Further Evidence for the ~ 9 s Pulsation in LS 5039 from NuSTAR and ASCA
Kazuo Makishima, Nagomi Uchida, Hiroki Yoneda +2
The present study aims to reinforce the evidence for the ~9 s pulsation in the gamma-ray binary LS 5039, derived with a Suzaku observation in 2007 and that with NuSTAR in 2016 (Yon…
