Re: discovery of a new Exoplanet

[Aage Sandqvist <aage.sandqvist@astro.su.se>]

Hi Morten:

I don't have access to NY Times, but one can read about the discovery on 
the "Länk till Extrasolar Planets Encyclopaedia" - Latest News: 31 
March,  Direct Detection by imaging of a young few Mj companion to GQ 
Lup - preprint, or ESO Press Release


Spectral lines in the companion are seen emanating from Water (H2O), 
Neutral Sodium (Na I), and Carbon Monoxide (CO). Comparison with models 
cannot tell anything about the "surface". If it is a planet, which is 
not 100% certain, it is still a giant GAS planet.

Cheers,

Aage.
