Description

With its impressive wide-fast-deep capabilities, LSST is poised to revolutionise the field of optical transient astronomy, with orders of magnitude improvements in detection rates across many transient types. Additionally, these capabilities also allow LSST to detect rarer transients. With a surge of recent discoveries of lensed stars in Hubble and JWST imaging, we investigate whether the increase in magnification, of a bright star as it crosses a caustic, can be detected by LSST. In this talk, I will describe the methods involved in determining whether these caustic-crossing events can be detected by LSST. I will explore the challenges facing the detection and identification of these events and highlight some of the potential applications gained from their study.
