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

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

Masses and Densities of Dwarf Planet Satellites Measured with ALMA
The Planetary Science Journal, 2023 We have used the Atacama Large Millimeter/submillimeter Array to measure precise absolute astrometric positions and detect the astrometric wobble of dwarf planet Orcus and its satellite Vanth over a complete orbit.

Typology of forest hunting grounds [PDF]
Сибирский лесной журнал, 2023 The analysis of the developed classification schemes of forest hunting grounds is given. Previously, forest typology was taken as a basis with a 4-level division (category-class-group of types-type).

Jupiter’s Early Luminosity May Have Driven off Io’s Initial Water Inventory
The Planetary Science Journal, 2023 After its formation, Jupiter was substantially more luminous than it is at the present day (10 ^4 times). Right after formation, the inner satellites Io and Europa would have received an order-of-magnitude larger incoming flux from Jupiter, than solar ...

Remote Study of Aufeis along the ‘Power of Siberia’ Gas Pipeline in the Aldan River Basin [PDF]
E3S Web of Conferences, 2020 The ‘Power of Siberia’ gas pipeline route passes through the territories of South-West and South Yakutia, where the natural conditions are characterized by severe climatic, complex engineering geological and geocryological conditions.

The Astrophysical Journal Letters, 2023 The quenched fraction of satellite galaxies is aligned with the orientation of the halo’s central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

Remote Sensing, 2023 This study presents a novel approach for the detection of contrails in satellite imagery using a convolutional neural network (CNN). Contrails are important to monitor because their contribution to climate change is uncertain and complex.
