Shepherding Miorita and its flock: A group of near-Earth asteroids driven by apsidal and von Zeipel-Lidov-Kozai secular resonances. A source of low-perihelion asteroids
R. de la Fuente Marcos, C. de la Fuente Marcos, O. Văduvescu
Context. Secular resonances can control the dynamical evolution of near-Earth asteroids (NEAs) and, in some cases, lead to increased orbital stability. Asteroid 622577 Miorita (201…

Discovery and physical characterization as the first response to a potential asteroid collision: The case of 2023 DZ2
Marcel M. Popescu, O. Văduvescu, Julia de León +15
Near-Earth asteroids (NEAs) that may evolve into impactors deserve detailed threat assessment studies. Early physical characterization of a would-be impactor may help in optimizing…
Distant trans-Neptunian object candidates from NASA's TESS mission scrutinized: fainter than predicted or false positives?
C. de la Fuente Marcos, R. de la Fuente Marcos, O. Vaduvescu +1
NASA's Transiting Exoplanet Survey Satellite (TESS) is performing a homogeneous survey of the sky from space in search of transiting exoplanets. The collected data are also being u…
Twisted extreme trans-Neptunian orbital parameter space: statistically significant asymmetries confirmed
C. de la Fuente Marcos, R. de la Fuente Marcos
Asymmetric debris discs have been found around stars other than the Sun; asymmetries are sometimes attributed to perturbations induced by unseen planets. The presence or absence of…
Memories of past close encounters in extreme trans-Neptunian space: Finding unseen planets using pure random searches
C. de la Fuente Marcos, R. de la Fuente Marcos
Context. The paths followed by the known extreme trans-Neptunian objects (ETNOs) effectively avoid direct gravitational perturbations from the four giant planets, yet their orbital…
Constraining the orientation of the spin axes of extrasolar minor bodies 1I/2017 U1 (`Oumuamua) and 2I/Borisov
C. de la Fuente Marcos, R. de la Fuente Marcos
Context. The orientation of the spin axis of a comet is defined by the values of its equatorial obliquity and its cometocentric longitude of the Sun. These parameters can be comput…
Physical characterization of 2020 AV2, the first known asteroid orbiting inside Venus orbit
M. Popescu, J. de León, C. de la Fuente Marcos +8
The first known asteroid with the orbit inside that of Venus is 2020~AV. This may be the largest member of a new population of small bodies with the aphelion smaller than 0.7…
On the orbital evolution of 2020 AV2, the first asteroid ever observed to go around the Sun inside the orbit of Venus
C. de la Fuente Marcos, R. de la Fuente Marcos
The innermost section of the Solar system has not been extensively studied because minor bodies moving inside Earth's orbit tend to spend most of their sidereal orbital periods at…
Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
Javier Licandro, Carlos de la Fuente Marcos, Raul de la Fuente Marcos +3
The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area focused on highly active objects, those with small perihelion distances or examples of…
Dancing with Venus in the shadow of the Earth: a pair of genetically related near-Earth asteroids trapped in a mean-motion resonance
C. de la Fuente Marcos, R. de la Fuente Marcos
YORP-induced fission events may form dynamically coherent pairs or even families of asteroids. The outcome of this process is well documented among members of the main asteroid bel…
Waiting to make an impact: A probable excess of near-Earth asteroids in 2018 LA-like orbits
C. de la Fuente Marcos, R. de la Fuente Marcos
Context. The discovery and tracking of 2018 LA marks only the third instance in history that the parent body of a fireball has been identified before its eventual disintegration in…
A Fruit of a Different Kind: 2015 BP519 as an Outlier among the Extreme Trans-Neptunian Objects
C. de la Fuente Marcos, R. de la Fuente Marcos
A number of intriguing patterns have been identified in the distributions of the orbital elements of the known extreme trans-Neptunian objects or ETNOs --those with semimajor axis…
