SUMMARY:NRF|SAAO Cape Town Open Night
DESCRIPTION:Join us for Open Nights at the South African Astronomical Observatory (NRF/SAAO) in Cape Town\, held on the second and fourth Saturday of every month. \nEach evening begins with an engaging presentation on astronomy or a related field of science\, followed by a guided tour of the Observatory’s rich history—including our library\, museum\, and the historic 120-year-old McClean Telescope. \nWeather permitting\, guests will have the opportunity to enjoy stargazing through the Observatory’s outreach telescopes. \n\n\n\nGates open at 7:30 PM.\nFree entry for children aged 6 and under.\n\n\n\nPlease email cptbookings@saao.ac.za or call +27 21 447 0025 if you have any queries regarding bookings. \n\n\n\n\nSpeaker: Dr Kelebogile Gasealahwe \n \nBio: Dr Kelebogile Gasealahwe is a SARAO postdoctoral research fellow at the University of Cape Town. She is affiliated with both the SAAO and SARAO\, and is a fellow in the High Energy Physics\, Cosmology & Astrophysics Theory (HEPCAT) group. Her research focus is on X-ray binaries\, primarily studying neutron star X-ray binaries from a multi-wavelength perspective. She is a member of South Africa’s Astronomy Community Task Team (ACTT) and a member of the Golden Key International Honours Society. Dr Gasealahwe is a recipient of the South African Women in Science Awards DSI – Esther Mahlangu Doctoral fellowships (2024) and a keynote motivational speaker. \nAbstract: Astronomical objects often remain singular\, unaffected by other objects. Sometimes\, objects are paired and may even interact with each other; these are known as binary systems. X-ray binaries are systems with either a black hole or neutron star as the primary object\, and a companion star as the secondary object. During intense interactions\, X-ray explosions occur\, one of the brightest X-ray sources in the night sky. In this talk\, we will uncover the nature of X-ray binaries and how they are observed. I will present results from the youngest known X-ray binary\, Circinus X-1\, the Africa nebula. Moreover\, discuss how it may tie together what we know about X-ray binaries with either black hole or neutron star primary objects. \n
