Two rings but no fellowship: LoTr 1 and its relation to planetary nebulae possessing barium central stars. (2014). Revista Mexicana De Astrofísica Y Astronomía Serie De Conferencias, 44, 60-60. https://astronomia.unam.mx/journals/rmxac/article/view/2014rmxac..44...60t
Abstract
LoTr 1 is a planetary nebula thought to contain an intermediate-period binary central star system (orbital period, P ∼ 100-1500 days). The system shows the signature of a K-type, rapidly rotating giant, and most likely constitutes an accretion-induced post-mass transfer system similar to other PNe such as LoTr 5, WeBo 1 and A70.
