Trojan asteroids and co-orbital dust ring of Venus
Yang-Bo Xu, Lei Zhou, Christoph Lhotka +2
The long-standing co-orbital asteroids have been thought to be the possible source of zodiacal dust ring around the orbit of Venus, but inconsistent conclusions on the orbital stab…
Investigating Mercury's Environment with the Two-Spacecraft BepiColombo Mission
A. Milillo, M. Fujimoto, G. Murakami +76
The ESA-JAXA BepiColombo mission will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric dyna…
Laplace-like resonances with tidal effects
A. Celletti, E. Karampotsiou, C. Lhotka +2
We generalize the Laplace resonance among three satellites, S1, S2 , and S3, by considering different ratios of the mean-longitude variations. These resonances, which we call Lapla…
Tadpole type motion of charged dust in the Lagrange problem with planet Jupiter
Christoph Lhotka, Lei Zhou
We investigate the dynamics of charged dust interacting with the interplanetary magnetic field in a Parker spiral type model and subject to the solar wind and Poynting-Robertson ef…
Dynamics of charged dust in the orbit of Venus
Lei Zhou, Christoph Lhotka, Catalin Gales +2
We study the dynamics of co-orbital dust in the inner solar system, i.e. the role of the solar radiation pressure, Poynting-Robertson effect, solar wind, and the interplanetary mag…
Asteroid migration due to the Yarkovsky effect and the distribution of the Eos family
Yang-Bo Xu, Li-Yong Zhou, Christoph Lhotka +1
Based on a linearized model of the Yarkovsky effect, we investigate in this paper the dependence of the semimajor axis drift of a celestial body on its size, spinning obliquit…
Resonances in the Earth's Space Environment
Alessandra Celletti, Catalin Gales, Christoph Lhotka
We study the presence of resonances in the region of space around the Earth. We consider a massless body (e.g, a dust particle or a small space debris) subject to different forces:…
Charged dust close to outer mean-motion resonances in the heliosphere
Christoph Lhotka, Catalin Gales
We investigate the dynamics of charged dust close to outer mean-motion resonances with planet Jupiter. The importance of the interplanetary magnetic field on the orbital evolution…
Gravity field and solar component of the precession rate and nutation coefficients of Comet 67P Churyumov-Gerasimenko
Christoph Lhotka, Stefan Reimond, Jean Souchay +1
The aim of this study is first to determine the gravity field of the comet 67P Churyumov-Gerasimenko and second to derive the solar component of the precession rate and nutation co…
Charged dust grain dynamics subject to solar wind, Poynting-Robertson drag, and the interplanetary magnetic field
Christoph Lhotka, Philippe Bourdin, Yasuhito Narita
We investigate the combined effect of solar wind, Poynting-Robertson drag, and the frozen-in interplanetary magnetic field on the motion of charged dust grains in our solar system.…
Poynting-Robertson drag and solar wind in the space debris problem
Christoph Lhotka, Alessandra Celletti, Catalin Gales
We analyze the combined effect of Poynting-Robertson and solar wind drag on space debris. We derive a model within Cartesian, Gaussian and Hamiltonian frameworks. We focus on the g…
The effect of Poynting-Robertson drag on the triangular Lagrangian points
Christoph Lhotka, Alessandra Celletti
We investigate the stability of motion close to the Lagrangian equilibrium points L4 and L5 in the framework of the spatial, elliptic, restricted three- body problem, subject to th…
The influence of orbital dynamics, shape and tides on the obliquity of Mercury
Benoit Noyelles, Christoph Lhotka
Earth-based radar observations of the rotational dynamics of Mercury (Margot et al. 2012) combined with the determination of its gravity field by MESSENGER (Smith et al. 2012) give…
The orbit of 2010 TK7. Possible regions of stability for other Earth Trojan asteroids
Rudolf Dvorak, Christoph Lhotka, Liyong Zhou
Recently the first Earth Trojan has been observed (Mainzer et al., ApJ 731) and found to be on an interesting orbit close to the Lagrange point L4 (Connors et al., Nature 475). In…
An Overview of the 13:8 Mean Motion Resonance between Venus and Earth
Ákos Bazsó, Veresa Eybl, Rudolf Dvorak +2
It is known since the seminal study of Laskar (1989) that the inner planetary system is chaotic with respect to its orbits and even escapes are not impossible, although in time sca…
