The Formation and Early Evolution of Stars: From Dust to ...
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.

the synchrotron X-radiation which, however, is not observed. Just opposite, the X-
ray lightcurve contains a clear minimum at the periastron. It has been claimed ...

Atmospheric Dynamics on Strongly Irradiated Jovian Planets
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

nature of the interaction between the two stars? How large are the tidal forces
and is there any mass exchange?

Binaries as Tracers of Stellar Formation
An approximate scale length for such interactions can be obtained by plotting
curves of constant periastron separation in the e-log P plane. In Figure 2 we
show the PMS eccentricity distribution and a curve of constant periastron
separation ...

= projected periastron. The line NN' is the line of nodes. Notice that A is not in the
focus of the apparent ellipse. the observed elements are connected to the true ...

Eta Carinae and the Supernova Impostors
The orientation of the shock structure may be significantly distorted by orbital
motion [70,74]; • Radiative cooling may destabilize the shock near periastron,
possibly causing a general disruption or collapse of the X-ray source region [25,
61]; ...
