“…Our paper is similar to recent similar studies of the relationship between various meteoroid streams and their parent bodies, i.e., cometary (Hajdukova et al 2015;Ishiguro et al 2015;Kornoš et al 2015;Rudawska et al 2016;Abedin et al 2015Abedin et al , 2017Abedin et al , 2018Babadzhanov et al 2017;Jenniskens et al 2017;Šegon et al 2017) and lately also asteroidal (Babadzhanov et al 2015a,b;Jopek 2015;Jopek & Williams 2015;Rudawska & Vaubaillon 2015;Olech et al 2016;Wiegert et al 2017;Dumitru et al 2018;Sergienko et al 2018a,b;Ye 2018;Guennoun et al 2019;Ryabova et al 2019). Some authors have attempted to work out or improve a method of prediction of particular shower, often on the basis of known parent body (Koten & Vaubaillon 2015;Ryabova 2016;Sugar et al 2017;Vaubaillon 2017;Ryabova & Rendtel 2018a,b).…”

Aims. We study the meteoroid stream of the long-period comet C/1975 T2 (Suzuki-Saigusa-Mori). This comet was suggested as the parent body of the established λ-Ursae Majorid meteor shower, No. 524. Methods. We modeled 32 parts of a theoretical meteoroid stream of the parent comet considered. Each of our models is characterized with a single value of the evolutionary time and a single value of the strength of Poynting-Robertson effect. The evolutionary time ranges from 10 000 to 80 000 yr. It is the period during which the evolution of the stream part is followed. In each model, the dynamical evolution of 10 000 test particles was then followed, via a numerical integration, from the time of the modeling up to the present. At the end of the integration, we analyzed the mean orbital characteristics of particles in the orbits that approach the Earth’s orbit, which thus enabled us to predict a shower related to the parent comet. The predicted shower was subsequently compared with its observed counterparts. We separated the latter from the databases of real meteors. As well, we attempted to identify the predicted shower to a shower recorded in the International Astronomical Union Meteor Data Center (IAU MDC) list of all showers. Results. Almost all modeled parts of the stream of comet C/1975 T2 are identified with the corresponding real shower in three video-meteor databases. No real counterpart is found in the IAU MDC photographic or radio-meteor data. In the IAU MDC list of showers and in our current study, this shower is identified with the established λ-Ursae Majorid shower, No. 524. Hence, our modeling confirms the results of previous authors. At the same time we exclude an existence of other meteor shower associated with C/1975 T2.

“…It has been found that 289P/Blanpain is still weakly active, at a level that is too low to replenish the Phoenicid stream (Jewitt, 2006). , 2006;Ryabova, 2008;Kasuga, 2009). It has been proposed that these bodies and streams were formed as a result of thermal disintegration of a much larger progenitor Kasuga (2009).…”

Meteor showers from active asteroids and dormant comets in near-Earth space: A review

Small bodies in the solar system are conventionally classified into asteroids and comets. However, it is recently found that a small number of objects can exhibit properties of both asteroids and comets. Some are more consistent with asteroids despite episodic ejections and are labeled as "active asteroids", while some might be aging comets with depleting volatiles. Ejecta produced by active asteroids and/or dormant comets are potentially detectable as meteor showers at the Earth if they are in Earth-crossing orbits, allowing us to retrieve information about the historic activities of these objects. Meteor showers from small bodies with low and/or intermittent activities are usually weak, making shower confirmation and parent association challenging. We show that statistical tests are useful for identifying likely parent-shower pairs. Comprehensive analyses of physical and dynamical properties of meteor showers can lead to deepen understanding on the history of their parents. Meteor outbursts can trace to recent episodic ejections from the parents, and "orphan" showers may point to historic disintegration events. The flourish of NEO and meteor surveys during the past decade has produced a number of high-confidence parent-shower associations, most have not been studied in detail. More work is needed to understand the formation and evolution of these parent-shower pairs.

“…While the orbital relationship between the two bodies is indeed debated (see, e.g., Ryabova et al 2019), the objects are similar in so many ways that a shared origin is often assumed in spite of and the Geminids. In the absence of other unknown processes operating on these bodies now or in the recent past, we conclude that the least complicated interpretation of the data is simply that the objects are only similar by chance.…”

The relationship between the Near-Earth Objects (3200) Phaethon and (155140) 2005 UD is unclear. While both are parents to Meteor Showers, (the Geminids and Daytime Sextantids, respectively), have similar visible-wavelength reflectance spectra and orbits, dynamical investigations have failed to find any likely method to link the two objects in the recent past. Here we present the first near-infrared reflectance spectrum of 2005 UD, which shows it to be consistently linear and red-sloped unlike Phaethon's very blue and concave spectrum. Searching for a process that could alter some common starting material to both of these end states, we hypothesized that the two objects had been heated to different extents, motivated by their near-Sun orbits, the composition
