Dynamical Heating in the Martian Thermosphere

Journal of Geophysical Research: Planets, Volume 128, Issue 6, June 2023., 2023
Abstract Dynamical heating and cooling are prominent features of planetary atmospheres resulting in thermospheric structures on Venus, Earth and Mars. The purpose of this study is to determine the location and amplitude of localized heating regions in the Martian thermosphere, confirm that they occur in regions of wind convergence and compare the ...

Using the potassium‐argon laser experiment (KArLE) to date ancient, low‐K chondritic meteorites

Meteoritics &Planetary Science, Volume 58, Issue 4, Page 591-611, April 2023., 2023
Abstract Several laboratories have been investigating the feasibility of in situ K‐Ar dating for use in future landing planetary missions. One drawback of these laboratory demonstrations is the insufficient analogy of the analyzed analog samples with expected future targets. We present the results obtained using the K‐Ar laser experiment (KArLE) on two

Compositions and Interior Structures of the Large Moons of Uranus and Implications for Future Spacecraft Observations

Journal of Geophysical Research: Planets, Volume 128, Issue 1, January 2023., 2023
Abstract The five large moons of Uranus are important targets for future spacecraft missions. To motivate and inform the exploration of these moons, we model their internal evolution, present‐day physical structures, and geochemical and geophysical signatures that may be measured by spacecraft.

CRESST

EAS Publications Series, 2009
The CRESST-II direct Dark Matter search is located in the Gran Sasso underground laboratories, Italy. CaWO4 crystals are used as scintillating targets for WIMP (weakly interacting massive particle) interactions. They are operated as cryogenic calorimeters in combination with a second cryogenic detector used to measure the scintillation light produced ...

CRESST – status and future

Nuclear Physics B - Proceedings Supplements, 2007
We present results on WIMP dark matter interaction, obtained using cryogenic phonon-scintillation detectors. The targets are CaWO4 scintillating crystals with phonon sensors, while scintillation is detected with an associated cryogenic light detector.

The Role of Atmospheric Exchange in False‐Positive Biosignature Detection

Journal of Geophysical Research: Planets, Volume 127, Issue 3, March 2022., 2022
Abstract Saturn's Moon Titan receives volatiles into the top of its atmosphere—including atomic oxygen—sourced from cryovolcanoes on Enceladus. Similar types of atmosphere exchange from one body to another, such as O2 and O3 sourced from TRAPPIST‐1 d, could be introduced into the upper atmosphere of TRAPPIST‐1 e and might be interpreted as ...

Solitary Magnetic Structures Developed From Gyro‐Resonance With Solar Wind Ions at Mars and Earth

Geophysical Research Letters, Volume 49, Issue 3, 16 February 2022., 2022
Abstract We investigate solitary magnetic structures in the foreshock of Mars and Earth. The structures exhibit pulse‐like magnetic field and density enhancements along with plasma heating and local solar wind (SW) ion reflection. The structures at Mars resemble the foreshock structures developed from ultra‐low‐frequency electromagnetic waves gyro ...
