Effects of the convective field on weakly outgassing comets
Galand, M.; Beth, A.
By applying a kinetic approach, we have developed two models in order to assess the influence of one main driver of plasma acceleration, the convective electric field, on the cometary ion distribution at 67P/Churyumov-Gerasimenko (67P/C-G). This electric field is carried by the solar wind and corresponds to the acceleration undergone by cometary i…
La poussiere cosmique
Rotundi, Alessandra
Since the 1970s, dust has been collected in the terrestrial environment in the hope of studying dust particles witnessing the primordial protoplanetary nebula materials. In the 21th century, cometary dust was collected by the Stardust/NASA probe in the coma of comet 81P/Wild-2 and returned to Earth. Cometary dust was also analyzed in situ by Roset…
News on the X-ray emission from hot subdwarf stars
Mereghetti, Sandro; Palombara, Nicola La
In latest years, the high sensitivity of the instruments on-board the XMM-Newton and Chandra satellites allowed us to explore the properties of the X-ray emission from hot subdwarf stars. The small but growing sample of X-ray detected hot subdwarfs includes binary systems, in which the X-ray emission is due to wind accretion onto a compact compani…
The evolution of geomagnetotail magnetic flux in isolated substorms
Dunlop, M.; Rong, Z. J.; Shen, C. +4 more
The magnetic field energy stored in geomagnetotail released during a substorm period, cause significant magnetic disturbance of the space environment. The quantitative relationship between the magnetic field energy and the level of substorm activity, however, is still unclear, although many studies have qualitatively revealed the correlation betwe…
Observational constraints on inflation with the nonlinear sigma-fields in light of Planck 2015
Koh, Seoktae; Lee, Bum-Hoon; Tumurtushaa, Gansukh
We study an inflation model with a nonlinear sigma field which has SO(3) symmetry. The background solution of the nonlinear sigma field is linearly proportional to the space coordinates while keeping the homogeneous and isotropic background spacetime. We calculate the observable quantities, including the power spectra of the scalar and tensor mode…
