An Independent Planet Search In The Kepler Dataset. II. An extremely low-density super-Earth mass planet around Kepler-87
Ofir, et al.

Kepler-87 is found to have two planets in a 5:3 mean motion resonance. The inner planet is a Jupiter-like object, while the outer planet is an extremely low-density super-Earth. Their densities are unusually low for their age and temperature.

Just read about PSO J318.5-22... Strange indeed! :o

MOA-2011-BLG-293Lb: First Microlensing Planet possibly in the Habitable Zone
Batista, et al.

The light curves in microlensing events often do not reveal much information about the host star, leaving the properties of the system poorly defined. Last year Yee et al reported a giant planet orbiting an M dwarf. New Keck observations reported here show that the host star is actually a G dwarf. This makes a significant revision to the system parameters.

Stellar Spin-Orbit Misalignment in a Multiplanet System
Huber, et al.

Kepler-56 is a red giant with two transiting planets. The stellar rotation axis is inclined to the plane of the sky, making it misaligned with the two known planets. RV data suggests a third companion in the system further out, and is likely responsible for tilting the system. Kepler-56 becomes the first star known to be misaligned with a coplanar planetary system (at least the two transiting planets).

Direct Imaging and Spectroscopy of a Candidate Companion Below/Near the Deuterium-Burning Limit In The Young Binary Star System, ROXs 42B
Currie, et al.

A substellar companion has been imaged orbiting a young binary M dwarf in the Rho Oph star-forming region. It's spectrum is comparable to young, low surface gravity objects with masses straddling, or below, the deuterium burning limit. A second candidate companion is also imaged but not confirmed.

Not sure how relevant it is to Celestia.Sci, but the mass of Kepler-78b has been determined. It's density is consistent with an Earth-like composition.

This work was a lot in the German media, not the least because Cabrera and collaborators work in Germany. Independently, I think the finding is quite stunning. Since the 7 planets orbit at much smaller distances from their star than our first 7 planets from the Sun, one might have to consider some nifty scaling relations to map that new system onto our solar system? ;-) Interesting stuff in any case...

In the context of studying possible twin systems of our solar system, the composition of the planets seems most interesting. Hence size AND mass determinations seems what we need.

Revisiting the proposed circumbinary multi-planet system NSVS14256825
Hinse, et al.

Last year, Almeida et al proposed a two-planet system to explain the eclipse timing behaviour of the eclipsing binary system NSVS 14256825. The orbital parameters of the two planets were crossing, and I'm not really sure why they didn't consider the system stability in their study. Wittenmyer et al found the system to be unstable. Now, a reanalysis of the eclipse timing measurements suggests that there is no second planet, and the first planet may be quite different than originally suspected.
