Primordial or Secondary? Testing Models of Debris Disk Gas with ALMA
The Astrophysical Journal, 2023 The origin and evolution of gas in debris disks are still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed.

Open Astronomy, 2021 In this paper, the mechanisms of star formation and the formation of the equatorial gas and dust disk of protostars are considered. The viscous dynamics of the interstellar matter of gas and dust disks is mainly determined by perturbations of the matter ...

Triggering rainfall intensities for post-wildfire debris flows in the Sonoran Desertscrub plant community [PDF]
E3S Web of Conferences, 2023 Wildfire makes landscapes more vulnerable to debris flows by reducing soil infiltration capacity and decreasing vegetation cover. The extent to which fire affects debris-flow processes depends on the severity of the fire, the climatology of intense ...

RZ Piscium Hosts a Compact and Highly Perturbed Debris Disk
The Astrophysical Journal, 2023 RZ Piscium (RZ Psc) is well known in the variable star field because of its numerous irregular optical dips in the past 5 decades, but the nature of the system is heavily debated in the literature.

Testing the Interaction between a Substellar Companion and a Debris Disk in the HR 2562 System
The Astronomical Journal, 2023 The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interaction between a substellar companion and a dusty disk.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorus: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorus (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.
