Irrigation and Drainage, EarlyView.ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Resonant Chains and the Convergent Migration of Planets in Protoplanetary Disks
The Astronomical JournalAn increasing number of compact planetary systems with multiple planets in a resonant chain have been detected. The resonant chain must be maintained by convergent migration of the planets due to planet–disk interactions if it is formed before the ...

Journal of Quaternary Science, EarlyView.ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

Resolving the disk-halo degeneracy using planetary nebulae
, 2016 The decomposition of the 21 cm rotation curve of galaxies into contribution from the disk and dark halo depends on the adopted mass to light ratio (M/L) of the disk.

Mind the Kinematics Simulation of Planet–Disk Interactions: Time Evolution and Numerical Resolution
The Astrophysical JournalPlanet–disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated.

The Journal of Wildlife Management, EarlyView.We use ecological niche model predictions across the next 3 decades for 263 forest‐dependent, terrestrial, vertebrate species of conservation concern in the Southeastern Appalachians under 4 future climate scenarios. We overlay these predictions with a collaborative conservation plan to determine if the priority map successfully represents potential ...

Forming Planetary Cores in a Turbulent Non-Isothermal Disk [PDF]
, 2011 Non-Isothermal disks have been shown to have regions where the net torque on a planet is positive, leading to outward migration of the planet. When a region with negative torque is directly exterior to this, planets in the inner region migrate outwards ...

Leaky Dust Traps in Planet-embedded Protoplanetary Disks
The Astrophysical JournalFrom the survival of dust disks for a few Myr to the establishment of chemical dichotomy, dust traps are expected to play a pivotal role in sculpting protoplanetary disks and the early planet formation process.

Angular momentum of planet-forming disks: Implications for infall-driven misalignments
Astronomy & AstrophysicsContext. A significant fraction (≳30%) of planet-forming disks and planetary systems are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism responsible for these misalignments remains unclear. Aims.
