Coronal energy release by MHD avalanches II. EUV line emission from a multi-threaded coronal loop
G. Cozzo, J. Reid, P. Pagano +13
MHD kink instability can trigger the fragmentation of a twisted magnetic flux tube into small-scale current sheets that dissipate as aperiodic impulsive heating events. This instab…
A reanalysis of the LHS 1140 b atmosphere observed with the Hubble Space Telescope
Alfredo Biagini, Gianluca Cracchiolo, Antonino Petralia +3
The super-Earth LHS 1140 b is an interesting target for atmospheric observations since it is close to the habitable zone of its star and falls in the gap of the radius distribution…
Signatures of X-ray dominated chemistry in the spectra of exoplanetary atmospheres
Daniele Locci, Giambattista Aresu, Antonino Petralia +3
High-energy radiation from stars impacts planetary atmospheres deeply affecting their chemistry, providing departures from chemical equilibrium. While the upper atmospheric layers…
The enigmatic dance of the HD 189733A system: Does the planet accrete onto the star?
Salvatore Colombo, Ignazio Pillitteri, Antonino Petralia +2
Several studies suggest that the emission properties of a star can be affected by its interaction with a nearby planet. However, the actual observability of these effects remains a…
Extreme ultraviolet and X-ray driven photochemistry of gaseous exoplanets
Daniele Locci, Antonino Petralia, Giuseppina Micela +3
The interaction of exoplanets with their host stars causes a vast diversity in bulk and atmospheric compositions, and physical and chemical conditions. Stellar radiation, especiall…
Magnetic shuffling of coronal downdrafts
A. Petralia, F. Reale, S. Orlando
Channelled fragmented downflows are ubiquitous in magnetized atmospheres, and have been recently addressed from an observation after a solar eruption. We study the possible back-ef…
