X-shooter survey Across Regions and Ages to probe Disk Evolution (ARADE): Accretion properties in Orion A and their relation with disk masses
Lara Piscarreta, Giacomo Beccari, Carlo Manara +10
We present a homogeneous VLT/X-Shooter study of accretion in young stellar objects spanning the entire Orion A complex. Our sample includes 91 pre-main-sequence stars hosting a pro…
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…
WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +52
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…
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
K 1-6 has long been classified as a planetary nebula (PN) hosting a binary central star, yet it has remained poorly studied due to its faintness. The central star exhibits pronounc…
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…
Progress on FORS-Up: the first instrument using ELT technologies
H. M. J. Boffin, V. Baldini, S. Bertocco +21
ESO is in the process of upgrading one of the two FORS (FOcal Reducer/low dispersion Spectrograph) instruments - a multi-mode (imaging, polarimetry, long-slit, and multi-object spe…
Probing the Local Planetary Nebula Luminosity Function with Gaia
N. Chornay, N. A. Walton, D. Jones +1
The Planetary Nebula Luminosity Function (PNLF) remains an important extragalactic distance indicator despite a still limited understanding of its most important feature - the brig…
Towards a more complete sample of binary central stars of planetary nebulae with Gaia
N. Chornay, N. A. Walton, D. Jones +3
Context: Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However only a few percent of PNe in the Milky Way are known t…
The blue straggler population of the open clusters Trumpler 5, Trumpler 20, and NGC 2477
M. J Rain, G. Carraro, J. Ahumada +3
We present a study, based on Gaia DR2, of the population of blue straggler stars (BSS) in the open clusters Trumpler 5, Trumpler 20, and NGC 2477. All candidates were selected acco…
A study of the blue straggler population of the old open cluster Collinder 261
M. J. Rain, G. Carraro, J. A. Ahumada +4
Blue Stragglers are stars located in an unexpected region of the color-magnitude diagram of a stellar population, as they appear bluer and more luminous than the stars in the turno…
Opening PANDORA's box: APEX observations of CO in PNe
L. Guzman-Ramirez, A. I. Gomez-Ruiz, H. M. J. Boffin +5
Context. Observations of molecular gas have played a key role in developing the current understanding of the late stages of stellar evolution. Aims. The survey Planetary nebulae AN…
Close binary central stars and the abundance discrepancy - new extreme objects
R. Wesson, D. Jones, J. García-Rojas +2
Recent work (Corradi et al. 2015, Jones et al. 2016) has shown that the phenomenon of extreme abundance discrepancies, where recombination line abundances exceed collisionally exci…
Dissecting a SN impostor's circumstellar medium: MUSEing about the SHAPE of eta Car's outer ejecta
A. Mehner, W. Steffen, J. H. Groh +10
Aims. The structural inhomogeneities and kinematics of massive star nebulae are tracers of their mass-loss history. We conduct a three-dimensional morpho-kinematic analysis of the…
Ecology of Blue Straggler Stars
H. M. J. Boffin, G. Carraro, G. Beccari
The existence of blue straggler stars (BSS), which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution, as such star…
Numerical simulation of accretion discs in close binary systems and discovery of spiral shocks
Takuya Matsuda, Makoto Makita, Hidekazu Fujiwara +4
The history of hydrodynamic numerical simulations for accretion disks in close binary systems is reviewed, in which emphasis is placed, in particular, on the facts that spiral shoc…
