Enhanced Size Uniformity for Near-resonant Planets
The Astrophysical Journal, 2023 Super-Earths within the same close-in, compact planetary system tend to exhibit a striking degree of uniformity in their radius, mass, and orbital spacing, and this “peas-in-a-pod” phenomenon itself serves to provide one of the strongest constrains on ...

Testing a hypothesis of the ν Octantis planetary system [PDF]
, 2012 We investigate the orbital stability of a putative Jovian planet in a compact binary \nu Octantis reported by Ramm et al. We re-analyzed published radial velocity data in terms of self-consistent Newtonian model and we found stable best-fit solutions ...

Streaming Torque with Turbulent Diffusion
The Astrophysical JournalFast type I migration of (proto)planets poses a challenging problem for the core accretion formation scenario. We found that the dust-induced “Streaming Torque” (ST) may slow down or even reverse the planet migration in Q. Hou & C. Yu.

The diversity of planetary system architectures: contrasting theory with observations [PDF]
, 2011 In order to explain the observed diversity of planetary systems architectures and relate this primordial diversity with the initial properties of the disc where they were born, we develop a semi-analytical model for computing planetary system formation ...

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler
Advanced Materials, EarlyView.An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

VLT/NACO astrometry of the HR 8799 planetary system - L′-band observations of the three outer planets [PDF]
, 2011 Context. HR 8799 is so far the only directly imaged multiple exoplanet system. The orbital configuration would, if better known, provide valuable insight into the formation and dynamical evolution of wide-orbit planetary systems. Aims.

Formation of Protoplanet Systems and Diversity of Planetary Systems
The Astrophysical Journal, 2002 We investigate the formation of protoplanet systems from planetesimal disks by global (N = 5000 and 10,000 and 0.5 AU 2. The growth timescale increases with a but decreases with Σ1. Based on the oligarchic growth model and the conventional Jovian planet formation scenario, we discuss the diversity of planetary systems.
