Well-known exoplanet researcher Dr Michel Mayor ( discoverer of Peg 51b with Dr Didier Queloz in 1995 ) today announced the discovery of the lightest exoplanet found so far. The planet, “e”, in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist:

And did you notice this was published in the "Journal of Astrobrewology"?

After that April Fools joke… here's an actual result about a Super Earth atmosphere. This is an exciting result, not only for the case of this one planet, and the general case of Super Earth atmospheres, but for the development of the technique:
http://www.blastr.com/2017-4-11/astronomer...t-whats-it-made I'd point out that the minimal radius seen in any of the filters is not necessarily the surface – it could be the level of cloud tops, in which case, we're learning about the composition of the atmosphere above the cloud tops. I think a successful application of this technique is a nudge in the direction of favoring red dwarf systems over sunlike star systems in the contest for funding / further research. Of course, both merit interest, but this technique is unlikely to work for many planets in the habitable zone of nearby sunlike stars. |
