The ASSESS team is joining the IAUS 366 “On the Origin of Outflows in Evolved Stars”, organized virtually from Nov 1-5. Alceste will give an overview (Wednesday, Nov. 3, @12:20 UTC) of the ASSESS project followed by the advance we have achieved over the last years, as first results are …
The Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens invites applications for 1 PhD position on characterizing evolved, dusty massive stars in nearby galaxies. The aim of the project is to determine whether episodic mass loss is a dominant process in the …

The ASSESS team is joining the 15th Hellenic Astronomical Conference, organized biennially by the Hellenic Astronomical Society. This is one of the greatest opportunities to meet old friends but, unfortunately, this time we will not mange to meet in Patras. Instead, it’s going to be held virtually from 5 to …
The ASSESS team is joining the European Astronomical Society’s conference 2021. Although planned to meet in person in Leiden (28 June – 2 July, 2021), due to the ongoing pandemic the conference became a virtual one. Alceste has a plenary talk entitled “New developments and challenges in massive star evolution”, …
