The Bimodal Mass Ratio Distribution of the Hyades
Henri M. J. Boffin
The distribution of stellar mass ratios, q, in binary systems provides critical insights into the dynamical history and star-formation processes of open clusters. Here, I re-evalua…
K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system
Jaroslav Merc, David Jones, Ana Escorza +22
The study shows that nebula K 1‑6 is not a planetary nebula but interstellar gas photoionised by an evolved hot white dwarf, and that its central star is a hierarchical triple syst…
WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +53
The Wide-field Spectroscopic Telescope (WST) is a concept for a dedicated 12-m spectroscopic survey facility designed to address some of the most important questions in astrophysic…
The Wonderful World of Binary Stars
Andrea Barone, Henri M. J. Boffin, Beatrice Caccherano +6
During the 2026 ESO La Silla Observing school, about twenty students attended lectures and performed observations to learn various aspects of observational astronomy. The school, w…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
