“…A94, page 5 of 7 A&A 598, A94 (2017) Valsecchi et al (1999) used the quantities of U and cos θ to identify meteor showers with orbits having different q, e, i, Ω and ω as possibly originating from the same body, due to secular perturbations on the same meteoroid stream. Here, U is the geocentric velocity of the meteoroids when crossing the Earth's orbit…”

The evolution of the nominal orbits of comet 96/Machholz 1 and the near-Earth asteroid (196256) 2003 EH1 under the effects of gravitational perturbations from the major planets was investigated over a time interval of 28 000 yr. Several criteria for measuring the differences in orbits were used to determine when the orbits were most similar to each other and this was found to be approximately 9500 ago. This supports the hypothesis that the comet 96P/Machholz 1, the near-Earth asteroid (196256) 2003 EH1, and the Quadrantid meteoroid stream form a complex of related objects.

“…Several empirical metrics in orbital elements are defined for finding Taurid parent bodies that cluster using asteroids and comets Valsecchi et al 1999;Jopek et al 2008). Based on different criteria, like "D-criterion", several authors have determined the asteroids belonging to TC Babadzhanov 2001;Babadzhanov et al 2008).…”

Context. The Taurid Complex is a massive stream of material in the inner part of the Solar System. It contains objects spanning the range of 10 −6 -10 3 m, considered by some authors to have a common cometary origin. The asteroids belonging to Taurid Complex are on Apollo type orbit, with most of them being flagged as potentially hazardous asteroids. In this context, understanding the nature and the origin of this asteroidal population is not only of scientific interest but also of practical importance. Aims. We aim to investigate the surface mineralogy of the asteroids associated with Taurid Complex using visible and near-infrared spectral data. Compositional linking between these asteroids and meteorites can be derived based on the obtained spectra. Methods. We obtained spectra of six of the largest asteroids (2201, 4183, 4486, 5143, 6063, and 269690) associated with Taurid complex. The observations were made with the IRTF telescope equipped with the spectro-imager SpeX. Their taxonomic classification is made using Bus-DeMeo taxonomy. The asteroid spectra are compared with the meteorite spectra from the Relab database. Mineralogical models were applied to determine their surface composition. All the spectral analysis is made in the context of the already published physical data. Results. Five of the objects studied in this paper present spectral characteristics similar to the S taxonomic complex. The spectra of ordinary chondrites (spanning H, L, and LL subtypes) are the best matches for these asteroid spectra. The asteroid (269690) 1996 RG3 presents a flat featureless spectrum which could be associated to a primitive C-type object. The increased reflectance above 2.1 microns constrains its geometrical albedo to a value around 0.03. Conclusions. While there is an important dynamical grouping among the Taurid Complex asteroids, the spectral data of the largest objects do not support a common cometary origin. Furthermore, there are significant variations between the spectra acquired until now.

“…Several similarity functions have been proposed: D S H the orbital D-criterion introduced by Southworth and Hawkins (1963), its modifications by Drummond (1981), Jopek (1993), Valsecchi et al (1999), and Jenniskens (2008) and the D V function defined in the domain of the vectorial heliocentric orbital elements (Jopek et al (2008)). The threshold, D c is used to test the similarity among two…”
