This subject is covered in
Travelling at the Speed of Thought: Einstein and the Quest for Gravitational Waves, Kennefick 2006, with reference to a 1909 paper by Einstein and Ritz. The illustrations are on pp 162, 163.
Last I checked, that link was a free PDF download of the 500-page book.
It looks to me like they are saying the spherical shells of light remain centered on the source in all inertial reference frames, even if the relative motion follows a straight line, rather an a circular orbit.
I am trying to relearn what little I used to know of Blender software. That's a bit like learning Italian so you can order pizza. I don't happen to have a pea shooter, so a stealth bomber will have to do.
I have drawn some circles to illustrate what would happen if you passed a pulsating star in a straight line at v =c/2. Now I have to relearn how to render the picture.
