A&A community survey on the future of scientific publishing: Credibility over speed, fairness over profit, human judgment over automation
João Alves, ArÅ«nas KuÄinskas, Charlotte Van Rooyen +7
(Abridged) Scientific publishing is undergoing major change, driven by a shift toward open access (OA), the rise of artificial intelligence (AI), and growing demands for transparen…
Gaia DR3 Variable White Dwarfs vetted by ZTF
Timour Jestin, Thinh Nguyen, Laurent Eyer +6
The publications of Gaia DR2 and DR3 have brought major improvements in stellar astrometry and photometry, particularly regarding the description of the white dwarf sequence. Notab…
Toward the time-domain spectroscopic study of the dynamic life of stars: from accretion to magnetic activity
Fatemeh Zahra Majidi, Amelia Bayo, Marc Audard +11
Stars and planets can be seen as the second fundamental building blocks of baryons in the universe (only second to the dust and gas in molecular clouds). Their formation involves d…
Exploring Young Stellar Variability with Gaia DR3 light curves
Chloé Mas, Julia Roquette, Marc Audard +5
Context: Photometric variability is a defining characteristic of young stellar objects (YSO), which can be traced back to a range of physical processes taking place at different st…
Linking Young Stellar Object Morphology to Evolutionary Stages with Self-Organizing Maps
David Hernandez, Odysseas Dionatos, Marc Audard +5
Studies in the past few decades have investigated young stellar object evolution based on their spectral energy distribution (SED). The SED is heavily influenced not only by evolut…
The NEMESIS Catalogue of Young Stellar Objects for the Orion Star Formation Complex. I. General description of data curation
J. Roquette, M. Audard, D. Hernandez +5
The past decade has seen a rise in the use of Machine Learning methods in the study of young stellar evolution. This trend has led to a growing need for a comprehensive database of…
