Dr. Jack Hughes

October 9, 2018

Peyton Hall

7:30 p.m.

The October AAAP meeting is on the 9th at 7:30PM in Peyton Hall on the Princeton University campus. The talk is on the “Stellar Nucleosynthesis” by Dr. Jack Hughes, Rutgers University.

Dr. Hughes will focus on the basics of stellar nucleosynthesis and will finish up with more recent research topics. Dr. Hughes will discuss hydrogen-burning on the main sequence, helium burning and hydrogen shell burning on the red giant branch, and then, in stars of >8 solar masses, and later stages of burning ending up with iron. Also, briefly mentioned is Big Bang nucleosynthesis since it sets the stage for the rest of the story. Dr. Hughes, will also briefly cover supernova explosions, which are (mostly) how the metals produced in stars get into the interstellar medium and the extra boost they give to nucleosynthesis. Time permitting, Dr. Hughes will talk about the role of high energy astrophysics in the continuing evolution of our understanding of the origin of the chemical elements in the universe, such as studies of Fe-group elements in type Ia supernovae* (read "type one-a") and the role of recent multi-messenger observations of neutron star mergers.

The talk looks very interesting and will cover a lot of ground!!

Prior to the meeting there will be a meet-the-speaker dinner at 6PM at Winberie’s in Palmer Square. If you are interested in attending please contact no later than Noon on October 9.

Parking is available opposite Peyton Hall.

We’re looking forward to seeing you at the meeting!

* Ia supernova is a supernova that occurs in binary systems where one of the stars is a white dwarf.
