The small-ELF project: toward an ultra-large coronagraphic optical receiver
The small ExoLife Finder (sELF) telescope is a 3.4m diameter fixed pupil tracking Fizeau interferometer. Its design relies on several new technologies the ELF...
The Solar Acoustic Spectrum as Seen by GOLF. I. The Difficult Case: Modes With n<10
Below 1.3 mHz the solar background level increases as well as the energy of the solar acoustic modes decreases. This situation yields the detection of low...
The Solar Acoustic Spectrum as Seen by GOLF. II. Noise Statistics Background and Methods of Analysis
Data acquired by GOLF experiment onboard SOHO during ~20 months has been analysed. GOLF is a disk-integrated sunlight experiment therefore biased to observe...
The Solar Acoustic Spectrum as Seen by GOLF. III. Asymmetries, Resonant Frequencies and Splittings
The definition of the model to fit to the observed spectra depends on the physics we are assuming is present in the phenomena we are observing. Here we present...
The Solar Acoustic Spectrum as Seen by GOLF. IV. Linewidth, Power and Energy of the Modes
The model fitted to the observed spectra also allows the measurement of the linewidth and power of each mode (see poster II). The linewidths are related to the...
One of the main drawbacks in the analysis of the dynamics of the solar core comes from the lack of consistent data sets that cover the low and intermediate...
The properties of solar photospheric inter-network fields are studied using observations from the Advanced Stokes Polarimeter. By averaging over large areas of...
The Solar Orbiter Mission and its Polarimetric and Helioseismic Imager (SO/PHI)
We briefly outline the scientific and instrumental aspects of ESA's Solar Orbiter mission. Special emphasis is given to the Polarimetric and Helioseismic Imager...
