DOI: 10.1007/s11182-019-01666-3
Abstract: Line profiles of the krypton spectra emitted by the plasma of current sheets are simulated. Current sheets are formed under the impact of magnetic fields with singular X-lines. The spectral line profiles are calculated by… read more here.

DOI: 10.1016/j.asr.2021.07.011
Abstract: An inverse P-Cygni profile of H13CO+ (1 → 0) in G31.41+0.31 was recently observed, which indicates the presence of an infalling gas envelope. Also, an outflow tracer, SiO, was observed. Here, exclusive radiative transfer modelings… read more here.

DOI: 10.1051/0004-6361/202039437
Abstract: The study of the X-ray line profiles produced by massive colliding wind binaries is a powerful tool for the characterisation of the stellar winds. We built a self-consistent program for the computation of line profiles… read more here.

DOI: 10.1093/mnras/staa1767
Abstract: Photoevaporation driven by high energy radiation from the central star plays an important role in the evolution of protoplanetary discs. Photoevaporative winds have been unambiguously detected through blue-shifted emission lines, but their detailed properties remain… read more here.

DOI: 10.1093/mnras/stae1603
Abstract: Understanding the explosion mechanism and hydrodynamic evolution of core-collapse supernovae is a long-standing quest in astronomy. The asymmetries caused by the explosion are encoded into the line profiles which appear in the nebular phase of… read more here.

DOI: 10.1093/mnras/stae2099
Abstract: Observations of ionised Hα gas in high-redshift disc galaxies have ubiquitously found significant line broadening, σHα ∼ 10 − 100 km s−1. To understand whether this broadening reflects gas turbulence within the interstellar medium (ISM) of galactic… read more here.

DOI: 10.3389/fspas.2025.1585683
Abstract: Two techniques to quantify the energy of an atmospheric gas remotely are the emission scale height and linewidth spectroscopy at high spectral resolution. In the latter, temperature, or effective temperature in the case of a… read more here.
