About Event
In this edition of NASA’s Universe of Learning Science Briefings, we will learn how low-, intermediate-mass, and massive stars evolve in single- and binary-star configurations.
Dr. Roger Wesson will describe the evolution of low- to intermediate-mass stars, which are a major source of the lighter elements in the universe, and can also form some of its most beautiful and enigmatic objects: planetary nebulas.
Dr. Tea Temim will talk about the evolution of massive stars, their explosive deaths, and how they impact all aspects of astronomy.
Dr. Shazrene S. Mohamed will discuss binary star interactions and their role in producing complex, non-spherical outflows and powerful stellar explosions.
About the Series
The NASA’s Universe of Learning Science Briefings are professional learning telecons for the informal science education community, done in partnership with the NASA’s Museum & Informal Education Alliance, now found on NASA CONNECTS. These monthly thematic briefings highlight current NASA astrophysics explorations and discoveries from across the suite of NASA astrophysics missions. NASA scientists and engineers provide contemporary science results, and are able to respond to listener questions during the telecon. NASA-developed education and outreach resources, matched to the monthly theme, are included in every briefing.
In order to participate in the telecon and ask questions of the scientists, please join NASA’s Museum & Informal Education Alliance.
Facilitator & Presenters
-
Dr. Martha Irene Saladino is an Education & Outreach Scientist at the Space Telescope Science Institute, where she supports the outreach efforts of different NASA missions and projects, including the upcoming Nancy Grace Roman Space Telescope, and NASA’s Universe of Learning. Martha Irene obtained her Ph.D. in Astrophysics at Radboud University in the Netherlands, where she developed numerical simulations of evolved Sun-like double stars. Outside of work, Martha Irene enjoys running, reading, and digital illustration. -
Dr. Roger Wesson is a Research Associate at Cardiff University. He received his Ph.D. in astronomy from University College London (UCL) in 2004. After briefly leaving academia to work in the civil service, he returned to astronomy and to UCL for his first postdoctoral position in 2006. From 2011 to 2016, he worked for the European Southern Observatory in Chile, before returning to the UK once more. -
Dr. Tea Temim is a Research Astronomer at Princeton University. She previously worked on JWST’s Mid-Infrared Instrument at the Space Telescope Science Institute from 2016 to 2021, and was a research scientist and JWST postdoctoral fellow at NASA Goddard Space Flight Center from 2010 to 2016. She was a postdoctoral researcher and a predoctoral fellow at the Center for Astrophysics | Harvard & Smithsonian from 2007 to 2010, and obtained her PhD from the University of Minnesota in 2009. -
Dr. Shazrene S. Mohamed is a computational astrophysicist whose research focuses on simulations of evolved stars. She investigates how stars exchange mass, energy and momentum with each other and their surroundings, and the implications of these interactions for a wide range of phenomena, from the physics of bow shocks, bipolar and spiral outflows to powering symbiotic and X-ray binaries, nova and supernova explosions. A Rhodes Scholar, Shazrene holds a DPhil in astrophysics from the University of Oxford and an A.B. in astrophysics and mathematics from Harvard University. She spent two years as an Argelander Research Fellow at the University of Bonn in Germany before moving to Cape Town in South Africa where she held a joint position as an astronomer and associate professor at the South African Astronomical Observatory and the University of Cape Town. She recently moved to the University of Virginia in Charlottesville where she is an associate professor in the Department of Astronomy.
