The Fate of Stars and the Universe:
From Black Holes to Dark Matter
Ata Sarajedini

PROGRAM DESCRIPTION: In this timely and important lecture series, Professor Sarajedini will illustrate how our knowledge of stars and their evolution is helping us to determine the nature and fate of the universe. We will trace the evolution of stars from their formation to adolescence, middle age, and death. Stellar death has one of three outcomes - white dwarfs, neutron stars, and black holes - each of which we will discuss. This will then lead us into how stars can be used to size-up the universe and its various properties. Along the way, Dr. Sarajedini will explain the differences between pulsars and quasars, white dwarfs and brown dwarfs, as well as black holes and dark matter. This series is geared to anyone with an interest in astronomy and learning about the universe.

1. Astronomy Basics: Description of the basic components and scale of the universe, planets, stars, and galaxies. Properties of the Sun and stars.
2. Stellar Evolution and Stars as Astrophysical Tools: How do stars form, evolve, and die? Discussion of white dwarfs, neutron stars, pulsars, and black holes. How are stars used to measure the size, age, and chemical composition of galaxies?
3. Properties of the Universe as Revealed by Stars: What is dark matter and how was it discovered? What does it tell us about the universe? How do we know that our universe is accelerating?
BIOGRAPHICAL INFORMATION: Dr. Ata Sarajedini is the Dean of the Charles E. Schmidt College of Science. Before coming to FAU in January of 2017, he served as Associate Dean for Natural Sciences and Mathematics as well as Associate Dean for Research in the College of Liberal Arts and Sciences at the University of Florida. Before that, he was Associate Chair and Acting Chair in the Department of Astronomy. After receiving his PhD in Astronomy at Yale in 1992, he spent seven years as a postdoctoral researcher and a Hubble Fellow at Kitt Peak National Observatory and San Francisco State University. Dr. Sarajedini spent two years at Wesleyan University in Middletown, CT as an Assistant Professor before moving to the University of Florida in 2001. His research is focused on resolved stellar populations in Local Group galaxies. These include field stars, open and globular clusters in the Milky Way, M31, M33, the Magellanic Clouds, and the numerous nearby dwarf galaxies.
