On the extrasolar multi-planet system around HD160691
Krzysztof Gozdziewski, Andrzej J. Maciejewski, Cezary Migaszewski
We re-analyze the precision radial velocity (RV) observations of HD160691 (mu Ara) by the Anglo-Australian Planet Search Team. The star is supposed to host two Jovian companions (H…
Orbital configurations and dynamical stability of multi-planet systems around Sun-like stars HD 202206, 14 Her, HD 37124 and HD 108874
Krzysztof Gozdziewski, Maciej Konacki, Andrzej J. maciejewski
We perform a dynamical analysis of the recently published radial velocity (RV) measurements of a few solar type stars which host multiple Jupiter-like planets. In particular, we re…
Orbital solutions to the HD160691 (mu Arae) Doppler signal
Krzysztof Gozdziewski, Maciej Konacki, Andrzej J. Maciejewski
We perform a dynamical analysis of the recently updated set of the radial velocity (RV) measurements of the HD160691 (mu Arae). The kinematic, 2-Keplerian model of the measurements…
Group analysis of structure equations for stars in radiative and convective equilibrium
Marek Szydlowski, Andrzej J. Maciejewski
It is proposed to use the Lie group theory of symmetries of differential equations to investigate the system of equations describing a static star in a radiative and convective equ…
Where is the second planet in the HD 160691 planetary system?
K. Gozdziewski, M. Konacki, A. J. Maciejewski
The set of radial velocity measurements of the HD 160691 has been recently published by Jones et.al 2002 (MNRAS). It reveals a linear trend that indicates a presence of the second…
The Janus head of the HD 12661 planetary system
Krzysztof Gozdziewski, Andrzej J. Maciejewski
In this work we perform a global analysis of the radial velocity curve of the HD 12661 system. Orbital fits that are obtained by the genetic and gradient algorithms of minimization…
Improved timing formula for the PSR B1257+12 planetary system
Maciej Konacki, Andrzej J. Maciejewski, Alex Wolszczan
We present a new analysis of the dynamics of the planetary system around the pulsar B1257+12. A semi-analytical theory of perturbation between terrestrial-mass planets B and C is d…
Frequency decomposition of astrometric signature of planetary systems
Maciej Konacki, Andrzej J. Maciejewski, Alex Wolszczan
We present theoretical analysis of the astrometric searches for extrasolar planets with the Space Interferometry Mission (SIM). Particularly, we derive a model for the future measu…
Resonance in PSR B1257+12 Planetary System
Maciej Konacki, Andrzej J. Maciejewski, Alex Wolszczan
In this paper we present a new method that can be used for analysis of time of arrival of a pulsar pulses (TOAs). It is designated especially to detect quasi-periodic variations of…
Frequency Analysis of Reflex Velocities of Stars with Planets
Maciej Konacki, Andrzej J. Maciejewski
Since it has become possible to discovery planets orbiting nearby solar-type stars through very precise Doppler-shift measurements, the role of methods used to analyze such observa…
