Stellar and Planetary Aberration
For some time the writer has been seeking improved understanding of the several kinds of aberration—these being rather superficially explained in most texts, particularly texts of relativity theory. Indeed, in some of the more highly regarded of these (e.g., Møller 1972) the phenomenon of stellar aberration is so slightingly treated that use of the formulas provided would literally yield wrong ...
متن کاملTidal instability in stellar and planetary binary systems
In this paper, we combine theoretical and experimental approaches to study the tidal instability in planetary liquid cores and stars. We demonstrate that numerous complex modes can be excited depending on the relative values of the orbital angular velocity Ωorbit and of the spinning angular velocity Ωspin, except in a stable range characterized by Ωspin/Ωorbit ∈ [−1; 1/3]. Even if the tidal def...
متن کاملA Catalog of Multiplicity among Bright Stellar Systems
We consider the multiplicity of stellar systems with (combined) magnitude brighter than 6.00 in Hipparcos magnitudes. We identify 4559 such bright systems (including the Sun), and the frequencies of multiplicities 1, 2, . . . , 7 are found to be 2718, 1437, 285, 86, 20, 11 and 2. We discuss the uncertainties, which are substantial. We also consider the distributions of periods of orbits and sub...
متن کاملMultiplicity in Early Stellar Evolution
Many reviews have been written on pre-main-sequence binaries over the past 25 years, e.g., Reipurth (1988), Zinnecker (1989), Mathieu (1994), and Goodwin (2010), and particular mention should be made of IAU Symposium No. 200 (Zinnecker and Mathieu, 2001), which is still today a useful reference. Most recently, Duchêne and Kraus (2013) review the binarity for stars of all masses and ages. Stimul...
متن کاملDynamical Interactions of Planetary Systems in Dense Stellar Environments
We study dynamical interactions of star-planet binaries with other single stars. We derive analytical cross sections for all possible outcomes and confirm them with numerical scattering experiments. We find that a wide mass ratio in the binary introduces a region in parameter space that is inaccessible to comparable-mass systems, in which the nature of the dynamical interaction is fundamentally...
