Constraining the shaping mechanism of the Red Rectangle through spectro-polarimetry of its central star
M. J. Martinez Gonzalez, A. Asensio Ramos, R. Manso Sainz +2
We carried out high-sensitivity spectropolarimetric observations of the central star of the Red Rectangle proto-planetary nebula with the aim of constraining the mechanism that giv…
Hierarchical analysis of the quiet Sun magnetism
A. Asensio Ramos, M. J. Martínez González
Standard statistical analysis of the magnetic properties of the quiet Sun rely on simple histograms of quantities inferred from maximum-likelihood estimations. Because of the inher…
Upper limits to the magnetic field in central stars of planetary nebulae
A. Asensio Ramos, M. J. Martinez Gonzalez, R. Manso Sainz +2
More than about twenty central stars of planetary nebulae (CSPN) have been observed spectropolarimetrically, yet no clear, unambiguous signal of the presence of a magnetic field in…
A search for magnetic fields on central stars in planetary nebulae
F. Leone, R. L. M. Corradi, M. J. Martínez González +2
One of the possible mechanisms responsible for the panoply of shapes in planetary nebulae is the presence of magnetic fields that drive the ejection of ionized material during the…
