Bridging Unstratified and Stratified Simulations of the Streaming Instability for Grains
Jeonghoon Lim, Stanley A. Baronett, Jacob B. Simon +4
The streaming instability (SI), driven by aerodynamic coupling between solids and the gas under a global radial pressure gradient, concentrates solids and facilitates planetesimal…
Probing Conditions for Strong Clumping by the Streaming Instability: Small Dust Grains and Low Dust-to-gas Density Ratio
Jeonghoon Lim, Jacob B. Simon, Rixin Li +5
The streaming instability (SI) is a leading mechanism for concentrating solid particles into regions dense enough to form planetesimals. Its efficiency in clumping particles depend…
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…
