Impact of measurable physical phenomena on contact thermal comfort
EPJ Web of Conferences, 2017 Cabin HVAC (Heating Ventilation and Air-conditioning) systems have become an essential part of personal vehicles as demands for comfortable transport are still rising. In fact, 85 % of the car trips in Europe are shorter than 18 km and last only up to 30

Planetesimal Impact Vapor Plumes and Nebular Shocks Form Chondritic Mixtures
The Planetary Science JournalThe origin of chondrules and the chondritic sedimentary rocks that dominate the meteoritic record is a long-standing problem in planetary science. Here, we develop a physical model for the formation of chondritic mixtures as an outcome of vaporizing ...

The Planetary Science JournalWe investigated the relationship between microporosity, impact deformation, and aqueous alteration in the CM chondrite Murchison using high-resolution (1.86 μ m/voxel) X-ray computed tomography (XCT) combined with a pressurized xenon gas infiltration ...

Cavitating Bubbles in Condensing Gas as a Means of Forming Clumps, Chondrites, and Planetesimals
The Astrophysical Journal LettersVaporized metal, silicates, and ices on the verge of recondensing into solid or liquid particles appear in many contexts: behind shocks, in impact ejecta, and within the atmospheres and outflows of stars, disks, planets, and minor bodies.

Charged Ejecta Clouds from Granular Beds after Slow Impacts
The Planetary Science JournalLow-velocity impacts are a significant process on all planetary surfaces, from rebounding particles on asteroids to saltating grains on Earth. Due to triboelectric effects, the material involved can be charged. We carried out experiments to study the net

The Population of Young Craters on the Moon: New Catalog and Spatial and Temporal Analysis
The Planetary Science JournalWe present a new catalog of the Moon’s rayed and rocky craters from 5 to 130 km in diameter. Using data from the Lunar Reconnaissance Orbiter and the JAXA Kaguya/Selene missions, we identify 571 unique craters with albedo, maturity, and/or thermophysical

Evaluating Lunar Crater Ejecta Maturation across Wavelengths
The Planetary Science JournalEjecta blankets of young lunar craters provide an important window into the maturation processes of material at the lunar surface. As freshly exposed material degrades, the signature of that material changes in remote sensing data.

Collisional Capture of an Intact Moon Depends on Strength
The Astrophysical Journal LettersThe canonical giant impact hypothesis suggests that the proto-Earth’s collision with a differentiated Mars-sized planet, Theia, produced an iron-poor debris disk that accreted to form the Moon.

Predictions of Imminent Earth Impactors Discovered by LSST
The Astrophysical JournalImminent impactors are natural bodies discovered in space before impacting the Earth. They provide a rare opportunity to characterize individual near-Earth objects (NEOs) in great detail as asteroids in space, meteors in Earth’s atmosphere, and ...
