Evidence for a cyclotron absorption line and spectral transition in EXO 2030+375 during 2021 giant outburst
Wen Yang, Wei Wang, Prahlad R. Epili
Based on HXMT observations of EXO 2030+375 during its 2021 giant outburst, we report the analysis of pulse variations and the broadband X-ray spectrum, and find the presence of a p…
