Description
We present an approach to improve the radial velocity precision of NIRSPEC data (spectral resolution R = λ/Δλ ≈ 22,000) by using a self-calibration approach. We demonstrate that the accuracy can be significantly improved by deconvolving the spectra and using the telluric lines as a long-term stable wavelength reference.

    Convection, rotation, and magnetic activity of solar-like stars from asteroseismology
    During the last decade, our understanding of stellar physics and evolution has undergone a tremendous revolution thanks to asteroseismology. Space missions such as CoRoT, Kepler, K2, and TESS have already been observing millions of stars providing high-precision photometric data. With these data, it is possible to study the convection of stars

    Tales of stellar & binary co-evolution, told by stellar oscillations
    Stellar binarity and stellar oscillations are mostly seen and studied as two separate phenomena. Sometimes, one process is even complicating the analysis of the other beyond the liking of one or the other research community. However, the complete picture painted by the physical constraints provided by the combination of both processes represents a
