Coupled biogenic and soil emissions amplify heatwave-driven secondary pollution [PDF]

open access: yesEnvironmental Science and Ecotechnology
Global air pollution policies have drastically lowered anthropogenic emissions, yet climate change threatens regional air quality through poorly understood natural feedbacks.

Satellite formation flying for an interferometry mission [PDF]

open access: yes, 2005
The autonomous formation flying of multiple spacecraft to replace a single large satellite will be an enabling technology for many future missions. In this research, the current status of formation flying missions and technologies is determined, and ...

The Development of high fidelity linearized J2 models for satellite formation flying control [PDF]

open access: yes, 2005
The inclusion of the linearized J2 effect in the Hill equations of relative motion gives greater insight into satellite formation flying dynamics, and the opportunity to investigate alternative feedback control strategies for the station keeping task.

Exploring the Recycling Model of Phobos Formation: Rubble-pile Satellites

open access: yesThe Astronomical Journal, 2023
Phobos is the target of the return sample mission Martian Moons eXploration by JAXA that will analyze in great detail the physical and compositional properties of the satellite from orbit, from the surface, and in terrestrial laboratories, giving clues ...

Tidal Truncation of Circumplanetary Disks Fails above a Critical Disk Aspect Ratio

open access: yesThe Astrophysical Journal, 2023
We use numerical simulations of circumplanetary disks to determine the boundary between disks that are radially truncated by the tidal potential and those where gas escapes the Hill sphere. We consider a model problem, in which a coplanar circumplanetary

Nature versus nurture: what regulates star formation in satellite galaxies? [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
We use our state-of-the-art Galaxy Evolution and Assembly (GAEA) semi-analytic model to study how and on which time-scales star formation is suppressed in satellite galaxies. Our fiducial stellar feedback model, implementing strong stellar driven outflows, reproduces relatively well the variations of passive fractions as a function of galaxy stellar ...

Early Stages of Galilean Moon Formation in a Water-depleted Environment

open access: yesThe Astrophysical Journal Letters, 2023
A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto ...
