PublicationApplicability of Milne-Eddington inversions to high spatial resolution observations of the quiet Sun
Context. The physical conditions of the solar photosphere change on very small spatial scales both horizontally and vertically. Such a complexity may pose a...

PublicationAre Electric Currents Heating the Magnetic Chromosphere?
This Letter presents an analysis of three-dimensional vector currents and temperatures observed in a sunspot from the photosphere to the chromosphere, spanning...

TalkAre magnetic fields shaping PNe?
This question is important because a large fraction of planetary nebulae (about 80%) are bipolar or elliptical rather than spherically symmetric. Modern...

PublicationAre solar acoustic modes correlated?
We have studied the statistical properties of the energy of individual acoustic modes, extracted from 310 days of GOLF data near the solar minimum. The...

PublicationAre Tornado-like Magnetic Structures Able to Support Solar Prominence Plasma?
Recent high-resolution and high-cadence observations have surprisingly suggested that prominence barbs exhibit apparent rotating motions suggestive of a tornado...

PublicationAre young radio sources in equipartition?
Aims: The knowledge of physical conditions in young radio sources is important for defining the framework of models describing radio source evolution. We...
