NSAS Seminar Series - Prof Orsola de Marco

On the 3rd Tuesday of the month (February to November) at 7:30pm, we meet on zoom or at Regis Hall in the grounds of St Ignatius’ College, Riverview Street, Riverview (Lane Cove) which features a presentation from a Guest Lecturer. These presentations generally focus on the theoretical aspects of Cosmology, Astrophysics and Astrophotography and can include some of the most up-to-date research and scientific findings. We are fortunate to be able to obtain speakers from Australia’s top universities and scientific community – our past Guest Lecturers have included the likes of Dr Fred Watson and Nobel Prize winner Prof. Brian Schmidt.

Our speaker this month is Prof Orsola de Marco, Physics and Astronomy, Macquarie University.  The topic is Stars in Stars and Planets in Stars.

Abstract: I will be talking about recent research on the nature of stellar collisions, when a star finds itself to orbit inside another. Occasionally similar interactions also happen between stars and planets. All interactions generate a luminous signal which is now going to be detected systematically with the newly opened Rubin telescope.

The format of the evening consists of a welcome to Members, Guests and Visitors, a quick discussion on general business of NSAS, the presentation from our Guest Speaker and then members usually stay for pizza and have a chat with a cup of tea or coffee.

These meetings are an excellent opportunity to get to know fellow members.
