How Eccentric is the Debris Disk of ϵ Eridani? ALMA Reveals a Near-circular Belt

The Astrophysical Journal
The nearby (3.2 pc) K2V star ϵ  Eridani hosts the closest detected debris disk and an exo-Jupiter analog ( ϵ  Eridani b). In this work, we reanalyse Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 (1.29 mm) observations of ϵ  Eridani to assess

Topics on Planet-Disk Interaction and Solar Convection

, 2019
In this thesis I focus on two topics: planet-disk interaction and solar convection. These two seemingly separate topics are connected via a similar separation of timescales. Planets excite spiral waves in their disks on fast timescales compared to the time for the disk to viscously adjust to the angular momentum deposited by those waves.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Constraining disk evolution prescriptions of planet population synthesis models with observed disk masses and accretion rates [PDF]

, 2019
While planets are commonly discovered around main-sequence stars, the processes leading to their formation are still far from being understood. Current planet population synthesis models, which aim to describe the planet formation process from the ...

Carbonization‐Controlled Porosity and Electron Transport in Molybdenum Oxide‐Carbide/Carbon Nanoflower Anodes

EcoEnergy, EarlyView.
Carbonization temperature regulates the pore structure of active materials, leading to distinct pore volumes and particle assemblies of MoO2/Mo2C‐C nanoflower composites. These material‐level structural features determine the degree of interparticle contact within the electrode, and thus, the effective electronic conductivity. The optimized M750 sample

Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.

Kinematic signatures of planet-disk interactions in vertical shear instability

Astronomy & Astrophysics
Context. Planets are thought to form inside weakly ionized regions of protoplanetary disks, where turbulence creates ideal conditions for solid growth. However, the nature of this turbulence is still uncertain. In fast cooling parts of this zone the vertical shear instability (VSI) can operate, inducing a low level of gas turbulence and large-scale gas

Concertos of planet-disk interactions: thermal and kinematic fingerprints [PDF]

Planets form in protoplanetary disks, where interactions with their natal environments shape disk evolution and leave observable signatures. High-resolution observations over the past decade have revealed substructures such as gaps, rings, and non ...

Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet’s Orbital Eccentricity

The Astrophysical Journal
Eccentric planets constitute a large population of the known exoplanets and may drive significant substructures in protoplanetary disks through planet–disk interactions if their eccentricities are excited early in the planet formation process.
