A planet around BDS 10966A?

Post by Lazarus on 6th March 2009, 3:38 pm

Toyota et al. (2009) "Radial Velocity Search for Extrasolar Planets in Visual Binary Systems" (pdf)

There may be a m sin i = 8.1 Jupiter masses planet orbiting the K giant star BDS 10966A (a.k.a. HD 203857), but there are other possibilities, e.g. nonradial pulsation, rotational modulation. Note that BDS 10966 is probably not a physical binary.

The paper also lists some other stars which may have unseen companions.

Ok, I was browsing EVII forum a bit unimpressed, expecting to see some replies in Kepler launch's topic, but then....

I see "planet" in Extrasolar News and Discoveries Section". I click and then I see a brand-new planet around a giant star.
Well, I think my face's expression turned out like this:



I meant to give some dramatic power to this thread lol!

Seriously. It's another good result from Okayama Planet Search.
Plus here I see evidences of brown dwarf companion within habitable zone around Psi1 Draconis A (and lots of radial velocity sets...*yum*) and another one either a superplanet within extended water zone of orange giant-subgiant 27 Hydrae A. alien affraid

I'm expecting even more planets around giants.

More, more.

Where do you see a circumbinary planet? HD 203857 seems to be a single star.

Thanks for the paper, Lazarus, pretty interesting!

Wrong draft. Actually I was meaning "in a possible [optical] binary with giant component", but it seems like it's neither that one, but a single star.

Fixed. cyclops
