Aceves Física, Astronomía y Matemáticas novae 58+184102 SDSSJ 122405 Binaries: general stars: individual We present observational evidence that helps classify the non-eclipsing binary system SDSSJ 122405.58+184102.7 as a new member of the SW Sextantis (SW Sex) class. First, from the analysis of the optical light curve, we identify the presence of two periodic signals that develop on different time scales. The first one is the orbital period of 0.167811(1) days (= 4.027464 (3) h) and the second one is the white dwarf spin period of 28.6 minutes. This second period is probably the first evidence for the presence of a magnetic white dwarf in the system. The second evidence is the presence of the HeII λ4886 emission line in its optical spectrum. In this work we interpret the detected periodicities within the context of a magnetic accretion model for SW Sex stars. 2020 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171642003 https://www.redalyc.org/journal/571/57171642003/ https://www.redalyc.org/journal/571/57171642003/html/ https://www.redalyc.org/journal/571/57171642003/57171642003.epub https://www.redalyc.org/journal/571/57171642003/movil 10.22201/ia.01851101p.2020.56.01.03 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.56 |
