FU Tauri b - Imaged (massive) exoplanet

Post by Edasich on 19th September 2011, 9:15 am

http://exoplanet.eu/star.php?st=FU+Tau

But I propose to start a new topic about "Imaged Extrasolar Planets", in order to list them discovery by discovery without starting multiple threads. This could be also worth for all those under-massive brown dwarfs that would eventually be re-classed as planetary companions.
How about?

Imaged ?
I don't see image of the planet (?) in the arXiv paper...

Modified from Luhman et al. (2009) Discovery of a Wide Binary Brown Dwarf Born in Isolation. FU Tauri b is the dim white dot on the left.

Anyway another brown dwarf (or accreting very low-mass star) with a planetary companion.

I thought we look for super earths and earth size planets and not being so far away (800 AU) brown dwarf around another one

More like a brown dwarf binary than a true planet, the mass ratio and separation make formation from a circumprimary disc seem highly unlikely to me. Same goes for the 2M1207 system.

But I propose to start a new topic about "Imaged Extrasolar Planets", in order to list them discovery by discovery without starting multiple threads.

The day is not far when planets will be discovered through direct imaging very frequently. Why would the direct imagery method deserve an independent thread over the radial velocity and transit methods? Of course, very interesting systems like HR 8799 and β Pic would deserve separate threads if this were to happen.

Anyone have any more feedback or ideas regarding this?
