ALMA's sharpest view of IRAS 08544-4431: Unveiling the dust distribution asymmetries in the circumbinary disk

Maksym Mohorian, Devika Kamath, Elizabeth Cappellazzo +10

The interactions between post-asymptotic giant branch (post-AGB) binaries and their circumbinary disks play a central role in shaping the evolution of these systems. Circumbinary d…

Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS

Y. Carteret, V. Bourrier, L. Parc +57

The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…

Bayesian classification of astronomical spectra with class uncertainties

Simon Barton, Martin Sahlén, Andreas Korn +1

Context: We developed a probabilistic machine learning method with the aim of performing the O(10)-way classification of low- and high-resolution spectra of stellar and extragalact…

Local constraints on alcohol--thioalcohol analogs in G35.2N

Xuefang Xu, Shanghuo Li, Qian Gou +6

The chemistry of sulfur-bearing complex organic molecules in dense star-forming environments remains uncertain, partly because the dominant sulfur reservoirs in dense gas and ices…

Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk

Wu Yaqian, Xiang Maosheng, Zhao Gang +4

The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…
