Can the Gravitational Effect of Planet X be Detected in Current-era Tracking of the Known Major and Minor Planets? [PDF]

open access: yesThe Planetary Science Journal, 2022
Using Fisher information matrices, we forecast the uncertainties σ M on the measurement of a “Planet X” at heliocentric distance d X via its tidal gravitational field’s action on the known planets.

FindPOTATOs: Minor Planet Observation Linking Software [PDF]

open access: yesThe Planetary Science Journal
For minor planet observations to be archived and used by the scientific community, observations of individual objects must be linked together into groups called tracklets.

Chaos over Order: Mapping 3D Rotation of Triaxial Asteroids and Minor Planets [PDF]

open access: yes, 2022
Celestial bodies approximated with rigid triaxial ellipsoids in a two-body system can rotate chaotically due to the time-varying gravitational torque from the central mass.

Observational Completion Limit of Minor Planets from the Asteroid Belt to Jupiter Trojans [PDF]

open access: yesThe Planetary Science Journal, 2020
With the growing numbers of asteroids being discovered, identifying an observationally complete sample is essential for statistical analyses and for informing theoretical models of the dynamical evolution of the solar system.

Enrichment of the HR 8799 planets by minor bodies and dust [PDF]

open access: yesAstronomy & Astrophysics, 2020
Are minor bodies and dust delivering volatile and/or refractory materials in exoplanetary systems?  Around ~20% of the nearest stars are found to host analogues of the main asteroid belt and the Kuiper belt.

Calibration of the angular momenta of the minor planets in the solar system [PDF]

open access: yesAstronomy & Astrophysics, 2019
Aims. We aim to determine the relative angle between the total angular momentum of the minor planets and that of the Sun-planets system, and to improve the orientation of the invariable plane of the solar system. Methods. By utilizing physical parameters

Computation of asteroid proper elements: Recent advances [PDF]

open access: yesSerbian Astronomical Journal, 2017
The recent advances in computation of asteroid proper elements are briefly reviewed. Although not representing real breakthroughs in computation and stability assessment of proper elements, these advances can still be considered as important improvements

Computation of asteroid proper elements on the Grid [PDF]

open access: yesSerbian Astronomical Journal, 2009
A procedure of gridification of the computation of asteroid proper orbital elements is described. The need to speed up the time consuming computations and make them more efficient is justified by the large increase of observational data expected from the

Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets

open access: yesThe Astronomical Journal, 2023
We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG ...
