SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor

Zhen Guo, Calum Morris, Vitor Fermiano +37

Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…

Unresolved triples in the open cluster NGC 2437 (M 46) confirmed by the KMOS VVVX-GalCen Spectroscopic Survey

D. Minniti, T. Palma, C. O. Obasi +31

Recent optical and near-IR photometric databases like Gaia data release 3 (DR3) and the VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey allow the exploration of…

Unresolved triple systems in the aged open cluster Trumpler 19: Discovery, confirmation, and implications

D. Minniti, R. K. Saito, V. D. Ivanov +31

It is difficult to identify unresolved triple and higher-order systems beyond the solar vicinity. Star clusters yield controlled environments with known physical parameters, provid…

Photoionization of the Composite Nebula Surrounding NGC 5408 X-1: Implications for Beamed Emission

Jing Guo, Hua Feng, Roberto Soria +4

NGC 5408 X-1 is one of the best studied ultraluminous X-ray sources (ULXs) and is surrounded by a photoionized nebula. Previous optical spectroscopy established the presence of str…

Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds

N. Castro Segura, K. Solomons, J. M. Corral-Santana +22

Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…

Disc Winds From Accreting Systems in the 2040s

Noel Castro Segura, Virginia Cúneo, Francesco Tombesi +9

What does the temporal evolution of disc winds tell us about accreting systems and the accretion process? Studies of accretion-disc outflows across all mass scales, including accre…
