1. 1. The visibility of stellar transients in the Galactic Centre

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

   Author : Jonathan Ström; [2024]
   Keywords : Physics and Astronomy;

   Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE
