LineFit delivers more stable line-core intensity and Doppler velocity time series from complex multi-line solar spectra by combining adaptive windowing, asymmetric Voigt options, and split-core handling, outperforming standard fast estimators on synthetic benchmarks.
First obliquity measurement in an M dwarf binary shows alignment, with tentative evidence that aligned orbits around cool stars and wide separations also hold for brown dwarfs and binaries.
JWST spectroscopy of SIMP 0136 shows variability from three atmospheric regions linked to layers with forsterite clouds and water, using PCA, model combinations, and two new mapping methods.
Tentative CO detection from WASP-33b eclipse data alone with SPIRou validates stacking ingresses/egresses and shows Doppler eclipse mapping can constrain rotation with additional observations.
A spatial-variability proxy method applied to MURaM and MPS-ATLAS simulations of the Sun reveals stronger line-strength variations in neutral-element lines and larger central-wavelength shifts in singly-ionized lines.
The diagnostic separates granulation-sensitive and stable lines in late-G and K dwarfs, with FeI lines showing lower velocity sensitivity than FeII as effective temperature decreases, making solar line selections non-portable.
