Edward Bryant

I am a PhD student (Oct 2018 - Sep 2022) in the Astronomy and Astrophysics group at the University of Warwick. My supervisor is Daniel Bayliss.

My research work is focused on the observations of transiting exoplanets, and I am currently working in two main areas:

1) Follow up of Bright Exoplanet candidate hosts with NGTS

I work within the Next Generation Transit Survey (NGTS) Bright Star working group to follow up the brightest exoplanet hosts (V < 10.5 mag) to look for potential transit timing variations (TTVs), to obtain robust estimates of the transit ephemeris for future observations, and to also find potential blends for candidate rejection. I lead the target selection, observation scheduling, reduction of the observations, and production of light curves for this working group. Through my work for this working group, I have contributed light curves to the discovery of multiple exoplanets. (See below for a full list).

A) Multi-Telescope Observations

A main part of my work in the Bright Stars Working group, I have been testing the use of multiple NGTS telescopes to simultaneously observe exoplanet transit events. This testing has shown that multiple simultaneous NGTS light curves combine beautifully to achieve photometric data of the same quality as the TESS space mission for bright stars (V < 10mag).

Within NGTS, I have also been involved in developing the quickfit routines for the pipeline which aid in candidate selection for follow-up.

2) Occurrence rates of Giant Planets orbiting M Dwarfs

The main current theory of planetary formation is core-accretion, which has been shown to inhibit the formation of the largest, Jupiter-sized planets around M dwarf stars. I am using data from the TESS mission to quantify the occurrence rates for these systems, and to determine the extent to which their existence is inhibited. This work will have important consequences for our models of planetary formation.
