Dynamical Interactions and Mass Loss within the Uranian System

open access: yesThe Planetary Science Journal, 2023
The origin and evolution of planetary rings and moons remains an active area of study, particularly as they relate to the impact history and volatile inventory of the outer solar system.

The Planetary Mass–Radius Relation and Its Dependence on Orbital Period as Measured by Transit Timing Variations and Radial Velocities [PDF]

open access: yes, 2017
The two most common techniques for measuring planetary masses—the radial velocity (RV) and the transit timing variation (TTV) techniques—have been observed to yield systematically different masses for planets of similar radii.

Dead Zones as Thermal Barriers to Rapid Planetary Migration in Protoplanetary Disks

open access: yes, 2010
Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid ($\sim 10^5$ years) jeopardizing the existence of planetary systems.

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

A Search for Photometric Variability in the Young T3.5 Planetary-mass Companion GU Psc b [PDF]

open access: yes, 2017
We present a photometric J-band variability study of GU Psc b, a T3.5 co-moving planetary-mass companion (9–13 ) to a young (∼150 Myr) M3 member of the AB Doradus Moving Group. The large separation between GU Psc b and its host star (42″) provides a rare

Planetary nebulae after common-envelope phases initiated by low-mass red giants

open access: yes, 2013
It is likely that at least some planetary nebulae are composed of matter which was ejected from a binary star system during common-envelope (CE) evolution.

Retrospective Review on Reticular Materials: Facts and Figures Over the Last 30 Years

open access: yesAdvanced Materials, EarlyView.
To shape the future course of research in reticular materials, this work reflects on the progress over the past 30 years, complemented by input from the community of 228 active researchers through a global, crowdsourced survey: ranging from demographics, how it works, publish and interact, to highlights on both academic and industrial milestones, as ...

Analyses of Multiple Balmer Emission Lines from Accreting Brown Dwarfs and Very Low Mass Stars

open access: yesThe Astronomical Journal
A planetary growth rate, i.e., the mass accretion rate, is a fundamental parameter in planet formation, as it determines a planet's final mass. Planetary mass accretion rates have been estimated using hydrogen lines, based on the models originally ...

Hydrodynamic simulations of captured protoatmospheres around Earth-like planets

open access: yes, 2015
Young terrestrial planets, when they are still embedded in a circumstellar disk, accumulate an atmosphere of nebula gas. The evolution and eventual evaporation of the protoplanetary disk affect the structure and dynamics of the planetary atmosphere ...

Planet formation from the ejecta of common envelopes [PDF]

open access: yes, 2014
The close binary system NN Serpentis must have gone through a common envelope phase before the formation of its white dwarf. During this phase, a substantial amount of mass was lost from the envelope.
