For realistic parameters (Qg ∼ 10– 30; Σd/Σg ∼ 0.015–0.15), the four densities obey ρ∗I < ρ∗Sekiya < ρ∗Roche ρ∗II . (17) The smallest three densities in this hierarchy are fixed multiples of the reference density ρ† = M∗/r3 (with coefficients ∼1/2...
Jianheng, on the other hand, posits that the physical parameters needed to classify the mechanisms behind hydrodynamic escape are simple. You just have to think about the characteristics of the planets and stars involved, the researcher says, such as their masses, radii, and the orbital separation...
We will give numerical estimates for parameters of the microlensing effect. If the distance between a dark body and the Sun is equal to ∼10kpc, then the angular size of Einstein cone of the dark body with a solar mass is equal to ∼0.″001 and its linear size is equal to about...

Often, it is useful to describe the different parameters of the earth's gravity field by a series of spherical or ellipsoidal harmonic functions (cf., the article “Global Gravity” in this volume). This description is often referred to as the spectral form, and it is really the only pract...

An example for such a magnification pattern is shown in Figure10. It is determined with the parameters of image A of the quadruple quasar Q2237+0305 (surface mass densityκ= 0.36; external shearγ= 0.44). Color indicates the magnification: blue is relatively low magnification (slightly demagnif...
