Introduction: Up to now, only cometary dust from comet 1P/Halley has been analyzed in situ by mass spectrometry techniques. In contrast, numerous studies have been performed in the laboratory over interplanetary dust particles (IDPs) thought to be related to comets. Another discipline that addresses the study of the chemical composition of small meteoroids is meteor spectroscopy, which focuses ...

Comet P/Halley has been observed during its approach to perihelion at heliocentric distances R = I 1.0 AU and R = 8.2 AU. No extended coma is seen and limits can be placed on the fraction of the total light contributed by coma. The brightness of the comet varies on a short time scale. The variations may be due to transient activity or to rotation of the irregular nucleus. ,. 1984 Academic Pre',...

[1] Long-period planetary wave data derived from meteor wind observations recorded over a 12-year period with the SuperDARN radar at Halley, Antarctica, are presented and compared with the phase of the quasi-biennial oscillation (QBO) throughout the equatorial stratosphere. Enhanced planetary wave activity in the Antarctic upper mesosphere is found during the summer months, when the QBO in the ...

Recent advances in techniques of critical close reading historical texts can now be applied to records pre-telescopic celestial observations - allowing significant progress for analyzing and solving orbits past comets: we exemplify our method by the orbit comet AD 760 only with then identify it 1P/Halley. A detailed eyewitness record drawing a Syriac Chronicle Zuqnin (finished 775/6) was not ye...

We present a local convergence analysis of a Modified Halley-Like Method of high convergence order in order to approximate a solution of a nonlinear equation in a Banach space. Our sufficient convergence conditions involve only hypotheses on the first Fréchet-derivative of the operator involved. Earlier studies use hypotheses up to the third Fréchet-derivative [26]. Numerical examples are also ...
