Protostellar disk formation in low- and high-mass star formation AbstractThe new generation of interferometers provide unprecedented constraints on the protostellar disk formation process. Observations indicate that most protostellar disks have a small extent at the Class 0 stage and that disks...
Le 14 février 2020 De 10h30 à 12h00 Anna Lisa Varri University of Edinburgh Our traditional interpretative picture of the internal dynamics of ancient star clusters has been recently revolutionized by a series of discoveries about their chemical, structural, and kinematic properties....
Le 7 février 2020 De 10h30 à 12h00 Laurent Pagani Observatoire de Paris In the ‘70s, while several groups were trying to measure various isotopic ratios in dark clouds (13C/12C, 18O/17O/16O,...), it was quickly realized that the D/H ratio of several molecules was...
Le 31 janvier 2020 De 10h30 à 12h00 Francesca Fragkoudi MPA Garching Embedded in the chemo-dynamical properties of stellar populations in the inner Milky Way (MW), are clues to the formation history of our Galaxy. By combining these properties with tailored N-body...
Le 24 janvier 2020 De 10h30 à 12h00 Bernard Foing ESA/ESTEC C60 was discovered in 1985 from a mass spectrometer peak by Kroto, Curl, Smalley & al,, for which they got the Nobel Prize in Chemistry in 1996. It was then produced in macroscopic quantities by Kratschmer...
Le 17 janvier 2020 De 10h30 à 12h00 Gabriele Pezzulli ETH Zurich Galaxy formation models rely on mechanisms to keep the majority of baryons outside of the main body of galaxies. Different scenarios, however, make different predictions about where these "galactic missing...
Le 10 janvier 2020 De 10h30 à 12h00 Miroslav Filipovic Western Sydney University This is an exciting time for the discovery and study of supernova remnants (SNRs), which reflect a major process in the elemental enrichment of the interstellar medium (ISM). The study of this...
Le 20 décembre 2019 De 10h30 à 12h00 Allison Man University of Toronto A fundamental question in galaxy evolution is how galaxies acquire diverse colours and morphologies. The current paradigm suggests that massive galaxies experienced accelerated growth in the early Universe...
Le 13 décembre 2019 De 10h30 à 12h00 Nicolas Gillet ObAS The upcoming flood of data from radio 21cm and the launch of JWST (expected soon) will dramatically change our understanding of the early Universe and our understanding of the formation of galaxies. I will present the...
Le 6 décembre 2019 De 10h30 à 12h00 Ute Lisenfeld Universidad de Granada Galaxy interaction can affect strongly the star formation activity and the molecular gas content of galaxies. Frequently, interaction enhances both quantities, but this is not always the case. I will...
