Center-to-limb variation of quiet Sun (Allende+, 2004)
Solar observations of the center-to-limb variation of several spectral lines were carried out in October 22-23, 1997, with the Gregory Coude Telescope (GCT) and...
Center-to-Limb Variation of the Magnetic Field Vector Distribution in the Internetwork
I present a comparison between the Probability Density Functions of the magnetic field strength, inclination, azimuth, and filling factor determined at four...
Central star formation and chemical enrichment in CALIFA interacting galaxies
One of the main mechanisms to increase star formation activity is through galaxy interactions. Tidal induced inflows of metal-poor material are responsible of...
In this brief invited review, I will attempt to summarise some of the key areas of interest in the study of central stars of planetary nebulae which (probably)...
Central stellar mass deficits of early-type galaxies
The centers of giant galaxies display stellar mass deficits (Mdef) which are thought to be a signature left by inspiraling supermassive black holes (SMBHs) from...
Centre to Limb Variation of the Internetwork Magnetism
We analyse 1.5 μm spectropolarimetric observations of quiet regions at different positions on the solar surface. Neither the circular and linear polarization...
