In the latest Gaia third data release one can find extremely small proper motion components for the star HD 7977. This, together with the radial velocity measurement lead to the co…
Important stellar perturbers found during the StePPeD database update based on Gaia EDR3 data
Piotr A. Dybczyński, Filip Berski, Jakub Tokarek +3
Context. In 2020, the initial version of the Stellar Potential Perturbers Database (StePPeD) was presented with the aim to deliver up-to-date information on the stars and stellar s…
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…
