The origin of short-period comets
Icarus, 1990Abstract Recent work has shown that if short-period comets predominantly occur as a result of planetary “captures” of long-period comets, the relevant source flux of nearly parabolic orbits must involve comets with perihelia in the range 5–30 AU, significantly beyond the region in which the flux is observationally constrained. The numbers and orbital

New edition of the catalogue of short-period comets
Earth, Moon, and Planets, 1995The Institute of Theoretical Astronomy in St. Petersburg and the Astronomical Institute in Bratislava are preparing a new edition of the Catalogue of short-period comets. This edition will be supplemented by short-period comets discovered after the year 1983 and comprises some new features, e. g. the evolution of orbital elements between the years 1750

Hypothetical evolutions of short-period comets
Symposium - International Astronomical Union, 1996The hypothetical model of capture I consider is as follows: a comet with an initial conic orbit, meets close to one of its vertices an outer planet and generates one or several little comets (crossing of the Roche limit) with an elliptic orbit. This initial vertex always remains one of the vertices of the captured orbit by the Solar System.

Unnumbered Short-Period Comets
2017The following lists comets having periods of less than 25 years that have either been discovered in recent years or for which a short-period orbit has recently been calculated. Most of these objects will probably be recovered at future apparitions and be given permanent numbers.

Thermal evolution and differentiation of a short-period comet
Planetary and Space Science, 1993Abstract The evolution of the subsurface layers of a short-period comet has been studied. The structure and composition of the surface layers due to sublimation recondensation phenomena, to gas diffusion processes through the pore system and to the ejection of dust particles have been investigated in detail. The nucleus has been modelled as a mixture

The distribution of short-period comet magnitudes
Earth, Moon, and Planets, 1987Short-period comets with P ≤ 15 yr represent one of the most complete comet samples. The magnitude distribution of these comets was analysed using a maximum likelihood method. The brightness (magnitude) index for the comets with H 10 ≤ 11 mag was estimated together with the large sample errors and found to be 0.62 ± 0.09.

Orbits of Short Period Comets Captured from the Oort Cloud
Earth, Moon, and Planets, 1996Oort cloud comets occasionally obtain orbits which take them through the planetary region. The perturbations by the planets are likely to change the orbit of the comet. We model this process by using a Monte Carlo method and cross sections for orbital changes, i.e.

Numbered Observable Short-Period Comets
2017The following list includes all numbered comets of short period cataloged until June 2016 that have been observed at their most recent favorable apparition and that, presumably, still existed as of that date.

Meteor contribution by short-period comets
1988The contribution of P/Halley and other comets to the meteor streams are discussed. Particular attention is given to the meteoric production by P/Encke as the potential major contributor to the meteoric complex in the inner part of the solar system. The density and total mass of the meteoric stream associated with P/Encke is derived, taking into account
