Dr. Khargharia explaining X-Ray Binaries
In the March 2013 meeting, Dr Juthika Khargharia presented on the techniques to measure the mass of black holes in x-ray binaries developed by Dr. Khargharia. These results have been accepted by the Astronomical Journal. This talk covered a lot of ground and it generated many questions. This was quite a popular meeting.
First Dr. Khargharia described the basics of X-ray binaries. In order to do this a black hole must have a companion star. Both objects orbit each other. She described that you had to use the companion star to measure the mass of the black hole.
This led the discussion into the processes to measure XTE J1118+480, which was her thesis for her doctorate. She showed the data that was obtained. She also went through some of the procedure to obtain time on the telescopes used.
At the end of the talk, she went through the challenges of infrared astronomy, the process used to calculate the black hole mass and her
conclusions from her research. A copy of her presentation can be obtained below.
