Can Planets Maintain Vega’s Debris Disks?

Vega’s system of debris disks can be explained by a series of planets that constantly transport material inwards towards the star.

Kepler 2.0

The Kepler Space Telescope gets a promising second chance with a new mission called “K2″.

Can Scattering Explain Eccentric Planets?

New dynamical simulations show that close-in planets on eccentric orbits can arise from planet-planet scattering — but only if the scattering occurs on larger orbits and is followed by inward migration.

Fomalhaut’s Little Sibling Has a Debris Disk Too

A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.

IceCube Detects Extraterrestrial Neutrinos

The IceCube project at the South Pole makes the first detection of high-energy extraterrestrial neutrinos.

Debris Disks and Stars Spin Together

Herschel observations reveal that debris disks are aligned with their stars’ equators, unlike some close-in transiting exoplanets.

How Did Tatooine Form?

Dust traps may be the key to forming Kepler-16b and other circumbinary planets.

What’s Next For Kepler?

NASA is looking for a new mission for the damaged Kepler space telescope. Here are some ideas.

A Core Matter

The mass of the cores of giant planets affects their luminosity after formation, complicating how we determine the mass of directly imaged planets.

Recap of the IAU Planet Formation Symposium
