Revealing Giant Planet Interiors Beneath the Cloudy Veil

Tristan Guillot, Leigh Fletcher

Observations from the Juno and Cassini missions provide essential constraints on the internal structures and compositions of Jupiter and Saturn, resulting in profound revisions of…

The search for radio emission from the exoplanetary systems 55 Cancri, Andromedae, and Boötis using LOFAR beam-formed observations

Jake D. Turner, Philippe Zarka, Jean-Mathias Grießmeier +8

Observing planetary auroral radio emission is the most promising method to detect exoplanetary magnetic fields, the knowledge of which will provide valuable insights into the plane…

Hiding Signatures of Gravitational Instability in Protoplanetary Discs with Planets

Sahl Rowther, Farzana Meru, Grant M. Kennedy +2

We carry out three dimensional SPH simulations to show that a migrating giant planet strongly suppresses the spiral structure in self-gravitating discs. We present mock ALMA contin…

Spitzer's Solar System studies of asteroids, planets and the zodiacal cloud

David Trilling, Carey Lisse, Dale P. Cruikshank +13

In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground-breaking infrared measurements of Solar System objects. In this second of two p…

On the diversity of asymmetries in gapped protoplanetary disks

Nienke van der Marel, Til Birnstiel, Antonio Garufi +7

Protoplanetary disks with large inner dust cavities are thought to host massive planetary or substellar companions. These disks show asymmetries and rings in the millimeter continu…

Stellar clustering shapes the architectures of planetary systems

Andrew J. Winter, J. M. Diederik Kruijssen, Steven N. Longmore +1

Planet formation is generally described in terms of a system containing the host star and a protoplanetary disc, of which the internal properties (e.g. mass and metallicity) determ…
