Planetary systems formation and the diversity of extrasolar systems [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWith the end of answer questions as, how common are planetary systems like our own in the Universe? and What is the diversity of planetary systems that we could find in the universe?, we develop a semi-analytical model for computing planetary systems formation and consider different initial conditions for generating a large sample of planetary ...

Planet formation with envelope enrichment: new insights on planetary diversity [PDF]
, 2016 We compute, for the first time, self-consistent models of planet growth including the effect of envelope enrichment. The change of envelope metallicity is assumed to be the result of planetesimal disruption or icy pebble sublimation.

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus
Arthritis Care &Research, EarlyView.Objective Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined the following: (1) associations between economic insecurities and PROs, and (2) the impact of screening and addressing economic ...

Implications of Differentiated Late Accretion for the Volatile Inventory of the Bulk Silicate Earth
The Planetary Science JournalEarth is believed to have acquired its highly siderophile element (HSE) inventory through the late accretion of ∼0.3%–0.5% of its mass in chondrite-like materials, following the main stage of its growth. Late accretion, particularly if it originated from

Stellar Outbursts and Chondrite Composition
The Astrophysical Journal, 2023 The temperatures of observed protoplanetary disks are not sufficiently high to produce the accretion rate needed to form stars, nor are they sufficient to explain the volatile depletion patterns in CM, CO, and CV chondrites and terrestrial planets.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Ringed versus Ringless Worlds: How Poynting–Robertson Drag Shapes Rings across the Solar System
The Astrophysical Journal LettersPlanetary rings are not only ubiquitous around the giant planets in the outer solar system, but have also been discovered around several small distant bodies. In contrast, no rings have been observed around any inner solar system objects.

Hybrid Metal–Carbon Ink for Printed Stretchable Temperature Sensors
Advanced Engineering Materials, EarlyView.We prepare conductive inks for temperature sensing with silver flakes and carbon or graphite flakes in a silicone elastomer matrix. Silver dominates the temperature‐dependent conductivity, while the carbon filler network ensures the stability of the conductive pathways and retains function under strain.

The cosmochemistry of planetary systems [PDF]
Nature Reviews ChemistryPlanets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influences every aspect of planetary composition, including their overall ...
