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...

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!!

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!

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... 🔭 🧪

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.

How low the University of Michigan has fallen since Grutter v Bollinger (2003). www.chronicle.com/article/were...

[Former University of Michigan and Columbia University President Lee] Bollinger: We’re in the midst of an authoritarian takeover of the U.S. government. It’s been coming and coming, and not everybody is prepared to read it that way. The characters regarded as people to emulate, like Orbán and Putin and so on, all indicate that the strategy is to create an illiberal democracy or an authoritarian democracy or a strongman democracy. That’s what we’re experiencing. Our problem in part is a failure of imagination. We cannot get ourselves to see how this is going to unfold in its most frightening versions. You neutralize the branches of government; you neutralize the media; you neutralize universities, and you’re on your way.

We’re beginning to see the effects on universities. It’s very, very frightening.
