Stellar Obituaries

Stars have long lifespans that range from millions of years to hundreds of billions of years. But eventually all stars run out of fuel and die. When stars die, they can leave behind a white dwarf star, a neutron star, a black hole, or nothing but a bit of hot gas!
There have been a lot of discoveries in the field of stellar death in the last couple of years. In this talk I’ll introduce the main ideas behind white dwarf stars, neutron stars, black holes, and supernovae. Some of the recent observations of black holes and neutron stars include the first image of “the black hole’s shadow”, the measurements of colliding black holes and neutron stars, and observations of X-rays from binary systems containing a stellar corpse. I will provide a report on the most interesting stellar obituaries from the last couple of years, and explain what they tell us about how stars die, and how they change when they begin their new life as a black hole or neutron star.

From the Big-Bang to Life on Earth

Guest Speaker:

Dr. Laurie Rousseau-Nepton

From the Big-Bang to Life on Earth: A Story on the Birth of the Stars

 
The galaxy M33

The evolution of our Universe has been shaped by different eras since its early fast expansion, the Big-Bang. It has been a long way from a world with only light and elementary particles, to a world of galaxies, stars, atoms and molecules. In this presentation, we will travel through space and time and see how the stars have transformed the Universe, filling their surrounding with light, and allowing a wide variety of chemical elements to propagate in space. Billions of years of star-formation eventually led to the formation planetary system, just like ours, enabling life to emerge.

The Hubble Space Telescope was launched 28 years ago in 1990. After overcoming problems caused by a defective main mirror, Hubble has made discoveries that have revolutionized our view of the universe we live in. This talk will cover the history of HST based on a history book the speaker is writing for NASA.

Unravelling Star Formation

Orion in Infrared. Imaged by the Herschel Space Observatory

Stars form in the coldest, densest collections of interstellar gas, called molecular clouds.  Observations in the Milky Way and nearby galaxies show that molecular cloud mass is strongly related to the rate stars form. This relationship is rather surprising since it continues over a range of galaxy types and environments, suggesting that stars form through a common process. What controls that process, however, remains elusive. I will present recent observations of molecular clouds taken by new, state-of-the-art radio telescopes that are beginning to unravel the process of star formation. The quality of these observations is an enormous improvement from previous observations and has lead to an on-going revolution in our understanding of star formation.

The whole of the Moon: a journey to the center of our closest neighbor

The Lunar Interior

We know many things about our closest neighbor, the Moon.  Yet, its deepest part, close to the center, remains not well known.  In this presentation, I will give a brief overview of what we know about the Moon and its interior and how this information is obtained.  I will also show examples of the work that we do in my research group, where we use observations on the rotation of the Moon as a way to gather information about its deep interior.
