Encapsulation Based Method for Natural Frequency Identification of Deployable Solar Arrays with Multiple Plates

open access: yesShock and Vibration, 2021
The ground modal test is an important approach to the natural frequency of solar arrays to support the attitude control of spacecraft. However, for the batch production of small satellites, the accuracy and efficiency of traditional ground modal testing ...

ANALYSIS OF SELF – GRAVITATING PLANETARY SATELLITES IN THE SOLAR SYSTEM

open access: yesOdessa Astronomical Publications, 2016
As of today there have been more than 180 planetary satellites discovered in the Solar system, and the number of outer moons found continues to grow. Most of those natural satellites have insufficient mass and are able to retain their shape only due to ...

Gravity-induced seismicity modulation on planetary bodies and their natural satellites

open access: yesScientific Reports
Ground-based monitoring of seismicity and modulation by external forces in the field of planetary seismology remains equivocal due to the lack of natural observations.

The Influence of Central Body Tides on Catastrophic Disruptions of Close-in Planetary Satellites

open access: yesThe Astrophysical Journal
We model the outcomes of catastrophic disruptions on small, gravity-dominated natural satellites, accounting for the tidal potential of the central body, which is neglected in classical disruption scaling laws. We introduce the concept of ${Q}_{\,\rm{TD}\

An Efficient Method for Measuring the Color of a Natural Satellite with Astrometric Applications

open access: yesThe Astronomical Journal
The Gaia DR3 catalog released in 2022 contains precise broadband photometry for more than one billion stars in the G , BP, and RP passbands, which is very useful for calibrating the differential color refraction (DCR) effect in ground-based observations.

Gaia Data Release 3: The Solar System survey [PDF]

open access: yesAstronomy & Astrophysics, 2022
The third data release by the Gaia mission of the European Space (DR3) is the first release to provide the community with a large sample of observations for more than 150 thousand Solar System objects, including asteroids and natural planetary satellites.

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 ...

The wedge-pentahedra method (WPM): Topographic reduction of local terrain in the context of solar system surface gravimetry and robotic exploration

open access: yesFrontiers in Space Technologies, 2022
In classical gravimetry, different corrections are applied, e.g. to correct for the measurement elevation above a reference plane and the gravitational attraction of the material lying between the measurement point and reference plane.

Quantification of tidal parameters from Solar System data [PDF]

open access: yesCelestial mechanics & dynamical astronomy, 2016
Tidal dissipation is the main driver of orbital evolution of natural satellites and a key point to understand the exoplanetary system configurations. Despite its importance, its quantification from observations still remains difficult for most objects of
