It's paper day! 🎉 Happy to share our new paper published in @AandA_journal letters about the first detection of intermediate-mass stripped stars at low metallicity, a missing link towards forming Be X-ray binaries and double neutron star mergers. aanda.org/articles/aa/fu…

📢 The Small Magellanic Cloud is not one galaxy but two interacting systems! arxiv.org/abs/2312.07750

Want to know a bit more about Hengstberger symposium I organized last week at the IWH? Here is the @zah_hd news reporting about our cross-disciplinary meeting on stellar yields of massive stars: zah.uni-heidelberg.de/news/detail/he…

Magnetars are among the most bizarre and mysterious objects in the universe, and scientists are still unsure exactly how they form. But a unique helium-rich star that lies 3,000 light-years away may just have some answers, according to a study. cnn.it/3DYKRII

How hard is it to do science in a language that’s not your first language? We quantified the severity of #languagebarriers for non-native English speakers when reading/publishing papers and attending/presenting at international conferences. doi.org/10.1371/journa… 1/9

Superluminous supernovae, black hole mergers, and many more astrophysical puzzles are connected to massive stars at subsolar metallicities, which we investigate in the X-Shooting ULLYSES collaboration. Paper I has officially been published today: aanda.org/articles/aa/fu…

Hubble is looking at the Ext Star MLD95-LMC-1-546 with Cosmic Origins Spectrograph (COS/FUV) for Dr. Varsha Ramachandran. spacetelescopelive.org/2023-02-07T05:…

Interested in joining our hot star atmosphere group @zah_hd @UniHeidelberg? With you as a postdoc in our group, we would like to work towards a multi-dimensional treatment of hot star winds. Sounds great? Than take a look at the full job ad: wwwstaff.ari.uni-heidelberg.de/ansander/?cont…

1/ Webb has revealed a remarkable cosmic sight: at least 17 concentric dust rings emanating from a pair of stars. Located just over 5,000 light-years from Earth, the duo is collectively known as Wolf-Rayet 140. Read more: esawebb.org/images/WR140a/

How can we get more and better atomic data for #astrophysics? This is what we discuss at our #astroatom Atomic Data Workshop here at @UniHeidelberg/@zah_hd. Here is our first group picture of the in-person participants:

Setup almost complete for our Atomic Data Workshop at @UniHeidelberg supported by the @sfb881 and the @dfg_public. Reception starts in half an hour.

@HUBBLE_space tweets about our new paper on M33 X-7 😍. See the full paper in A&A doi.org/10.1051/0004-6…

Today on @arxiv : @varsharsw's comprehensive analysis of the BH X-ray binary M33 X-7 using phase-resolved @NASAHubble UV spectroscopy. Read about lower masses for the O-star and the BH (now only 38 Msun instead of previously assumed 70) and much more: arxiv.org/abs/2208.07773

In the afternoon session of #IAUS370, @varsharsw shows a lot of her recent and upcoming work on massive star winds at low metallicity. #IAUGA2022

Ready for another round of interesting talks in #IAUS370? ARI's massive star group @zah_hd looks forward to an interesting afternoon at #IAUGA2022 here in Busan.

1/ A team of international experts, renowned for debunking several black hole discoveries, have found a stellar-mass black hole in the Large Magellanic Cloud, a neighbour galaxy. 🔗 eso.org/public/news/es… Artist’s impression: @ESO /L. Calçada

The public are excited by the images, but astronomers are as excited by the spectra, like this one. I want to talk about why

HUBBLE vs JWST: Here's the difference. Welcome to a new era of astronomy.

Our #HST30 proposal Smoking guns in massive binary evolution: The hunt for Black Holes and Stripped Stars got accepted 😀. Getting #hubble time two years in a row as PI 🤩
