Percent excess absorption from TOI-2134 b as a function of time and wavelength (stellar rest frame). Credit: Zhang et al., 2023. Percent excess absorption from TOI-2134 b as a function of time and ...
Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...
