    • A Minimum Dilution Scenario for Supernovae and Consequences for Extremely Metal-Poor Stars 

      Magg, Mattis; Nordlander, Thomas; Glover, Simon C. O.; Hansen, Camilla J.; Ishigaki, Miho; Heger, Alexander; Klessen, Ralf S.; Kobayashi, Chiaki; Nomoto, Ken'ichi (2020-11-01)
      To date no metal-free stars have been identified by direct observations. The most common method of constraining their properties is searching the spectra of the most metal-poor stars for the chemical elements created in ...

    • Physical Processes in Star Formation 

      Girichidis, Philipp; Offner, Stella S. R.; Kritsuk, Alexei G.; Klessen, Ralf S.; Hennebelle, Patrick; Kruijssen, J. M. Diederik; Krause, Martin G. H.; Glover, Simon C. O.; Padovani, Marco (2020-06-02)
      Star formation is a complex multi-scale phenomenon that is of significant importance for astrophysics in general. Stars and star formation are key pillars in observational astronomy from local star forming regions in the ...

    • The Physics of Star Cluster Formation and Evolution 

      Krause, Martin G. H.; Offner, Stella S. R.; Charbonnel, Corinne; Gieles, Mark; Klessen, Ralf S.; Vazquez-Semadeni, Enrique; Ballesteros-Paredes, Javier; Girichidis, Philipp; Kruijssen, J. M. Diederik; Ward, Jacob L.; Zinnecker, Hans (2020-06-02)
      Star clusters form in dense, hierarchically collapsing gas clouds. Bulk kinetic energy is transformed to turbulence with stars forming from cores fed by filaments. In the most compact regions, stellar feedback is least ...

    • Self-consistent modelling of the Milky Way's Nuclear Stellar Disc 

      Sormani, Mattia C.; Sanders, Jason L.; Fritz, Tobias K.; Smith, Leigh C.; Gerhard, Ortwin; Schoedel, Rainer; Magorrian, John; Neumayer, Nadine; Nogueras-Lara, Francisco; Feldmeier-Krause, Anja; Mastrobuono-Battisti, Alessandra; Schultheis, Mathias; Shahzamanian, Banafsheh; Vasiliev, Eugene; Klessen, Ralf S.; Lucas, Philip; Minniti, Dante (2022-03-22)
      The Nuclear Stellar Disc (NSD) is a flattened high-density stellar structure that dominates the gravitational field of the Milky Way at Galactocentric radius $30\lesssim R\lesssim 300$ pc. We construct axisymmetric ...
