Limitations of the Ca II 8542 AA line for the determination of magnetic field oscillations


الملخص بالإنكليزية

Chromospheric umbral oscillations produce periodic brightenings in the core of some spectral lines, known as umbral flashes. They are also accompanied by fluctuations in velocity, temperature, and, according to several recent works, magnetic field. In this study, we aim to ascertain the accuracy of the magnetic field determined from
