Knobs and dials of retrieving JWST transmission spectra. II. Impacts of pipeline-level differences on retrieval posteriors

Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3

Since the launch of JWST, observations of exoplanetary atmospheres have seen a revolution in data quality. Given that atmospheric parameter inferences depend heavily on the underly…

The magnetic and spin-down properties of slowly rotating fully convective M dwarfs

Victor See, Louis Amard, Stefano Bellotti +19

The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…

Evolving magnetic lives of Sun-like stars. I. Characterisation of the large-scale magnetic field with Zeeman-Doppler imaging

S. Bellotti, T. Lueftinger, S. Boro Saikia +6

Planets orbiting young, solar-type stars are embedded in a more energetic environment than that of the solar neighbourhood. They experience harsher conditions due to enhanced stell…
