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…
On the inversion of the scattering polarization and the Hanle effect signals in the hydrogen Lyman- line
R. Ishikawa, A. Asensio Ramos, L. Belluzzi +5
Magnetic field measurements in the upper chromosphere and above, where the gas-to-magnetic pressure ratio is lower than unity, are essential for understanding the thermal struc…
Time evolution of plasma parameters during the rise of a prominence instability
D. Orozco Suárez, J. A. Díaz, A. Asensio Ramos +1
We present high spatial resolution spectropolarimetric observations of a quiescent hedgerow prominence taken in the He I 1083.0 nm triplet. The observation consisted of a time seri…
Infrared extinction in the Inner Milky Way through the red clump giants
Carlos González-Fernández, Andrés Asensio Ramos, Francisco Garzón +2
While the shape of the extinction curve on the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be approximately constant, a r…
