Galactic and stellar perturbations of long period comet motion -- Practical considerations
Piotr A. Dybczyński, Sławomir Breiter
Context. Due to our increasing knowledge on the Galactic and stellar neighborhood of the Solar System, modern long-period comet motion studies have to take into account both stella…
Analytical solution of the Colombo top problem
J. Haponiak, S. Breiter, D. Vokrouhlicky
The Colombo top is a basic model in the rotation dynamics of a celestial body moving on a precessing orbit and perturbed by a gravitational torque. The paper presents a detailed st…
The Lissajous-Kustaanheimo-Stiefel transformation
Slawomir Breiter, Krzysztof Langner
The Kustaanheimo-Stiefel transformation of the Kepler problem with a time-dependent perturbation converts it into a perturbed isotropic oscillator of 4-and-a-half degrees of freedo…
Kustaanheimo-Stiefel transformation with an arbitrary defining vector
Slawomir Breiter, Krzysztof Langner
Kustaanheimo-Stiefel (KS) transformation depends on the choice of some preferred direction in the Cartesian 3D space. This choice, seldom explicitly mentioned, amounts typically to…
Analysis of the rotation period of asteroids (1865) Cerberus, (2100) Ra-Shalom, and (3103) Eger - search for the YORP effect
J. Durech, D. Vokrouhlicky, A. R. Baransky +28
The spin state of small asteroids can change on a long timescale by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropically scatter…
Stress field and spin axis relaxation for inelastic triaxial ellipsoids
Slawomir Breiter, Agata Rozek, David Vokrouhlicky
A compact formula for the stress tensor inside a self-gravitating, triaxial ellipsoid in an arbitrary rotation state is given. It contains no singularity in the incompressible medi…
YORP effect with anisotropic radiation
Slawomir Breiter, David Vokrouhlicky
The influence of optical scattering and thermal radiation models an the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is studied. Lambertian formulation is compared with Hapk…
YORP torques with 1D thermal model
Slawomir Breiter, Przemyslaw Bartczak, Maria Czekaj
A numerical model of the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect for objects defined in terms of a triangular mesh is described. The algorithm requires that each surfac…
YORP torque as the function of shape harmonics
S. Breiter, H. Michalska
The second order analytical approximation of the mean YORP torque components is given as an explicit function of the shape spherical harmonics coefficients for a sufficiently regul…
The long-term stability of extrasolar system HD 37124. Numerical study of resonance effects
Krzysztof Gozdziewski, Slawomir Breiter, Wojciech Borczyk
We describe numerical tools for the stability analysis of extrasolar planetary systems. In particular, we consider the relative Poincare variables and symplectic integration of the…
