Investigating the electron temperature of [Ar IV] in planetary nebulae using the DESIRED database
J. GarcÃa-Rojas, E. Reyes-RodrÃguez, J. E. Méndez-Delgado +9
(Abridged) We investigate the behaviour of the electron temperature derived from [Ar IV] lines, Te([Ar IV]), in a sample of PNe to characterize the thermal structure of high-excita…

3DSTokesFlow: simulation-based inference for 3D Stokes profiles using flow matching
A. Asensio Ramos, K. E. Yang, M. J. Martinez Gonzalez +2
The standard interpretation of observed Stokes profiles to infer the physical conditions of the solar atmosphere is inherently an ill-defined problem due to observational noise and…

MUSE spectroscopy of the high abundance discrepancy planetary nebula NGC 6153
V. Gómez-Llanos, J. GarcÃa-Rojas, C. Morisset +5
(Abridged) The abundance discrepancy problem in planetary nebulae (PNe) has long puzzled astronomers. NGC6153, with its high Abundance Discrepancy Factor (ADF~10), provides an oppo…
