Bouncing against the Yellow Void — exploring the outbursts of ρ Cas from visual observations Grigoris Maravelias and Michaela Kraus Massive stars are rare but of paramount importance for their immediate environment and their host galaxies. They lose mass from their birth through strong stellar winds up to their spectacular …
Recently we had a few changes in our group: Frank moved to the Institute of Astronomy, KU Leuven, while Gonzalo Muñoz Sanchez joined the team as a new PhD student.
A new automated tool for the spectral classification of OB stars E. Kyritsis, G. Maravelias, A. Zezas, P. Bonfini, K. Kovlakas, P. Reig (abridged) We develop a tool for the automated spectral classification of OB stars according to their sub-types. We use the regular Random Forest (RF) algorithm, the Probabilistic …
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 …

Then you can take a look at our talks from the 15th Hellenic Astronomical Conference that became recently available online.
Over the last year and half, the ASSESS group has obviously been affected by the pandemic situation and the restrictions. Although we haven’t met in person, we keep on meeting on a weekly basis, as we all continue working from home. Unfortunately, this has vanished the opportunities to take any …
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 massive stars in nearby galaxies in the framework of the ERC consolidator grant titled “Episodic Mass Loss in Massive Stars: Key to Understanding 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”, …
