Self-gravitating vortices in protoplanetary discs PhD defense by Steven Rendon Abstract Structures observed in protoplanetary discs could be due to large-scale vortices whose consequences on planetary formation are still uncertain. The main interest of the vortices is their ability to rapidly capture and trap the solid particles; indeed, the large clumps formed in the vortex […]
"Constraining the formation and evolution of the largest main belt asteroids" Abstract Asteroids in our Solar System exhibit a wide variety of sizes, shapes, compositions, and orbital properties and provide powerful constraints for planetary system formation models. However, little is known regarding their densities and internal structure although these are fundamental properties that derive from […]
Title: Early Planet Formation: Exploration Goals for NASA's Lucy and Psyche Mission Speaker: Prof. Richard Binzel (MIT) Abstract: Two NASA spacecraft missions, Lucy and Psyche, will explore distant asteroids in our solar system that provide a window to the earliest era of planet formation. Lucy, launched in 2021 is en route to explore a group […]
Pavan VYNATHEYA (Max Planck Institut für Astrophysik, MPA, Garching): "Gravitational waves from quadruple stars - quadruple the fun (?)" The cafe-club will take place at 11:00 on zoom AMU virtual room. You can find the schedule of upcoming café-clubs and the video of old ones on the Cafe Club wiki Take care, Carlo, Mathilde, Meriam […]
Loïc Barbot PhD student will present his work on astronomical navigation. Here is the abstract of the presentation : Astronomical navigation is still studied in merchant or naval academies as a method to fix the position of a ship. Considered as an emergency technic, it is implemented by an observer measuring with the sextant the […]
Dear all, The Galaxy Evolution Circle will restart in a different format. Every two weeks, we will pick-up a particular subject. The idea will be to create a round table where we will discuss the following points: – An small introduction. – Classic and recent articles. – Active (LAM) people working on the subject. – Instruments. – On-going and future projects. – Perspective. For our second G.E Circle (28/Oct./15h at Mistral room) we propose to discuss Star formation in The WM and nearby galaxies. The idea is to maintain the discussion lively and informal. We look forward to have your presence in person.
Laurie Paillier research engineer at ONERA will present her work about optical links from ground to space. Here is an abstract of her presentation : Both the increasing imaging resolution of earth observation satellites and the advent of a space based globalized internet are currently urging for very high data rate transmissions between space and […]
Tobias BROWN (Herzberg Astronomy & Astrophysics Research Centre, Victoria, Canada), who will talk about "How environmental processes regulate the gas-star formation cycle in Virgo Cluster galaxies". The cafe-club will take place EXCEPTIONALLY at 4:00 pm on usual AMU virtual room and will be broadcast in the Library at LAM; you are invited to meet there 10 min before the talk bringing your […]
Laboratory visit by the HCERES committee: presentations, visits, meetings as announced by email.
Title: Machine Learning as a connection to bridge astrophysics with real world problems Abstract: In the last few years my career has spanned predicting epidemics in Burkina Faso, detecting Russian missiles with Mobile Phones, measuring the expansion rate of the Universe with gravitational lensing and detecting Dark Matter with Galaxy Clusters. It seems that they […]
Within the MITI CNES/CNRS BOBAFET context, a three days workshop is held in LAM by Laure Ciesla including GECO members (O. Ilbert, V. Buat, R. Gavazzi), IAP and CEA researchers as well as guests from Cambridge. The workshop is dedicated to the modelling of star formation histories of galaxies from multi-wavelength observations and includes discussions […]
"Modelling the populations of low-mass planets: transition between super-Earths and mini-Neptunes" Zoom link: https://univ-amu-fr.zoom.us/j/88020777410?pwd=WlNQL1VyYWxOQjFaQ1pnU0I3SUpPdz09 Abstract Low-mass exoplanets are showing a diversity in their densities and irradiation conditions, ranging from highly irradiated planets to temperate worlds. To estimate their composition, we have developed an interior structure model that includes self-consistently an atmosphere in radiative-convective equilibrium. The […]
