Description
This event is the annual in-person meeting (Caen, 10-11 July, 2025) of the MAC project. This theoretical collaboration builds on the previous MAC (2017-2019) and NewMAC (2020-2022) projects. The details and materials about the first in-person meeting of the renewed IN2P3 Master Project MAC (2023-2026) can be found on the Indico-IN2P3 webpage of the 2024 MAC meeting, which took place in Orsay (indico.in2p3.fr/event/32939).
Registration will be open to the members of the project and invited speakers.
The IN2P3 Master Project "Modélisation des Astres Compacts" (MAC 2023-2026) aims to deliver quantitative predictions of key parameters governing observable signals from neutron stars, constrained by uncertainties in underlying microphysics.
One of the main goals of the current MAC project is to refine nuclear physics-based models to better understand compact stars and their multi-messenger signals. The focus is on neutron stars, hybrid stars, quark matter, and high-energy phenomena such as core collapse and compact star mergers. Emphasis is placed on how microphysics-informed modelling of nuclear matter links experimental nuclear and hadron physics with multi-messenger observations. During the years, the three MAC projects mainly focused on:
(i) Gravitational wave emission from neutron star binaries or isolated neutron stars (e.g., oscillation modes) where dominant uncertainties stem from the dense-matter equation of state (EoS) and potential phase transitions.
(ii) Core-collapse supernova dynamics and neutrino spectra, modeled with consistent EoS and nuclear statistical equilibrium.
(iii) Neutron star cooling and crust crystallization, influenced by EoS and surface properties of neutron-rich nuclei.
A feature of the current MAC (2023-2026) project is that it aims to integrate experimental nuclear physics and astrophysical modelling and to foster proposals for targeted measurements. More information and material can also be found on the webpages of the 2024 MAC meeting, as well as the previous 2021 MAC meeting and 2020 MAC meeting, or at the CNRS webpage dedicated to the first edition of the MAC Master Project (which, while not fully up to date as it refers to an earlier edition of the project, still contains relevant content: mac.in2p3.fr/).

How to reach LPC: from the Caen train station, take the tram line T2 (red) to the last station (Campus 2). LPC is just a 1-minute walk from the tram stop. The local tram line is called Twisto: you can check the timetable and itineraries at https://www.twisto.fr/en. Alternatively, Caen has a wonderful airport that is served by a public bus line: https://caen.aeroport.fr/.
Practical info: There are no registration fees for this meeting, and no lunches are provided. Participants should book a hotel if necessary. Hotels close to LPC Caen are: Hôtel Mercure Caen Côte de Nacre and Hôtel Carline. More hotels are listed on the webpage of the GANIL guesthouse, which may also be a solution (please follow the instructions on the GANIL guesthouse webpage and put A. Fantina in CC when submitting your request). The city centre of Caen is charming and offers plenty of options; we recommend booking a hotel there, as tram line T2 runs directly through the area. For those interested, the Tour de France will pass through Caen on July 9 (see also letour.fr/fr/etape-5), which may cause some disruption to public transport services that day.
