Transiting Hot Jupiter and a Cold Massive Giant Planet Found by HATSouth Around a Sun-like Star
15 November 2018 - Co-author on another HATSouth planet discovery paper. This paper reports on the discovery of HATS-59b,c: A Transiting Hot Jupiter and a Cold Massive Giant Planet around a Sun-like Star. The papers can be found here.
Stellar Obliquities and Planetary Alignments (SOPA) Paper Published
01 November 2018 - Paper published on a project I started on measuring spin-orbit angles of planetary systems. Included in the paper are spin-orbit alignment measurements of three Jovian planets (WASP-72b, WASP-100b, and WASP-109b), two of which are highly misaligned (WASP-100b and WASP-109b)! The papers can be found here.
First Hot Jupiter Discovered by TESS, HD 202772Ab!
15 October 2018 - Co-author on paper with the first confirmation of a hot Jupiter discovered by TESS known as HD 202772Ab! The papers can be found here.

13 August 2018 - I have just started a postdoctoral Research Fellow in Astrophysics position at the University of Southern Queensland to find and characterise new exoplanets using the Minerva-Australis Telescope array with Prof. Rob Wittenymer.
Paper on Spin-orbit Alignments for Three Transiting Hot Jupiters Submitted Soon!
24 January 2018 - I will be submitting a paper in the next couple weeks on the spin-orbit angles of three Jovian planets, two of which are highly misaligned! Keep an eye out for it.
Papers on Relocating the Kepler-9b Transit & Measuring the Spin–Orbit Angle for Kepler-9

Awarded 2 Nights on Magellan MagAO to Continue Stellar Companion Survey
27 September 2014 - Graeme Salter, Brett Addison, Chris Tinney, and Laird Close have been awarded 2 nights on the Magellan Telescope using the MagAO adaptive optics system in Chile for 'Determining the Origin of Spin-Orbit Misaligned Hot Jupiter Systems' coming up in November. Our team will continue the search for stellar companions around Hot-Jupiter systems to determine if they are the primary cause of the observed spin-orbit misalignments.
