Ares Osborn

I'm Ares (they/them), a PhD student in the Astronomy and Astrophysics group at the University of Warwick under the supervision of Dr Dave Armstrong (2019-2023).
I also completed my MSc by Research (2018-19) in the department under the supervision of Dr Daniel Bayliss.

Research Interests

My PhD project will begin by characterising the TESS Object of Interest TOI-431, a system thought to contain 2 planets that has been recently looked at with HARPS. This should hopefully lead to a discovery paper. The long term goal of the project is to use TESS data to study the overall planet population, particularly to study planet occurrence rate as a function of density and hence composition.

My Master's looked at the planet-metallicity correlation - that is, the correlation between a star's metal content and the probability it hosts a (giant) planet. I looked at this correlation specifically for hot Jupiters, a subset of giant planets that are Jupiter-sized, but with orbits around their host stars of only a matter of days. An increasing number of these have been found by transiting exoplanet surveys (for example: WASP, KELT, HAT and HATS), from which I compiled my sample. My findings were accepted for publication by MNRAS in Nov 2019.
