Atmospheric Dynamics on Strongly Irradiated Jovian Planets - Strona vii
The small points on the orbital diagram show the position of the planet at one-hour intervals; the larger globes (labeled 1 through 4) show the position of the planet at times t = — 19h, Oh, +19h, +38h relative to periastron. The black poles on ...

Planets Outside the Solar System: Theory and Observations - Strona 99
Plot of the spatial distribution of the periastron of a set of bodies located between 70 and 90 AU and perturbed by a planet on eccentric orbit (Me = 3.10"Me, ep = 0.05, ap = 30 AU). We see that the density of bodies with periastron in the ...

The Formation and Early Evolution of Stars: From Dust to Stars and ...
periastron separation of the two stars is only 8 stellar radii. [519]. This has a few interesting consequences. One consequence is that as long as the two stars are not near periastron passage, they indeed behave like moderately active CTTS.

Established by Unger (1856) from the Russchiefer shales in Thuringia, Germany, Periastron was subsequently identified from the New Albany Shale in Indiana and Kentucky and the Lydiennes formation in southern France (Scott and Jeffrey, ...

Rotation and Accretion Powered Pulsars - Strona 258
One diagnostic is the behavior of Hα line — the emission site for which is believed to be the Be-star disk — as the neutron star passes around the periastron, accompanied by enhanced X-ray emission due to enhanced accretion. If the disk is ...

The HESS observations of this source in 2004, from a few days prior the periastron to several months after the periastron passage, revealed a TeV gamma-ray signal with a high statistical significance. The flux was found to vary significantly on ...

Time, Space, Stars and Man: The Story of the Big Bang - Strona 235
Figure 20.6 The modification of an elliptical orbit in a freely-rotating medium showing the effect of forces at periastron and apastron. At periastron the effect is to modify the orbit towards the green form. At apastron the effect is to modify the orbit ...
