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…
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…
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…
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…
A Deep Neural Network Approach to Compact Source Removal
M. Madarász, G. Marton, I. Gezer +5
Analysing extended emission in photometric observations of star-forming regions requires maps free from compact foreground, embedded, and background sources, which can interfere wi…
SED Modeling of Young Stellar Objects in the Orion Star Formation Complex
Ilknur Gezer, Gábor Marton, Julia Roquette +4
We performed a large-scale spectral energy distribution (SED) fitting analysis for young stellar objects (YSOs) in the Orion star formation complex (OSFC) to derive key physical pa…
