PUBLIC   LECTURE:

" WHEN STARS GO BANG ! "

"Live fast and die hard: the evolution and death of massive stars"

By Prof. Jose Groh, NASA SCIENTIST

8pm Monday October 14th. ALL WELCOME

 

ABOUT THE LECTURE

Stars more massive than 8 Suns end their lives in dramatic supernova explosions.

But before dying, these monster stars have tumultuous lives when they blow winds, suffer giant eruptions, and interact with companion stars.

In this talk, Prof. Jose Groh (TCD) will give an overview on the fast lives of the most massive stars in the Universe and how they evolve.

He will also discuss the roles of massive, monster stars as cosmic engines of the Universe.

We have just discovered that all the giant atoms in our bodies, essential to life, are NOT made in a supernova. So, where does your life come from? Come and find out, and bring everyone you know!

 

 


ABOUT THE SPEAKER

 

 

This is a lecture for the general public and our speaker will assume no prior knowledge of science, but here are his credentials to show why he is a world authority in this area:

Research Interests

  • Physical processes responsible for how stars evolve, die, and affect the Universe. My focus has been on: Progenitors of stellar explosions, such as Supernovae and Gamma-ray bursts
  • Evolution of massive stars across cosmic time ? Outflows and atmospheres of massive stars
  • First stars, their fates, and their impacts on the Universe I have been employing theoretical and observational approaches, combining multi-disciplinary techniques:
  • Multi-dimension radiative transfer and hydrodynamical modeling of stellar atmospheres and winds
  • Numerical models of stellar structure and evolution
  • Observations using optical interferometry, multi-wavelength spectroscopy and photometry

Current Position

Director of Astrophysics & Assistant Professor in Astrophysics, Trinity College Dublin.
