No, the lions and tigers and bears have not rebranded! These are categories of exoplanets (planets around other stars). At first, we only knew about a small handful of exoplanets, but they were nothing like the planets from our solar system. As our methods improved, the discoveries kept piling on and now there are several thousand known exoplanets from many different detection techniques. Tonight, I’ll give a summary of exoplanet search techniques and what we know so far about these planets. I’ll also talk a little bit about my own research and share some experiences from studying some of the largest exoplanets using telescopes on Maunakea and Palomar.

Bio: Dr Henry Ngo is currently a Plaskett Postdoctoral Fellow working for the National Research Council of Canada at the Dominion Astrophysical Observatory. He was born in Mississauga, Ontario but grew up in Richmond, BC. He studied at UBC for his bachelors, Queen’s University in Kingston, ON for his Masters and just finished his PhD in Planetary Science at Caltech last summer. Henry and his family are happy to be back in BC and they are loving life on beautiful Vancouver Island!

SPEAKER: The Hunt for Black Holes in Globular Clusters

Posted by as Meetings

by Dr. Vincent Hénault-Brunet

Wednesday March 14th 2017 at 7:30 PM

Room A104, Bob Wright Centre

Globular clusters have long been used to test theories of stellar evolution, stellar dynamics, and galaxy formation. In recent years, these old clusters have emerged as fertile grounds to search for black holes and understand their formation. “Intermediate-mass” black holes have been proposed to lurk in their centres and could represent seeds from which super-massive black holes grow in the early universe. Dynamical formation of stellar-mass black hole binaries in the dense cores of globular clusters has also been suggested as a main formation channel for the sources of gravitational waves recently detected by the LIGO experiment. I will give an overview of the recent successes (and failures) of astronomers’ exciting hunt for black holes in globular clusters.

Bio: Vincent Hénault-Brunet recently joined NRC Herzberg as a Plaskett Fellow. He was born in Montreal, where he completed his BSc in physics from McGill and MSc in astrophysics from Université de Montréal. He then obtained his PhD from the Institute for Astronomy at the University of Edinburgh (UK), and was a research fellow at the University of Surrey (UK) and Radboud University (Netherlands) before moving to Victoria. His research focuses on stellar populations and globular clusters, in particular on the dynamics of stars in these systems.

President’s Message – March 2018

Posted by as President's Message

As the spring and summer approaches, planning is underway for our annual season of outreach events. The first event of the season is Astronomy Day on Saturday, April 21 at the Royal BC Museum. We will require volunteers to help with this event including people for the information table, people to do a show and tell with telescopes and their astrophotography, and some solar viewing as well if the skies cooperate. If you have not already been contacted and wish to help out, please contact Ken (outreach@victoria.rasc.ca) to put your name on the list as an outreach volunteer.

We will be holding another season of Star Parties at the Dominion Astrophysical Observatory on Saturday evenings. The first of these evenings will be on Astronomy Day. The season will continue until Saturday, September 1 for a total of twenty evenings. Planning is underway for some special evenings including Saturday, May 5 to coincide with the 100th anniversary of first light of the Plaskett Telescope that was on May 6, 1918. Again we will need people to be on hand to direct the visitors, provide views of the sky with telescopes, and other duties. We have a contact list of volunteers but if you are not on the list already and would like to be added please contact Chris (president@victoria.rasc.ca).

The annual general meeting of the Canadian Astronomical Society (CASCA) is taking place in Victoria this year. The conference title is A New Century for Canadian Astrophysics and it will be at the convention centre from May 22 to 26. Through a special arrangement with the organizing committee, members of RASC may register to attend. The options for RASC members are a one day rate or four day rate; the early bird rates are in effect until April 6. Complete details about the meeting, including a list of invited, centenary, and education and public outreach speakers, an outline of the graduate student workshop program, and special events, can be found on the CASCA 2018 website. One of the speakers, former RASC president R. Peter Broughton, is the author of new book about John Stanley Plaskett founder of the Dominion Astrophysical Observatory. Entitled Northern Star J.S. Plaskett, it is now available from the RASC store.
