The first observation shows a double-sided jet extending up to about 200 AU on both sides of a central source. The jet shows a bent S-shaped structure similar to the one displayed by the well-known precessing jet of SS 433 . The precession suggested in the first MERLIN image becomes evident in the second one, showing a one-sided bent jet significantly rotated with respect to the jet of the day before. We conclude that the derived precession of the relativistic (beta=0.6) jet explains puzzling previous VLBI results. Moreover, the fact that the precession is fast could be the explanation of the never understood short term (days) variability of the associated gamma-ray source 2CG 135+01 / 3EG J0241+6103" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "EDP Sciences" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1051/0004-6361:20031760" , "dc.relation.ispartof": "© Astronomy & Astrophysics, 2004, vol.414, núm.1, p.L1 - L4" , "dc.relation.ispartofseries": "Articles publicats (D-ATC)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Estels" , "dc.subject": "Estels binaris de raigs X" , "dc.subject": "Stars" , "dc.subject": "X-rays double stars" , "dc.title": "Hints for a fast precessing relativistic radio jet in LS I + 61° 303" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.identifier.doi": "http://dx.doi.org/10.1051/0004-6361:20031760" }
