| Detection of carbon monoxide in the high-resolution day-side spectrum of the exoplanet HD 189733b http://arxiv.org/abs/1304.4014Including a measurement of the planet's orbital velocity (effectively an eclipsing double-lined spectroscopic binary), allowing to solve for the mass of the star. Not sure if this has been done before for HD 189733 — IIRC only for HD 209458 and Tau Boötis. | |

| And a tentative detection in 51 Peg b.
It' s the same team and instrument (CRIRES VLT) than in previous papers. | |
