Sub-terahertz, microwaves and high energy emissions during the December 6, 2006 flare, at 18:40 UT
Pierre Kaufmann, Gerard Trottet, C. Guillermo Gimenez de Castro +4
The presence of a solar burst spectral component with flux density increasing with frequency in the sub-terahertz range, spectrally separated from the well-known microwave spectral…
Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star
A. F. Lanza, I. Pagano, G. Leto +18
The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered as a good proxy for the Sun a…
Estimating stellar rotation from starspot detection during planetary transits
Adriana Silva-Valio
A new method for determining the stellar rotation period is proposed here, based on the detection of starspots during transits of an extra-solar planet orbiting its host star. As t…
Association of mid-infrared solar plages with Calcium K line emissions and magnetic structures
R. Marcon, P. Kaufmann, A. M. Melo +2
Solar mid-IR observations in the 8-15 micrometer band continuum with moderate angular resolution (18 arcseconds) reveal the presence of bright structures surrounding sunspots. Thes…
Observed flux density enhancement at submillimeter wavelengths during an X-class flare
G. Cristiani, C. G. Giménez de Castro, M. L. Luoni +3
We analyse the 30 October, 2004, X1.2/SF solar event that occurred in AR 10691 (N13 W18) at around 11:44 UT. Observations at 212 and 405 GHz of the Solar Submillimeter Telescope (S…
