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…

Chlorine abundances in star-forming regions of the local Universe
M. Orte-GarcÃa, C. Esteban, J. E. Méndez-Delgado +4
Aims. We study the behaviour of Cl abundance and its ratios with respect to O, S and Ar abundances in a sample of more than 200 spectra of Galactic and extragalactic H ii regions a…
