Star-disk interaction in classical T Tauri stars revealed using wavelet analysis
J. Lopez-Santiago, I. Crespo-Chacon, E. Flaccomio +3
The extension of the corona of classical T Tauri stars (CTTS) is under discussion. The standard model of magnetic configuration of CTTS predicts that coronal magnetic flux tubes co…
Thermal structure of hot non-flaring corona from Hinode/EIS
A. Petralia, F. Reale, P. Testa +1
In previous studies a very hot plasma component has been diagnosed in solar active regions through the images in three different narrow-band channels of SDO/AIA. This diagnostic fr…
X-ray flares on the UV Ceti-type star CC Eridani: a "peculiar" time-evolution of spectral parameters
I. Crespo-Chacón, G. Micela, F. Reale +3
Context: Weak flares are supposed to be an important heating agent of the outer layers of stellar atmospheres. However, due to instrumental limitations, only large X-ray flares hav…
X-ray emission from dense plasma in CTTSs: Hydrodynamic modeling of the accretion shock
G. G. Sacco, C. Argiroffi, S. Orlando +3
High spectral resolution X-ray observations of CTTSs demonstrate the presence of plasma at T~2-3X10^6 K and n_e~10^11-10^13 cm^-3, unobserved in non-accreting stars. Stationary mod…
X-ray flares of the young planet host DS Tuc A
I. Pillitteri, C. Argiroffi, A. Maggio +5
Abridged. We observed the 40 Myr old star DS Tuc A with XMM-Newton and recorded two X-ray bright flares, with the second event occurring about 12 ks after the first one. Their dura…
Spin-Orbit Interaction Induced in Graphene by Transition-Metal Dichalcogenides
T. Wakamura, F. Reale, P. Palczynski +6
We report a systematic study on strong enhancement of spin-orbit interaction (SOI) in graphene driven by transition-metal dichalcogenides (TMDs). Low temperature magnetotoransport…
