Postdoc astrophysicist @ University of Southern Queensland searching for exoplanets. Using MINERVA-Australis telescope array to confirm TESS transiting planets.

Just had my first dose of the Pfizer vaccine for Covid-19! Had to wait 1.5 hours at the walk-in clinic but got it done!

I'm excited to announce the discovery of an ultra-hot Jupiter, TOI-1431b/MASCARA-5b. This massive planet orbits its host star every 2.65 days and has the second hottest nightside temperature ever measured of ~2560K!

@JontiHorner @austronomer @LeaksPh This was just mentioned in the Minerva North meeting lol

[University of Southern Queensland @unisqaus]

💫 @usqedu astrophysicists @astrobrett1 and @JontiHorner talk to @TomHartley_7 about their latest #exoplanet discovery.

For all the deep space details 📺 tune into @7NewsBrisbane tonight.

@DuaneHamacher @arxiv @StargazerFred @darkskyalliance @IDADarkSky @darkskyaus @SpaceAusDotCom @AusSpaceAgency @AboriginalAstro @AstroSocAus @CosmosMagazine @IAU_org While I agree that light pollution is problematic for both astronomy and indigenous cultures, calling it cultural genocide is pretty extreme rhetoric and might offend some groups.

A little late to the party (rarely use Twitter) but I'm excited to announce the #exoplanet discovery that I led, TOI-257b, a warm sub-Saturn. Transits initially detected by @NASA_TESS & RV measurements from our @minervasouth facility confirmed the planet. https://t.co/Kt9VHoDDLv

@AstroThayne @TMTHawaii This is excellent to hear. I definitely expected to hear about anti-TMT protests. I'm glad astronomers and non-astronomers alike have come out in support the TMT and have made their voices heard!

@spacejayk I never realized that here in Australia the banks don't have drive-thrus. I'm guessing I didn't notice this since I never really used them in the states. I can see them being useful for parents with young kids but I think it has more to do with convenience & driving culture.

What do astronomers do in Boston? They go to @fenwaypark of course! 🧦🌶️ @johannateske @Astrobrett1 @austronomer #MLB

@Tergenev @minervasouth Yes I am.

Prof. Rob Wittenmyer giving his talk on Minerva-Australis telescope array (@minervasouth) and the TESS RV follow-up and exciting science we are doing with this facility. Go Minerva! #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

Dr. Belinda Nicholson talked about the Minerva-Australis efforts to follow-up single transit planet candidates from TESS. #TESScon #MinervaAustralis #usqastronomy

Conclusion, low occurrence rate of inner companions suggest HJs are formed through migration. #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

Why study inner companions to hot Jupiters? Inner companions to HJs can tell us the frequency of HJs that can be formed in situ as opposed to forming beyond the ice line and migrating in. #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

Very interesting talk by George Zhou on the occurrence rates of hot Jupiters around early-type stars. One might expect these planets to be more common around massive stars. However, George concludes hot Jupiters do not appear to be more frequent around early-type stars. #TESScon

Bedding points out the built-in HR Diagram in the Kresge auditorium at #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

This plot has all the information that you could possibly want on planet bulk compositions. #TESScon

The Fulton gap in the distribution of small planet radii. #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

So far 993 planet candidates have been found so far! 24 planets have been confirmed and published. #TESScon

[Brett Addison 🏳️‍🌈 @Astrobrett1]

Yes please! 3x the science! #TESScon
