Sharp Eccentric Rings in Planetless Hydrodynamical Models of Debris Disks [PDF]
, 2013 Exoplanets are often associated with disks of dust and debris, analogs of the Kuiper Belt in our solar system. These "debris disks" show a variety of non-trivial structures attributed to planetary perturbations and utilized to constrain the properties of

Sustainable Metal Recovery From E‐Waste: Exploring Greener Leachates in Hydrometallurgical Processes
MetalMat, EarlyView.Recycling of electronic waste to synthesize valuable metals using green leachate. ABSTRACT The accumulation of electronic waste (e‐waste) poses environmental hazards and leads to the loss of valuable metals such as gold, silver, copper, and rare earth elements.

The Longest-period Young Transiting Exoplanets—A Duo of Puffy Giants inside a Debris Disk
The Astrophysical Journal LettersWe identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA’s Transiting Exoplanet Survey Satellite (TESS), and a second dip, spotted by the Next ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

An Inclined, Eccentric Planet and an Inner Debris Disk Could Reproduce AU Microscopii Structure
The Astrophysical JournalThe debris disk orbiting the M star AU Microscopii (AU Mic) has a series of large-scale clumps that move away from the star at high velocities above the midplane on the southeast side.

Polymer Composites, EarlyView.Schematic illustration of the experimental procedure of the specimens. ABSTRACT This research work investigated the effect of the cyclic thermo‐hygrometric aging regime between −20°C and +40°C with 0–400 cycles on the reciprocating tribological properties of fused deposition modeling (FDM) printed polylactic acid (PLA) and the same material reinforced ...

MINDS: Detection of an Inner Gas Disk Caused by Evaporating Bodies around HD 172555
The Astrophysical JournalMechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planetary composition.

Two-stage formation of the Moon from accreting fragmentation and resonance captures
Astronomy & AstrophysicsContext. In the canonical Moon-forming model, a Mars-sized object collided with Earth to produce a disk of debris from which the Moon is believed to have accreted. Aims.
