Prof Jay Farihi, Professor of Astrophysics, Dept of Physics & Astronomy, Faculty of Maths & Physical Sciences. My main research activity is digging up evidence of terrestrial planetary systems at stellar corpses known as white dwarfs. One might not expect to find the surviving planetary systems around dead stars, but the universe is full of surprises.

I was set on being a Mounted Police Officer from a young age, but I knew it had to move

I assume they would disappear, but Jay, a very good evening to you.

1:24.9

Thank you for this. The plan is not only disappear, it's possible that they have it at a extended life.

1:30.9

First of all, where is it that you were looking to find WD-1054, a stroke 226?

2:00.9

I think people thought was quite a ridiculous idea, and I think that persists a little bit now.

2:06.9

But I will say this, we were not looking for things in the habitable zone.
