Non-principal axis rotation in binary asteroid systems and how it weakens the BYORP effect [PDF]
Icarus (New York, N.Y. 1962), 2021 Using viscoelastic mass/spring model simulations, we explore tidal evolution and migration of compact binary asteroid systems. We find that after the secondary is captured into a spin-synchronous state, non-principal axis rotation in the secondary can be

Mass-shedding Activities of Asteroid (3200) Phaethon Enhanced by Its Rotation [PDF]
Astrophysical Journal, 2020 Asteroid (3200) Phaethon, a B-type asteroid, has been active during its perihelion passages. This asteroid is considered to be a source of the Geminid meteor stream.

On the secondary’s rotation in a synchronous binary asteroid [PDF]
Monthly notices of the Royal Astronomical Society, 2020 This article studies the secondary’s rotation in a synchronous binary asteroid system in which the secondary enters the 1:1 spin-orbit resonance.

Physical Properties of the Young Asteroid Pair 2010 UM26 and 2010 RN221
The Astronomical Journal, 2023 The main belt asteroids 458271 (2010 UM26) and 2010 RN221 share almost identical orbital elements, and currently appear as comoving objects ∼30″ apart in the plane of the sky.

Performance Constraints of All-Perovskite Tandem Solar Cells in Low-Intensity, Low-Temperature Environments. [PDF]
Adv MaterAll‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Asteroid Deflection by Leveraging Rotational Self-Energy [PDF]
Journal of Spacecraft and Rockets, 2021 A novel concept for the deflection of rotating asteroids is presented, based on the conversion of the asteroid rotational kinetic energy into translational kinetic energy. Such conversion is achieved using an orbital siphon, a tether-connected chain of masses, arranged vertically from the asteroid surface, which exploits the rotation of the asteroid ...

Frontiers in Astronomy and Space Sciences, 2022 The authors explore the possibility that near-earth, rubble pile asteroids might be used as habitats for human settlement by increasing their rotation to produce spin gravity. Using previously published scaling by Maindl et al.

Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
The Planetary Science Journal, 2022 Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes ...

The physical and dynamical characteristics of the asteroid 4940 Polenov [PDF]
Serbian Astronomical Journal, 2021 The asteroid (1986 QY4) 4940 Polenov is the first Solar system object whose 3D shape is determined using the observations from the newly built Astronomical Station Vidojevica (ASV).
