The orbital parameters of the binary BLAP HD133729 : advantages of the frequency modulation method
Hiromoto Shibahashi, Donald W. Kurtz, Simon J. Murphy
We derive all the orbital parameters of the blue large-amplitude pulsator (BLAP) in the binary system HD133729 by exploiting the frequency modulation (FM) method, which is based on…
