Amber Sedgley

I am a first year PhD student in the Astronomy and Astrophysics group at the University of Warwick, supervised by Peter Wheatley and Daniel Bayliss, and working closely with Sam Gill in the NGTS Monotransits working group.

My Research:

My project focuses on detecting, confirming, and characterising long-period transiting exoplanets, particularly those that display one or two transits in TESS observations. I analyse both TESS and NGTS photometric data, as well as organise and manage photometric follow up with NGTS (and other facilities where appropriate), and arrange spectroscopic reconnaissance and follow-up for confirmed or interesting candidates. The overarching goal is to discover planets with long orbital periods, bridging the gap between the well-studied hot Jupiters (favoured by detection bias) and Solar System giants. These long-period planets can provide insights into planet formation in the Solar System and beyond.

Teaching:

I am a lab demonstrator in the second year undergraduate physics labs assisting with a time series photometry experiment to measure variability in binary star systems. PX283-30Link opens in a new window
