Roberto Gorelli points our attention at some recently published meteor related papers.

Lunar impact flashes

This paper will be published in the Monthly Notices of the Royal Astronomical Society: “Temperatures of lunar impact flashes: mass and size distribution of small impactors hitting the Moon.” by C. Avdellidou and J. Vaubaillon.

This paper presents an analysis of the observed lunar impact flashes caused by objects in the cm to dm size range. A possible link with individual meteoroid streams is considered.

The Geminid parent body: (3200) Phaethon

This paper appeared in Planetary & Space Science, Special Issue on Asteroid (3200) Phaethon and Meteoroids: “Arecibo Radar Observations of Near-Earth Asteroid (3200) Phaethon During the 2017 Apparition”, by Patrick A. Taylor, Edgard G. Rivera-Valentín, Lance A.M. Benner, Sean E. Marshall, Anne K. Virkki, Flaviane C.F. Venditti, Luisa F. Zambrano-Marin, Sriram S. Bhiravarasu, Betzaida Aponte-Hernandez, Carolina Rodriguez Sanchez-Vahamonde and Jon D. Giorgini.

This paper sketches a picture based on radar observations of asteroid (3200) Phaethon, the parent body of the Geminids.

Sun approaching asteroids and meteor streams

The third paper appears in Astronomy and Astrophysics: “Debris of asteroid disruptions close to the Sun”, by Quanzhi Ye and Mikael Granvik.

The paper describes the mechanism of heat driven disruption of rocky objects with small perihelion distances and how these can be associated to known Sun approaching meteor streams.
