The MPIA call for summer interns is now live! This is a great opportunity for bachelors & masters students from anywhere in the world to come an complete a three month, fully funded research project in beautiful Heidelberg. Check it out here: www.mpia.de/en/careers/i...

⭐️✨🔭Please help us get the message out about the 7th annual international ASPIRE program at @api.uva.nl. This summer 2026 school provides astronomy research experience for talented MSc students from countries where opportunities to move into a PhD program are limited. Applications are due 17 Dec! ⭐️✨🔭

🔭🧪🎢 PhD Project focus: Understanding protoplanetary disc evolution We're advertising this project with Prof Richard Alexander, making simulations of accretion of planet-forming discs onto their star. For details of all our PhD projects look here: le.ac.uk/study/resear... 🔭🧪🎢

New paper, led by @physicsuol.bsky.social PhD student @simintong.bsky.social. Simin looked at the rings we see in planet-forming discs, and combined new models with multi-wavelength ALMA observations to understand the underlying physical properties of the dust and gas. 🔭 arxiv.org/abs/2509.24818

@simintong.bsky.social is giving a talk (remotely) on our new paper (👇🏻) at the "Pebbles in Planet Formation" conference in Tokyo this week. [Simin's talk is on Thursday morning; for those attending online, it's overnight Wed/Thu in Europe, or Wed evening in the US.] 🔭 indico2.riken.jp/event/5012/

New paper, by Leicester PhD student @simintong.bsky.social. Simin presents a new set of models which show that compact protoplanetary discs are a natural consequence of so-called ``dead zones'': regions where disc turbulence is low. 🔭 arxiv.org/abs/2502.04452
