Control of Magnetopause Flux Rope Topology by Non-local Reconnection

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Dayside magnetic reconnection between the interplanetary magnetic field and the Earth’s magnetic field is the primary mechanism enabling mass and energy entry into the magnetosphere.

Geological evolution and habitable environment of Mars: Progress and prospects

open access: yes地球与行星物理论评, 2021
Mars is the most similar planet to the Earth in the solar system. Due to its diverse aqueous history and the capability to preserve ancient life, Mars has been one of the major planets explored by deep space missions.

Timing and Abundance of Clathrate Formation Control Ocean Evolution in Outer Solar System Bodies: Challenges of Maintaining a Thick Ocean within Pluto

open access: yesThe Planetary Science Journal, 2023
Abstract Clathrate hydrates may represent a sizable fraction of material within the icy shells of Kuiper Belt objects and icy moons. They influence the chemical and thermal evolution of subsurface oceans by locking volatiles into the ice shell and by providing more thermal insulation than pure water ice.

The late accretion and erosion of Vesta’s crust recorded by eucrites and diogenites as an astrochemical window into the formation of Jupiter and the early evolution of the Solar System [PDF]

open access: yesIcarus, 2018
For decades the limited thickness of Vesta's basaltic crust, revealed by the link between the asteroid and the howardite-eucrite-diogenite family of meteorites, and its survival to collisional erosion offered an important constraint for the study of the early evolution of the Solar System.

Material Challenges and Alloy Selection for Particle/s‐CO2 Heat Exchangers in Concentrated Solar Power Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Combining supercritical CO2 (s‐CO2) cycles with particle‐based heat transfer media holds great potential in concentrated solar power plants but poses enormous material challenges. The particle/s‐CO2 heat exchanger must withstand extreme conditions, including high temperatures, pressures, CO2 corrosion, and erosion.

Moon formation and orbital evolution in extrasolar planetary systems - A literature review

open access: yesEPJ Web of Conferences, 2011
With over 450 extrasolar planets detected, the possibility of searching for moons of these planets is starting to be investigated. In order to make efficient use of limited observing resources, it would be useful if the types of moons that a given planet ...

Chondrule formation and evolution of the early solar system

open access: yesJournal of Mineralogical and Petrological Sciences, 2006
Chondrules are millimeter to sub-millimeter size silicate spherules that formed during localized and transient high-temperature events in the early solar system. Although it is not yet understood how chondrules formed, recent studies have provided important clues in understanding the physical conditions of chondrule formation.

Geomagnetic Storm‐Induced Plasma Density Enhancements in the Southern Polar Ionospheric Region: A Comparative Study Using St. Patrick's Day Storms of 2013 and 2015

open access: yesSpace Weather, 2020
The occurrence of St. Patrick's Day (17 March) geomagnetic storms during two different years (2013 and 2015) with similar solar flux levels but varying storm intensity provided an opportunity to compare and contrast the responses of the ionosphere ...
