Formation of super-Earths around low-mass stars: evolution of an icy dead zone

Danilo A. Arturo Rodriguez, Rebecca G. Martin

Exoplanet observations show that close-in super-Earths are more common around M-dwarfs than around solar mass stars. Since the snow line in a protoplanetary disc plays a crucial ro…

Primordial planet spin driven by boundary layer effects in a decretion disc

Rebecca G. Martin, Stephen H. Lubow, David Vallet +4

Accretion of material from a protoplanetary disc on to a forming giant planet can spin the planet up to close to its breakup rate, , where $M_{…

Planet-disc interactions around eccentric binaries and misaligned ring formation

Rebecca G. Martin, Stephen H. Lubow

We explore the evolution of a giant planet that interacts with a circumbinary disc that orbits a misaligned binary by means of analytic models and hydrodynamical simulations. Plane…

The fraction of polar aligned circumbinary disks

Ted M. Johnson, Rebecca G. Martin, Stephen Lepp +1

Circumbinary gas disks that are misaligned to the binary orbital plane evolve toward either a coplanar or a polar-aligned configuration with respect to the binary host. The preferr…

Polar circumtriple planets and disks around misaligned hierarchical triple stars

Stephen Lepp, Rebecca G. Martin, Stephen H. Lubow

Observations of hierarchical triple star systems show that misalignments are common both between the angular momentum vector of the inner binary and the outer companion orbit, and…

Observational Signatures of a Previous Dynamical Instability in Multi-planet M-Dwarf Systems

Anna C. Childs, Alexa P. S. Hua, Rebecca G. Martin +2

We identify observational signatures suggesting a history of dynamical instability in 26 out of 34 M-dwarf multi-planet systems containing no large planets. These systems may have…

Shedding light on the origin of the broken misaligned circumtriple disk around GW Ori

Jeremy L. Smallwood, Stephen H. Lubow, Rebecca G. Martin +1

We revisit the origin of the observed misaligned rings in the circumtriple disk around GW Ori. Previous studies appeared to disagree on whether disk breaking is caused by the diffe…

Polar orbits around the newly formed Earth-Moon binary system

Stephen Lepp, Rebecca G. Martin, Stanley A. Baronett

We examine the dynamics and stability of circumbinary particles orbiting around the Earth-Moon binary system. The moon formed close to the Earth (semi-major axis $a_{EM}\approx 3\,…

On the origin of polar planets around single stars

Cheng Chen, Stanley A. Baronett, C. J. Nixon +1

The Rossiter-McLaughlin effect measures the misalignment between a planet's orbital plane and its host star's rotation plane. Around 10 of planets exhibit misalignments in the…

Inclination instability of circumbinary planets

Stephen H. Lubow, Anna C. Childs, Rebecca G. Martin

We analyze a tilt instability of the orbit of an outer planet in a two planet circumbinary system that we recently reported. The binary is on an eccentric orbit and the inner circu…

Warps and Breaks in Circumbinary Discs

Ian Rabago, Zhaohuan Zhu, Stephen Lubow +1

Disc warping, and possibly disc breaking, has been observed in protoplanetary discs around both single and multiple stars. Large warps can break the disc, producing multiple observ…
