Bifurcated Evolutionary Pathways in Multiplanet Systems Driven by Misaligned Protoplanetary Disks

open access: yesThe Astrophysical Journal Letters
Stellar obliquities, or spin–orbit angles, prevalent in exoplanet systems, can impose important constraints on their formation and evolution histories.

Triboelectric nanogenerators for vehicle intelligent cockpits

open access: yesFlexMat, EarlyView.
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Formation of a planetary Laplace resonance through migration in an eccentric disk

open access: yes, 2018
Context. Orbital mean motion resonances in planetary systems originate from dissipative processes in disk-planet interactions that lead to orbital migration.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets. II. The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model

open access: yesThe Astrophysical Journal
Although dust constitutes only about 1% of the mass in a protoplanetary disk, recent studies reveal its substantial impact on the torques experienced by low- and intermediate-mass planetary cores.

Low-Energy Cosmic Rays and Associated MeV Gamma-Ray Emissions in the Protoplanetary System

open access: yesUniverse
Low-energy cosmic rays (LECRs) play a crucial role in the formation of planetary systems, and detecting and reconstructing the properties of early LECRs is essential for understanding the mechanisms of planetary system formation.

Integrating belowground bud bank dynamics into grassland monitoring and management

open access: yesGrassland Research, EarlyView.
Adaptive Management of Grassland Ecosystems: A Bud Bank Perspective. Abstract Belowground bud banks are the core regenerative organs of perennial herbaceous plants, playing an irreplaceable role in population persistence, community assembly, and ecosystem restoration.

Migration of the outermost objects in planetary systems

open access: yes, 2010
The outermost bodies of planetary systems embedded in a planetesimal disk migrate much faster than the other planets. The outward migration of such bodies is self-sustained by supplying fresh planetesimals up to the edge of the disk.

Extreme variability of the V488 Persei debris disk

open access: yes, 2021
V488 Persei is the most extreme debris disk known in terms of the fraction of the stellar luminosity it intercepts and reradiates. The infrared output of its disk is extremely variable, similar in this respect to the most variable disk known previously ...

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk

open access: yesThe Astrophysical Journal
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main-sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm continuum data for Fomalhaut (with a synthesized angular resolution of 0 $
