FIRST-based survey of Compact Steep Spectrum sources, III. MERLIN and VLBI observations of subarcsecond-scale objects
Andrzej Marecki, Magdalena Kunert-Bajraszewska, Ralph E. Spencer
According to a generally accepted paradigm, small intrinsic sizes of Compact Steep Spectrum (CSS) radio sources are a direct consequence of their youth, but in later stages of thei…
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…
About putative Neptune-like extrasolar planetary candidates
Krzysztof Gozdziewski, Cezary Migaszewski
We re-analyze the precision radial velocity (RV) data of HD188015, HD114729, HD190360, HD147513 and HD208487. All these stars are supposed to host Jovian companions in long-period…
Nonlinear stability of relativistic sheared planar jets
M. Perucho, J. M. Marti, M. Hanasz
The linear and non-linear stability of sheared, relativistic planar jets is studied by means of linear stability analysis and numerical hydrodynamical simulations. Our results exte…
Signatures of restarted activity in core-dominated, triple radio sources selected from the FIRST survey
A. Marecki, P. Thomasson, K. -H. Mack +1
Signatures of the re-occurrence of activity in radio-loud AGNs, indicated either by the so-called double-double or X-shaped structures, have been observed in a number of radio sour…
Trojan pairs in the HD 128311 and HD 82943 planetary systems?
Krzysztof Gozdziewski, Maciej Konacki
Two nearby stars, HD 128311 and HD 82943, are believed to host pairs of Jupiter-like planets involved in a strong first order 2:1 mean motion resonance (MMR). In this work we reana…
