On the possible relation between the Tunguska bolide and comet Encke

Autor: D. I. Steel, D.J. Asher

Publikováno v: Planetary and Space Science. 46:205-211

Almost two decades ago Ľ. Kresak (Bull. Astron. Inst. Czechoslov. 29, 129–134, 1978) suggested that the Tunguska bolide might be a fragment of comet Encke, a hypothesis that Z. Sekanina criticized in a publication a few years later (Astron. J. 88,

Near-Earth asteroid 1995 HM: a highly-elongated monolith rotating under tension?

Autor: D. I. Steel, A.D. Taylor, R. H. McNaught, G. J. Garradd, David Asher

Publikováno v: Planetary and Space Science. 45:1091-1098

Photometry of near-Earth asteroid 1995 HM obtained in 1995 June is reported. This object has dimensions of at most a few hundred metres. The 85 observations result in a lightcurve with an amplitude of at least two magnitudes, indicating a highly elon

A new method for the measurement of meteor speeds: The pre-tophase technique

Autor: D. I. Steel, M. A. Cervera, W.G. Elford

Publikováno v: Radio Science. 32:805-816

In this paper we describe a new technique for measuring the speeds of individual meteors based upon the variation of the phase received in specular reflections from the meteor train prior to the meteoroid reaching the point of closestapproach to the

On the origin of Comet Encke

Autor: D. I. Steel, D. J. Asher

Publikováno v: Monthly Notices of the Royal Astronomical Society. 281:937-944

Numerical integrations are performed on test-particle orbits similar to those of 2PlEncke and (6063) Jason. For purely gravitational integrations, or integrations with non-gravitational forces applied of a magnitude similar to those currently observe

The orbital dispersion of the macroscopic Taurid objects

Autor: D. I. Steel, D. J. Asher

Publikováno v: Monthly Notices of the Royal Astronomical Society. 280:806-822

If the Taurid Complex asteroids (plus 2PlEncke) are derived from the fragmentation of a giant comet over the past 20-30 kyr, as we have suggested elsewhere, then we need to identify some mechanism which could cause the observed dispersion in semimajo
