Universidad de Zaragoza Orbital analysis in the gravitational potential of elongated asteroids 2024 Access copy available to the general public Unrestricted This work studies the motion around irregular elongated asteroids through two approaches. Firstly, it revisits the dipole-segment model, identifying families of periodic orbits for asymmetric mass distribution. Additionally, a new model incorporating variable density for elongated asteroids is introduced and compared to the dipole-segment model. Several families of periodic orbits have been found through continuation of planar orbits and out-of-plane bifurcation processes, obtaining results in agreement with previous studies about the dynamics around irregular asteroids. This highlights the relevance of simple mathematical models in studying asteroid dynamics and the importance of accounting for density and geometric properties. Although the families of periodic orbits studied in this work are not comprehensively sampled, they constitute an example of the variety of orbits that can be followed by a particle orbiting the asteroid, helping us to better understand the dynamics around these elongated bodies. info:eu-repo/grantAgreement/ES/DGA/E24-23R info:eu-repo/grantAgreement/ES/MICINN/PID2020-117066GB-I00 info:eu-repo/grantAgreement/ES/MICINN PRE2021-099561 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 1.5 2024 ASTRONOMY & ASTROPHYSICS 52 / 84 = 0.619 2024 Q3 T2 0.378 2024 Space and Planetary Science 2024 Q3 Astronomy and Astrophysics 2024 Q3 2.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tresaco, Eva Universidad de Zaragoza (orcid)0000-0003-4859-7224 Riaguas, Andrés 2005 595 Universidad de Zaragoza Dpto.
