Analytical direct planetary perturbations on the orbital motion of satellites
(2013-01-01)
An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...

Molecular chemistry and the missing mass problem in planetary nebulae
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Context. Detections of molecular lines, mainly from H-2 and CO, reveal molecular material in planetary nebulae. Observations of a variety of molecules suggest that the molecular composition in these objects differs from ...

The influence of planetary attractions on the solar tachocline
(Elsevier, 2012-05)
We present a physical analysis of the occasionally forwarded hypothesis that solar variability, as shown in the various photospheric and outer solar layer activities, might be due to the Newtonian attraction by the planets. ...
