New Paper Day!! 🥳 Here we explore the first order influence of differential rotation on the Sun's angular momentum-loss rate using a series of PFSS models that span Solar Cycle 24! 🚨arxiv.org/abs/2302.12700🚨 (1/7)

The deadline to apply to be on the committee is April 7th! Please email us ([email protected]) if you're interested :)

Happy Pride Month from everyone at SGMA! Did you know that last month, American Astronomical Society (AAS) adopted a new resolution drafted by AAS_SGMA in support of LGBTQIA+ individuals in astronomers: aas.org/about/governan… (1/3)

Happy pride month everyone! Please join SGMA next Wednesday, June 14 at 4pm ET to discuss the importance of mentorship and community among LGBTQIA+ astronomers. You can register and find more details here: umd.zoom.us/meeting/regist…

#PrideMonth Please join the AAS Committee for Sexual-Orientation and Gender Minorities in Astronomy (SGMA) on Wednesday, 14 June, at 4:00 pm ET to discuss the importance of mentorship and community among LGBTQIA+ astronomers. ow.ly/Giaf50OGX8L

Nice paper by Yuxi(Lucy) Lu and collaborators on arXiv.org last night: "An abrupt change in the stellar spin-down law at the fully convective boundary". Now it's time for dynamo theorists to explain this convincing result! arxiv.org/abs/2306.09119

⭐️ Check out our paper now on the arXiv! ⭐️

✅ Thesis defended! A big thank you to all the people who helped me through and participated in my PhD journey 🙏

Extremely low-mass stars, unlike the Sun, lack radiative cores. This could affect their magnetic dynamos. Yuxi(Lucy) Lu et al. reveal they can have 30% stronger magnetic fields than Sun-like stars, implying fundamental differences in their magnetic structures. nature.com/articles/s4155…

Grateful to Center for Astrophysics | Harvard & Smithsonian for featuring our recent discovery of the Magellanic Stellar Stream, along with this beautiful artwork by Melissa Weiss cfa.harvard.edu/news/distant-s…

"Gaia DR3 data consistent with a short bar connected to a spiral arm" -- arxiv.org/abs/2312.03854 led by Ethan Vislosky (skhoperskov, Marie Martig, Tobias Buck, Matthias Steinmetz, T. Hilmi, Bridget Ratcliffe, @JossBlandHawthorn, Alice Quillen, Roelof de Jong, AIP, University of Rochester)

Interested in Galactic dynamics? But also interested in element abundances? Check out our new paper (ui.adsabs.harvard.edu/abs/2023arXiv2…), where we use a generative model to measure the acceleration field, mass density, and amount of dark matter in the MW disc with element abundances. 🧵

Hello SGMA mailing list! Are you going to AAS#243 in New Orleans? We invite AAS#243 conference attendees to a walking tour of the French Quarter focusing on LGBTQIA+ persons of interest and the general history of New Orleans. Detail below:

PAPER DAY! You know the star (51 Peg), but what do you know about its space weather environment? We derive a magnetic map from LBTObs spectropolarimetry and stellar properties from NASA_TESS asteroseismology. 👉51 Peg shows weakened magnetic braking! arxiv.org/abs/2401.01944

Stellar mergers or truly young? We have found a few intermediate-age stars in the Gaia-Enceladus/Sausage system (thought to be ancient). They appear to be truly young. If so, how did they get there? If not, why do they look young? ui.adsabs.harvard.edu/abs/2024arXiv2…

Now accepting applications to join the SGMA committee for a 3-year term starting in June 2024. This year, we expect to have at least 3 openings. - Deadline: March 31th, 2024 at 11:59 PM EDT - To apply, fill out the google form in the thread and answer the 4 questions!
