Can Moons Have Moons? [PDF]

open access: yesMNRAS, 2019 483, L80, 2018
Each of the giant planets within the Solar System has large moons but none of these moons have their own moons (which we call ${\it submoons}$). By analogy with studies of moons around short-period exoplanets, we investigate the tidal-dynamical stability of submoons.

Yearling proportion correlates with habitat structure in a boreal forest landbird community [PDF]

open access: yesPeerJ, 2020
Landbird vital rates, such as productivity and adult survivorship, can be estimated by modeling mist-netting capture data. The proportion in which an adult breeding bird is 1 year of age (a “yearling”), however, has been studied only minimally in a few ...

Spectrophotometric and Topographic Correlations within the Mare Ingenii Swirl Region: Evidence for a Highly Mobile Lunar Regolith

open access: yesThe Planetary Science Journal, 2023
The spectrophotometric properties of two study areas in the Ingenii swirl region show that the combined effects of multiple processes are required to explain the regolith’s mineralogical and physical properties.

The Role of the Commercial Space Industry within the US National Security under the Trump Administration

open access: yesВестник Московского Университета. Серия XXV: Международные отношения и мировая политика, 2021
The US space activities from their inception have been closely connected with the private sector. However, only in 2010s private space companies have come to play a prominent role not only on the global market of space services but in the field of ...

Transfer design between neighborhoods of planetary moons in the circular restricted three-body problem [PDF]

open access: yesCelestial Mechanics & Dynamical Astronomy 133, 36 (2021), 2021
Given the interest in future space missions devoted to the exploration of key moons in the solar system and that may involve libration point orbits, an efficient design strategy for transfers between moons is introduced that leverages the dynamics in these multi-body systems.

Large planets may not form fractionally large moons [PDF]

open access: yesNature Communications 13, 568 (2022), 2023
One of the unique aspects of Earth is that it has a fractionally large Moon, which is thought to have formed from a Moon-forming disk generated by a giant impact. The Moon stabilizes the Earth's spin axis at least by several degrees and contributes to Earth's stable climate.
