - while there are Herschel telescopes etc, none that I know of do serious planet hunting.
Euler would be a theoretical result on existing data set, Gliese would of course refer to the catalog.

Tricky.

Following Gliese catalog stars have known planets: 86, 317, 581, 674, 849, 876

Following primary name planet hosts fit in the anagram, at a quick glance:
AB Pic
HAT-P-three
Lupus Tr three
Ups And
eps Tau
ChaHa eight
- all of these suck as candidates for interesting new stuff, for various reasons.

And you can add "TRES-Three" to the list.

Maybe we shouldn't count out Herschel yet -- the Herschel telescope in the Canary Islands seems to be used for planet hunting and even for planetary light gathering (reference: http://physicsworld.com/cws/article/print/731). It is even part of TRES - it contributed to finding TRES-1 (reference: www.hao.ucar.edu/public/research/stare/tres1.pdf). Sadly, TRES-Three and Herschel can't both be in the anagram.

yes, tres three would work - ups and of course doesn't - it is supposed to be stricken from the comment list

Eps Eri also works - and is a well studied and interesting system
Can't fit a german name in with Eps Eri and get a sensible residue though

actually I am now intrigued with Eps Eri - there are interesting possible residuals in the orbit, and the planet should have gone trough periastron about a year ago - expect there was Spitzer data to see if the disk brightened, and the radial velocity campaing should have increased tempo and fidelity

an inner, lower mass planet around Eps Eri would be very interesting.
I also note with interest that Subaru can be contained within the anagram, as of course can HET...
