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 ...

Masses and Densities of Dwarf Planet Satellites Measured with ALMA

open access: yesThe 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.

Constraining the Nature of Dark Matter with the Star-formation History of the Faintest Local Group Dwarf Galaxy Satellites [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract Λ warm dark matter (ΛWDM), realized by collisionless particles of 1–3 keV, has been proposed as an alternative scenario to Λ-Cold-Dark Matter (ΛCDM) for the dwarf galaxy scale discrepancies. We present an approach to test the viability of such WDM models using star-formation histories (SFHs) of the dwarf spheroidal galaxies ...

Typology of forest hunting grounds [PDF]

open access: yesСибирский 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

open access: yesThe 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 ...
