Deadline has been extended to Oct 16!

Last week I had the opportunity to give a talk at the IAU Symposium for Massive Stars. ✨ I had a great time at the conference in Ensenada!!

Application for a mini-grant Sponsor your community building event with $100 from the AAS. We will particularly value creative ideas that build up communities that otherwise would not have a chance to meet or be supported.

🚨Call for Mini-Grant applications🚨
SGMA is looking to support 5 local, small scale events! Click on link for more information!

Hello everyone! We have joined BlueSky!!

We use BPASS to predict frequencies of ejected OB and OBe stars and binaries. We also predict companion frequencies and model distributions of primary & secondary masses & some orbital parameters. (Shoutout to @astro-jje.bsky.social !!)

Using RV measurements, we set constraints on companion masses and in some cases periods, eccentricities and inclinations. Our RV data suggest that OB binaries favor more circular orbits and OBe binaries are eccentric.

This is presenting an RV survey of field OB and OBe stars in the SMC Wing. We ID single and double-lined spectroscopic binaries and binary candidates. We also use TESS light curves to identify new eclipsing binary candidates!

New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS multi-object spectrograp...

🚨 Paper day!!! 🚨
Excited to announce that this project I’ve been working on these last few years has been published!

Promising hints of life found on distant planet K2-18b Scientists find new but tentative evidence that a faraway world orbiting another star may be home to life.

An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

Excited to announce that I’ll be giving my first conference talk at the IAUS 402! 🎉🎉🎉
