Injection of Oort Cloud Comets: The Fundamental Role of Stellar Perturbations
We present Monte Carlo simulations of the dynamical evolution of the Oort cloud over the age of the Solar System, using an initial sample of one million test comets without any cloning. Our model includes perturbations due to the Galactic tide (radial and vertical) and passing stars. We present the first detailed analysis of the injection mechanism into observable orbits by comparing the comple...
متن کاملPhotometric stellar variation due to extra-solar comets
We performed numerical simulations of stellar occultations by extra-solar cometary tails. We find that extra-solar comets can be detected by the apparent photometric variations of the central stars. In most cases, the light curve shows a very peculiar “rounded triangular” shape. However, in some other cases, the curve can mimic a planetary occultation. Photometric variations due to comet occult...
متن کاملOrder statistics and heavy-tail distributions for planetary perturbations on Oort cloud comets
Aims. This paper tackles important aspects of comets dynamics from a statistical point of view. Existing methodology uses numerical integration for computing planetary perturbations for simulating such dynamics. This operation is highly computational. It is reasonable to wonder whenever statistical simulation of the perturbations can be much more easy to handle. Methods. The first step for answ...
متن کاملPerturbations to Stellar Structure in 2 D : Stellar Rotation and Heating in X - ray Binaries
We have developed a numerical code with which we study the effects of 2D perturbations on stellar structure. We present new numerical and analytical results on the heating of a main-sequence star in a binary system by its companion.
متن کاملPerturbations of spherical stellar systems during flyby encounters
We study the internal response of a galaxy to an unbound encounter and present a survey of orbital parameters covering typical encounters in different galactic environments. Overall, we conclude that relatively weak encounters by low-mass interloping galaxies can cause observable distortions in the primaries. The resulting asymmetries may persist long after the interloper is evident. We focus o...
