The paper on thermal stress in Geminids was published in Astronomy & Astrophysics
On 28 January, the international journal Astronomy and Astrophysics has published a paper by a team of authors, led by Tomáš Henych, on the role of thermal stress in fragmentation of Geminid meteoroids. The paper is based on observations of the European Fireball Network and also on video observations of fainter meteors, numerical modeling of fragmentation and thermal stress in meteoroids. The popular summary of results of this paper for the series “What We’re Working On” at the Astronomical Institute’s website was prepared by Michal Švanda (in Czech only).
